Hello everyone,
my name is Thomas and, as the subject says ;), i'm from Germany. I'm a collector of game consoles and home computers.
Well, my personal Enterprise-story begins in the 80s. I was a happy Atari 800XL-user, had friends with Commodores and Schneider CPC (the german versions of Amstrad CPC). At this time i read many magazines like the german Happy Computer, Computer Kontakt and HC-Mein Homecomputer. In one of this magazines i saw an article about a brand new computer that would be released later in the year: The Enterprise. I actually don't remember if thr name of the computer was still Elan Enterprise or only Enterprise. But i was fascinated. So much colors, up to 4MB RAM, an integrated joystick and a really cool design. From this moment on in wanted such a computer. But as time went on i didn't heard more about this computer for a long time. But sometimes a thought "Hmm, i'm curious what happened to this computer ... was it ever released ?"
Then the internet came and so the chances to research for all the interesting things ... like the Enterprise-Computer. And so i found some websites, photos and much other things. And again i thought "It would be great to own such a cool Computer".
About one year ago i searched eBay for classic computers. And what did i found ? An Enterprise 128-computer ! Boxed, in great condition, from Hungary. Well, after 1 minute of thinking i hit the "Buy it now"-button. And so it happened, i got my first Enterprise-Computer ! I was so excited ! As one of my hobbies i write for a german retro magazine. So after receiving the Enterprise i decided to write an article about the Enterprise. It was planned with 4 pages, but i found so much things about the Enterprise, the fascinating story, so now the article has 7 pages ;)
And in december 2012 i got my "personal christmas present to myself": When i searched eBay i found an Enterprise-system, shipped from Germany ... with EXDOS, all manuals, "Chip-Sonderheft", a german special issue of the Chip magazine about the Enterprise and tons of other really interesting things like original price lists, a software Spectrum-emulator with manual. I bid, crossed my fingers ... and won the auction :)
So now i have 2 Enterprises, EXDOS, and as a floppy replacement i actually use a HxC floppy emulator with SD-Card.
At home i'll check the serial numbers of my components so you can use them in your database. This weekend we have a retro computer meeting with much C64s ... and i'll bring my Enterprise ^^
OK, that's my first post ... but definitely not my last post ;)
I'm happy to be here and to meet more Enterprise-enthusiasts :)
Greetings from Germany
Thomas

Thomas! Welcome here!
It is very interesting your story, because the second Enterprise headquarter is in the Germany! Enterprise Computers Gmbh, started at 1985 Aug. 13. and it is still working in the early 90s!
Probably not made too good marketing works, if you not hear anything about the Enterprise in these years :(
-
Welcome Thomas,
It is always a pleasure to welcome new members on our forum!
It seems you felt in love with this little machine at first sight, just like most of us here ;-)
I still rememember how much I liked her colored buttons, her shape, even her red reset button! It was so cooll. Then it became even better after our friend turned it on. The mesmeric TESTING at the top followed by the big, colorful and blinking ENTERPRISE text. Then came the classic games like Batman, Sorcery, Wriggler and they burned into my brain forever. I did not know much about the machine first, I just knew whoaa. I was a kid, but the first experience was more than enough to want to learn more about computers and especially about the Enterprise. The truth is the more you learn about it, the better you will love it.
Could you post your article here on our forum? We now have a dedicated German section.
-
@Zozo:
Yepp, the article in this magazine was the only time i've seen the Enterprise. At this time i've never seen an Enterprise in the shops or malls. The marketing was awful, from what i heard the computer was sold in some stores where you never expect to see home computers.
But they were active in selling hard- and software by mails. I have some official price lists, also some official letters to the previous owner of my second Enterprise with the official Enterprise-logo- I can scan them if you are interested :)
@MrPrice:
Yepp, it was love at the first side. The sad story was that we never met for years ... but after the years when we finally met the computer was as beautiful as before and also the love was the same :)
Jepp, i posted the story also in the german section as a reply. I hope that more german Enterprise-fans will find this forums so the section will grow more and more :)

Here are my 2 beauties:
The CGI-model is a 3D-model of my first Enterprise. It was modeled by a friend and used in the RETURN-magazine.
The photo shows my second Enterprise with EXDOS and the manuals, magazines etc.

