Congratulation! Do you win yesterday on the Ebay the machnines without accessories?
30 years ago where you see the Enterprise? For example PCW show or magazines?
Didnt come woth power supply whatbare the specs /what do i need?
Photos of original Enterprise PSUs. (http://ep.homeserver.hu/Galery/Alapgep/Picture/IM000729.jpg)
The most important thing: the outer pole are the positive!
The ZX Spectrum (16/48/+/128/+2) PSUs are compatible but the +2A/+2B/+3 no!
128 or +2 type recommended because higher capacity.
Whats next, i need to find some software etc to test /use, iss their a wiki/ starting point?
The best starting point this forum! :-) If you have any questions just ask it!
On my page (http://enterprise.iko.hu/) you can download scanned English manuals.
From the ep128.hu (http://www.ep128.hu/) you can download all Enterprise softwares.
You can send programs with audio cable from your PC to Enterprise.
With MrPrise TAPir program (http://enterpriseforever.com/emulatorok/tapir/?action=dlattach;attach=7584) you can convert programs to WAV, and possible burn these to CD and use diskman as "tape player". Or convert WAVs to MP3 (using very high bitrate!) and MP3 Player also can be used, someone used mobile phone MP3 Player software.
What do you recommend i buy next?
For the first step after the PSU I recommend a SCART cable for the best picture quality.
Sometimes will be on the Ebay, but if you have some electronics experience the easy to build your own.

Like Zozo says a good Speccy PSU will do the trick.
128K+ is 9v 1.85A or a Speccy+2 is 9v 2.1A.

cheers
yes won both the 64 & 128 yesterday on ebay!
I have spectrum psus so that's all good.
from what I can gather rgb wise I need a 2.54mm pitch edge connector cut to size? (14 pin)
-
I first saw it previewd in magazines in 82/83 as samurai etc,
then I saw it in flesh at "Scottish Computer Show" in Edinburgh in 83? I think, it was badged elan at the time,
and was blown away, started saving my pocket money.
By the time I saw one in real life after release 85?(once in a John Menzies computer dept), never seen or touched since...

Great start! The machines have a Basic cartridge? (On the photos I not see them).
If no then you need it. But you can run machnie code programs without cartridge!

Yes, you can found on Ebay (http://www.ebay.co.uk/itm/2-54mm-0-1-DOUBLE-SIDED-EDGE-CONNECTOR-GOLD-PLATED-PHOSPHOR-BRONZE-CONTACTS-/190633135705?pt=UK_Sound_Vision_Other&hash=item2c629ece59) the remains will be good for other cables (joystick, printer).

Because the long delay you bought another computer before the Enterprise really launched?

You will not be disappointed! Fantastic machine :smt023

I asked the seller: serial number of 128K machine is 00630, it is a very early machine!
The EP64 is 032285.
Zozo what is the relevance if low serial etc?
Are these two good machines i have bought? Do you think?
Do you need me to open and check mboards etc for you?
-
Assuming they dont. Whats the bestnplace to find one? Ebay?
Yes, but the Basic is very rare :-( But I can sell one :-) not just Basic, for the remaining space can be placed other programs.
-

On the photos looking good, and important: both have the joystick cap for the internal joystick! This little piace are the first missing part of many machine, near to impossible find spare. (My hope the 3D printing will be common then possible produce spare parts).
Do you need me to open and check mboards etc for you?
Not needed especially if the Serial/Warranty label still intact. I wrote instructions (http://enterpriseforever.com/hardware/your-enterprise-configuration/msg28168/#msg28168) how can detect motherboard version on unopened machine.
Please make photos of serial labels and send to me for the inventory (http://enterprise.iko.hu/inventory.htm), with details. (Machine with intact label more evidence because can be sure the motherboard not changed.)
I looking for special questions for example exist a EP64 with ISSUE6 board or EP128 with ISSUE5?
From the current data I think the EP128 started with ISSUE6 but some bad ISSUE4 remainded from the early EP64 production, these after repaired put back to the production.
The interesting on the ISSUE4 boards the company name FLAN instead the Enterprise! One name earlyer, and this name only valid for about 1 month (1984 February-March).

Sounds good, I willtake you up on that offer, I will wait to see what arrives with these enterprises first?

Ok, firstly see what you get.

Hi Zozo
I have the machines in hand now.
to me both look Issue 4, will confirm 100% by opening up, the 128 has a lot of grime & dirt around keyboard so will need cleaned properly etc.
Unfortunately as expected did not come with anything extra so Ill need to get a basic cartridge, does the same carrt work on both machines? I seem to remember reading the 64 and 128 had different revisions?
-
which email do I send pics of labels etc to?
is there a disassembly guide or is it straightforward enough?
where would the warranty label be (when you ask label intact?, is there a screw under the serial number etc)
-

At this topic we talked about the keyboard cleaning. (http://enterpriseforever.com/hardware/how-to-clean-the-enterprise/)

Yes the EP64 come with version 2.0 and EP128 with 2.1. But the 2.1 also work with EP64.
-
thanks zoz as above what email do I send pics of labels t for the registry etc?
and is there a disassembly guide for whole machine?
-