Nice pictures :) The 3D model one looks like a real machine which just came out from the factory :)

This weekend we have a retro computer meeting with much C64s ... and i'll bring my Enterprise ^^
Also bring some nice demos! (http://ep128.hu/Ep_Demo/Demo_eng.htm) The Interlace demo 2&3 highly recommended if you want to demonstrate full power of the Nick chip.

If you plan to bring some interlace demos also then please check the pictures both on your computers, hopefully one of them has a bugless NICK.
-
Yeah, i just downloaded all demos from the website and tried the Interlace demo 2 on an emulator. It looks awesome !
Oh, some of the Nick chips have bugs ? Especially with the use of the Interlace modes ?

Mainly with interlace, it has problems if I remember well when the chip usage is high, then more or less pixel get strange colors on the screen. Zozo can explain it in more detail.

Ah, ok, so i think i should bring both of my Enterprises to the meeting (it's already packed). Only to get sure ;)
-
Mainly with interlace
Mainly with attribute graphics. The older Nick have 08-04 part number, the fixed version is 08-47.
For example see the eszakif (northern lights) picture from the interlace pack. There is as separate executable file (http://enterpriseforever.com/hardver/pixelhibas-alaplapok/?action=dlattach;attach=2944) for quick testing.
This is the right picture. (http://enterpriseforever.com/hardver/pixelhibas-alaplapok/?action=dlattach;attach=2927;image)
And picture with errors... (http://enterpriseforever.com/hardver/pixelhibas-alaplapok/?action=dlattach;attach=2915;image) note this is a worst case photo! The error rate depends from the Nick temperature (if the glue aged and the heatsink dropped then worse), and also from Nick is from better or worse series.
The 08-47 works without error also when no heatsink.
If your motherboard have a bright green PCB then probably you have 08-47 Nick.
The dark green boards have mixed Nicks.

Ah ok, Thanks for the explanation :)
Well, the Enterprise that i want to show at the meeting is already well packed in a box. But i will also take my other Enterprise to the meeting, it's a good test which Nick is ok :)
I'll also check the motherboards then. Are the 08-47 Nicks used from a serial number or are they completely mixed ?
-
I'll also check the motherboards then.
I wrote there (http://enterpriseforever.com/hardware/your-enterprise-configuration/msg28168/#msg28168) how you can identify motherboard version. You also see the color difference of PCBs.
Are the 08-47 Nicks used from a serial number or are they completely mixed ?
Good question! For the answer needed feedback from lot of users :oops: I think the first x thousands are mixed and later series are only 08-47.
But the later motherboard changes can mess up the statistics :evil: especially with the Ebay machines, if the seller have a "good looking but not working" and "working but not good looking" machines then will made one "good looking and working" and one "only for spares" machines with motherboard replace.
-
OK, i checked it out, it seems that at least one of my Enterprises has this buggy Nick. I only took one of the Enterprises to the retro computer meeting, the one with the low serial number (12xxx). On monday, when i'm back home, i'll test the other Enterprise (afaik with s/n 22xxx)
-

Bad news :(
But you found another demos what can impress C64 boys?
-
Bad news :(

Well, i found some demos, but in my opinion the most impressive demos are the interlace-demos ;) I used the Bigdemo, Visions, 3D, Megademo and some others, also some games like Cauldron and Sorcery. For the next meeting i'll check imy other Enterprise has a non-buggy Nick, so i'll take this one to the meeting :)
-
Also try it: Small Demo, Scroll demo, Show of Magic Balls, Ork Megademo
-
The photo shows my second Enterprise with EXDOS and the manuals, magazines etc.
Can you write list which manuals, magazines, other papers you have?
And the lot of disks and some tapes are also interesting! :oops:
Probably you have something what we never see!

Sure, no problem :) I'll be back at home tomorrow, so i'll send you the list tomorrow evening.
One of the magazines is this here:

also the German User Manual :oops:
Nobody in the forum has the German User Manual? It's surprising...
I didn't understand why I couldn't find it on the net.
People who have German machines: do they not have the manual? How can it be?

Part 1: The manuals and software that i have here at work. The other ones are at home ;)
There are also some 5,25"-disks that are unlabeled. So i have no idea if they are empty or filled with some great programs.
-
From the disks can you create disk images?
-
I have the German EXDOS book (http://enterprise.iko.hu/books.htm), but only as copy. Can you scan the colored cover in same resolution?
In the EXOS Technical Manual all parts numbered, can you compare the versions with these? (http://enterprise.iko.hu/technical.htm)
-
THe technical manual is EXOS 2.0, November 1984, ET20
OK, i'll scan the cover and create images from the disks. The 5,25"-disks are also standard-FAT-disks, so i can read them with a standard-PC-drive, right ?
I''ll make a list of the other manuals and papers that tonight when i'm back at home.
-

Are the chapter numbers also the same?
The 5,25"-disks are also standard-FAT-disks, so i can read them with a standard-PC-drive, right ?
Yes, but the stupid Microsoft systems can't read all standard disks :evil:
The NT family only read DD disks: 80 tracks 3.5" and 40 tracks 5.25".
If you have a problem, I wrote a little program (http://enterpriseforever.com/egyeb-temak/pc-s-programok-enterprise-hoz/msg24355/#msg24355) for MS-DOS, create or write back disk images. Needed boot to real DOS for using it.
-
Are the chapter numbers also the same?
yes, the chapter numbers are the same (2.0), only the Keyboard driver has the date 26-Nov-84 instead of 29-Nov-84, but has the same chapter number (ET13/5)

ah, ok, i'll check it out. Maybe the floppy emulator software can read this images (it has an option "Floppy disk dump"), maybe Omniflop (http://www.shlock.co.uk/Utils/OmniFlop/OmniFlop.htm (http://www.shlock.co.uk/Utils/OmniFlop/OmniFlop.htm)).
-
Thanks! We are very interested! (You can send to my email, and I will put to my page. (http://enterprise.iko.hu/) )
OK, you also asked for my tapes. Here's a list:
- Demonstrationskassette (shipped with the computer)
- Beach-Head
- King of the Castle
- Airwolf
- Race Ace
- Orient Express
- The Abyss
==> These tapes are with the original black inlay and english manuals
- Dot-Breaker
==> with an orange inlay, looks like handdrawn, but it seems that it's original (see the attached photos)
- BASIC converter Sinclair -> Enterprise ( i also have the manuals, separate in A4)
- Paintbox
OK, i also attached some photos of the manuals, schematics and price lists. What scan resolution do you prefer :)
I will scan them in the next 2 weeks and send them to you by mail.
-
Thanks! Lot of interesting item!
I like least 600 DPI :-)
-
The English EXDOS manual and the EUG Lorch Info is on my page.
For the schematics look at there (http://enterprise.iko.hu/schematics.htm) and what you not found (for example the cable connection pages) needed to be scanned.
And also if you found your version more readable or different version than the existing then also please scan it.
And I think the folder with the pricelist is full with treasures!
We have a different release from Dot Breaker:
Cover (http://ep128.hu/Album/Ep_Kazetta/DotBreaker-DotCollector_HIGH.jpg) Tape (http://ep128.hu/Album/Ep_Kazetta/Kazetta/DOT-Breaker.jpg)
Can you scan your version?
-
I added a lot of German price lists here. (http://enterprise.iko.hu/historical.htm) And brochure of the Enterprise Disk Drive (http://ep128.hu/Album/Pic/FDD35_2.jpg) at there. (http://enterprise.iko.hu/brochures.htm)
Thanks Thomas!
-
No problem :) I'll scan the rest of the price lists, letters, schematics and the other stuff in the next days.
Because of Dot Breaker: I have this version. It's an older scan, i'll rescan the cover together with the other stuff, also the tape (it's also different from your version).
Edit: Oops, i've just noticed that i posted a photo of the tape before ;)
-
No problem :) I'll scan the rest of the price lists, letters, schematics and the other stuff in the next days.
Is any news? :oops:

Tom!
Can you help translate the EXOS 2.4 keys help texts to German?
[attach=1]
-
Is any news? :oops:
Sorry, i had much work and strange weeks :oops: From 29.04. 'til 01.05. i have some free days, i'll scan the rest of the documents in this days.

Tom!
Can you help translate the EXOS 2.4 keys help texts to German?
(Attachment)
Sure :)
From the beginning of the screen:
"TESTED" = "GETESTET"
"QUICKTEST" = "SCHNELLTEST"
"WRITTEN BY" = "ENTWICKELT VON"
"HOLD = pause testing" = "HOLD = Tests anhalten"
"(C)old reset" = "(C) Kaltstart"
"(E)XOS reset" => no translation necessary
"(A)dvanced Test" = "(A) Erweiterter Test"
"(N)ormal test" = "(N)ormaler Test"
"(T)est-rom enable" = "(T)est-rom aktivieren"
"(R)amdisk delete" => If this means to delete the Ramdisk, then the translation is "(R)amdisk löschen" (or "(R)amdisk loeschen" if yo don't have the german special letters like ö, ä, ü and ß). If it means to disable the Ramdisk, then the translation is "(R)amdisk deaktivieren"
"F1: test only to F8" = "F1: Tests nur bis F8"
"5, 6, 7, 8: test to 5, 6, 7, 8" = "5, 6, 7, 8: Test bis 5, 6, 7, 8"
"F2: ... " = "F2: Originaler EXOS Rom Test"
"F3: ..." = "F3: Überspringe ROM Gleichheits-Check" => not sure, if this is the really correct translation
"F4: ..." = "Lösche ROM Simulationen" => The same as the Ramdisk: If it means to disable it, then the correct translation is "Deaktiviere ROM Simulationen"
"F5: ..." = "Lösche EDCW-Erweiterungen" => same here as F4, delete or disable ?
"STOP: ..." = "Halte an, wenn fehlerhafte Segmente gefunden wurden"
"ESC: ..." = "Springe zum Startbildschirm"
The problem is that many of the german words are longer than their english counterparts, so usually the screens doesn't have enough space for it. Then you can use shortcuts, like "STOP: Halt, wenn fehlerh. Segmente gef. wurden".
But i think most of the german Enterprise-users would prefer the english translations ;)
-
Thanks!
But i think most of the german Enterprise-users would prefer the english translations ;)
It is very interesting! Also prefer English Enterprises instead the German version?
-
Thanks!It is very interesting! Also prefer English Enterprises instead the German version?
Well, i think for word processors and business use an Enterprise with a german keyboard is better. For programming it doesn't matter if you use a german or an english enterprise. But a BASIC with german messages was a really novum, i think it helped people who doesn't speak english to understand what the computer want ;) Otherwise english messages also helps to learn the english language ;)
In my case i like the german Enterprises because it wasn't really common in these days to release a home computer with a german keyboard and german messages :)
Edit: The BASIC of the enterprise has good translations. But many translation in these days were really bad, so when you read it you didn't understand what the text means. So most users prefer the english text instead. Also there are some words that you can't really translate into german without destroying the meaning of the word ;)
-
Do you know anything about why German versions of Enterprise were made ?
I heard something: at that time there was a language law in Germany which order localized computers.
It is true?
In Hungary both English and German versions were sold. I started with German :-)
At that time I couldn't speak English or German either :oops:
Later the German extension ROM was modified to Hungarian version.
-
Hmm, i think that Enterprise Computers thought that it was an advantage in selling the computers when they have german keyboards. Also the german Enterprise division was big, so i think that's two of the reasons why there were 2 Enterprises, English and German.
I don't know about a law which order localized computers in Germany, but there was such a law in Spain. First all computers with 64kb RAM had to have localized spanish keyboards. That's the reason why there was an Amstrad CPC472 released in Spain. It has 8KM more, completely unused RAM, only because then the keyboard could be an english one. Later the law was extended to computers with more RAM, so the later Amstrad-computers had spanish keyboards. But as i know in Germany we didn't had such a law.