I sent PM to you.
is there a disassembly guide or is it straightforward enough?
It is very simple. In previous post I linked how to disassemble the keyboard.
On this photo (http://enterpriseforever.com/other-topics/how-to-clean-the-enterprise/?action=dlattach;attach=1014;image) are red marked the screws for the keyboard. You can see another 5 screws these needed to removed if you want completly disassemble the machine.
One at the corner of the Serial/Warranty label. I think voiding the warranty don't a big problem after 30 years :-) but the intact label are very rare todays. If your label intact then very carefully can blend up the corner of label for accessing the screw.
where would the warranty label be (when you ask label intact?, is there a screw under the serial number etc)
At the bottom of machine you see on the photo.
If all screws removed then can lift up the top part of case. Do it very carefully because the keyboard membrane connected to the motherboard! Can broke the connection trails! Firstly lift up the front (keyboard) part of the top, until you can access the membrane connection, then pull out from the motherboard connectors, then can fully remove the top part of case.
Do you tested the machines, keyboard fully working? Very common problem with the 30 years old membranes: it is start broke at the connection, then rows or columns of keys are dead. At this situation can be repaired by cutting broken few milimeters from the connection trails at the end.

lol! ty
haven't powered them up yet to check functionality, will try tionight maybe when I get home, will probably have to make rgb cable first though as not too hopeful of getting picture from rf on my lcd tv
can you sell me a basic cartridge as discussed?
how about tape leads? what are the specs?
-

The EP have a internal speaker, you can hear keyboard Click sound when pressing keys. (After the powerup wait few second to memory testing, more on 128K machine)
Then without display you can test the computer started, and most of keys working (not all generate sound).
can you sell me a basic cartridge as discussed?
Yes and also possible put other programs beside Basic for fill whole 64K.
how about tape leads? what are the specs?
Are totally common 3.5 jack audio cables. Any standard casette recorder can be used.
Remote controlling are optionaly for this needed a 2.5 jack cable. The original cable have one wire with 3.5 jacks and one with 2.5 jacks.
If you need I can send original cable.
-
brilliant I would love a proper cassette cable.
what other stuff is recommended to fill the 64k basic cart?
email me some paypal details and I will sort you out money and my address for the cart/lead
-
Ok tested the 64 last night, appears to be fully functional boots into the word processor, and all keys work!

Great news!

what other stuff is recommended to fill the 64k basic cart?
I highly recommend my Quick RAM test, it is also include the WP 2.6
It is 16K, BASIC also 16K, then 32K remaining.
With my RAM test can put 32K SRAM chip to cartridge, then you got 32K memory expansion.
Other choice put another programs to this 32K, there is some for selection:
Other programing languages:
IS-FORTH 16K
IS-LISP 16K
HiSoft Pascal 32K
Assembler/Monitor/Disassembler: ASMON 32K
Cyruss Chess II 16K
(PS: I got the photos, thanks!)
-
basic + RAM test is good
other 32k
I assume I could load any of these via tape/disk also if required?
IS-forth & is-lisp would be my choice
I have just received the bits to build rgb cable so will do at the weekend as rf picture was very poor on my tv (but good enough to check functionality)
128 has a coup[le of keys stuck so disassembled keboard and cleaned it up(rubber membreane and general crap between keys)
keys are no loger stuck so hopeful that when I fire it up tonight it will be ok maybe...
-

Yes, all have loadable version.
IS-forth & is-lisp would be my choice
Ok, I will make it in the weekend.

I used to program forth many years ago using Jupiter ace computer in mid 80s! haven't looked at it for about 30 years!!!!!
will be interesting Lisp experience about 1983 on BBC Micro!

Wow!
Scanned manuals for the Enterprise versions:
IS-FORTH (http://enterprise.iko.hu/books/IS-FORTH.pdf)
IS-LISP (http://enterprise.iko.hu/books/IS-LISP_English.pdf)
And few weeks ago started a FORTH topic. (http://enterpriseforever.com/programming/forth/)

I have now tested the EP128 after the semi cleanup, powers up ok and keyboard all working!!! :lol:

absolutely delighted just finished cleaning both up(both quite bad but 128 was covered in "brown" stuff sticky almost)
both now look almost factory new, and both 100% working (as far as i can test)
:lol::ds_icon_cheesygrin:
might post a few pics later because they both look beautiful just how i remember seeing them in magazines and
at computer show 30 years ago!!!

whoop!
Received the following in the mail today from the ebay seller (they found some bits to go with the machines)
Any idea if that is 2x basic carts? Why does one have no label? Is it a dev/early cart?
And importantly 1x copy of wizards lair which was written on these very 2 machines i now own!
I also bought from seller 1 of the development Tatung Einstein machines which they used to code games with. im hoping to find some source code on the disks for maybe wizards lair but also starquake!!!
-
Wow! It is near all missing accessories of your machines! (PSUs, cables still wanted)
The labeled cartridge is for EP64, other for EP128. Probably no label because cost reduction?
-
i am very happy.