What do you think?
GETESTET instead of TESTED (in the first line)
Exos Reset (capital "R")
Lösche EDCW-Erweiterungen (missed "e")
Halt, wenn Fehler gefunden (capital "F")
Springe zum Startbildschirm (order of letters)
-
GETESTET instead of TESTED (in the first line)
The upper window are same in all versions.

Yes, that's correct, Thanks :)
Another correction:
"(T)est-Rom aktivieren" (capital letter)
Looks great :) I hope that "Gleichheits-Check" is the correct translation for that functtion ;)

Previously we know only 3.5" disk drive unit with built in EXDOS (http://ep128.hu/Album/Pic/FDD35_2.jpg), developed by the Enterprise Computers Gmbh.
The case (http://ep128.hu/Album/Pic/FDD35_3.jpg) looks enought big for 5.25" version. I thinked probably also exist 5.25" version.
In your pricelist (http://enterprise.iko.hu/historical/Preisliste_Hardware.jpg) talking about 5.25" version! Did you ever seen this type?
One of the latest documents what you sent yesterday talking about step rate speed problem. It is for this drive unit or for anyone who is use standalone slow drive?
-
Well, i don't know if an official 5,25"-drive existed here. The pricelist offers a complete drive with built-in power adapter, the invoice of the pre-owner of my system also shows that he bought such a kit. Unfortunally the drive wasn't included within my system, but a manual of the BASF 6106/6108 disk drive. I think that Enterprise sent him this drive together with the EXDOS-interface and maybe also a case. So the document about the steprate problem should be for the BASF 6106/6108 drive.
Edit: Ah, i see that the pricelist says "180kb". So the drive should be the single-sided BASF 6106
-
a manual of the BASF 6106/6108 disk drive.
This is? (http://ftp://ftp.cpcszene.de/pub/Computer/Allgemein/Floppys/BASF6106_6108.pdf)
-
Exactly, it's this drive, but i have another manual of it (the english technical manual)
Edit: Here are some english manuals:

-
Exactly, it's this drive, but i have another manual of it (the english technical manual)
If you have some time, can you scan it? :oops:
I will make page with floppy drive manuals.
For the BASF 6164 you see manual everywhere? This drive (http://ep128.hu/Album/Pic/FDD35_5.jpg) used in the official Enterprise disk unit.
I looked with google, but not found :-( But I searched in English :oops:

I'll also try to find some manuals for the 6164 :)

Added lot of new pricelists and some invoices from Germany. (http://enterprise.iko.hu/historical.htm)
(http://enterprise.iko.hu/historical.htm)
Thanks Tom!

Tom!
Can you translate which items on this list? (http://enterprise.iko.hu/historical/Pricelist_1988Jun.jpg)
I think the first is a upgrade EP64 to 128K, second is upgrade to 576K.
The third is ROM upgrade to 2.1 for EP64?
-
Jepp, that's right. The first is an upgrade for the Enterprise 64 to 128kb, the second one is an upgrade for the Enterprise 64 or 128 to 576kb. (I also have such an upgrade-board, i must check how to build it into the Enterprise 128 ;))
The third is that ROM upgrade to 2.1 for the EP64. For this you had to send in the computer and the BASIC-cart to the Enterprise service center where EXOS and BASIC were upgraded to 2.1.
Interesting is the fifth option. This is an upgrade of the BASIC-cart to a switchable cart where you can choose between a german and an english BASIC. I got such a cart together with my computer.
-
I also have such an upgrade-board, i must check how to build it into the Enterprise 128 ;))
I got such a cart together with my computer.
Can you make photos of these?
-
Can you make photos of these?
Sure :) Actually i'm not at home. I'm back on tuesday, so i'll make photos then.
-
OK, here are some photos of the RAM expansion and the switchable BASIC-cart.
For the expansion: Is it only necessary to replace the old 64kb-expansion of the EP128 with the 512kb cart ? And do i need the cable that goes from the original 64kb-cart to another ic ( i think, MMU, right ?)
-
Thanks for the photos! Can you take one more: inside of the cartridge?
I have a "Enterprise 576K"with same board, this was probably expanded at the Enterprise Gmbh:
[attach=1]
[attach=2]
[attach=3]
[attach=4]
[attach=5]
[attach=6]
[attach=7]
[attach=8]
And on another machine use same as additional extension (placed outside), this was expanded by myself :-) I did not use additional 7805.
[attach=9]
[attach=10]
-
And this is the prototype of this expansion board. I bought from the developer (Finn S. Nielsen) about one year ago.
[attach=1]
[attach=2]
[attach=3]
-
Wow, very nice :)
Well, it seems that the RAM-expansion is not only a cart replacement. There are also some cables and the 7805 (ok, which is not alwasy needed ;) ). Do you know if there is any manual available where to connect the cables ? So then i'll try to upgrade one of my Enterprises :)
For the BASIC-cart: I'll take a photo of the inside of the cart when i'm back home (so in the evening).
-
At this page (http://enterprise.iko.hu/pinouts.htm) you can find the pinout of the internal expansion connector.
On the small connector already the GND and +5V.
My 576K machine only uses 2x3 wires of this connector which are only the address lines. Then needed the additional GND and +5V wires.
Your board has a full 2x5 pin connector which are use the GND and +5V from the motherboard connector, as the original 64K board (and my "external" 512K).
You can see additonal wire (http://gafz.enterpriseforever.com/Galery/Alapgep/Picture/Enterprise_128_Mainboard_s2.jpg) at the end of 64K board, it connects the GND points of the board and the motherboard, for noise reduction.

Ah, this means that i only need to replace the cart, maybe solder the wires from the small connector (if there are no pins at the motherboard) and wire the GND from the cart to the MB ? That would be great :)
-
At default no pins at the motherboard. Remove the 64K board, clean the holes and put pin headers to both connectors.

Ah, great, then i'll try it out :)

Thanks for the photos! Can you take one more: inside of the cartridge?
OK, here's a photo from the inside of the cartridge :)

Thanks!
Same modifications (http://ep128.hu/Ep_Konyv/Pic/MikroM_2.gif) published in Hungarian Mikro Magazin. It is say the informations come from the Enterprise Computers Gmbh.
Anyway I developed some programs do this trick in software way.
With the RL command in the Zozotools can remove the German extension (or any other ROM) from the ROM list.
The DBASX can disable IS-BASIC extensions. If you use this then you can use the German keyboard handler and other functions of the German ROM (VLOAD,etc) just the German message handler not installed for the BASIC.
If this handler installed then some areas of the Basic moved to another location. Many Basic programs which are using direct POKEs (wrong idea on the EP!) then not running correctly on German machine. This is the main reason why needed to switch of the German extension. With the DBASX can easy disable the problematic part.

Ah nice :) I always wondered why there are these switchable languages on the cart, but with the incompatibility issues it makes sense :)
