Programming / Re: Sell ​​Exos 2.4?

Still thinking.... May be a proportional compensation to Zozo for his work would be to mention him in the Ebay announce. Also a link to this wonderful web could bring more Enterprise members.

I think that the distribution of the Rom is for free, it can be downloaded from this web even if not being a member.(And at the end it is based on the stock Enterprise Rom...)

Other thing is to benefit from others work, and I think that in this case Wolfgang is not profiting from the software, only from the installation of the software. The EP64 he sells is a complete product, I think it is correct that he announces those enhancements the computer has inside.

And if he doesn't sell for a fair price one of the three Enterprises he has then he can't buy one with the fixed nick....

He on the other hand, is a contributor to the EP scene, he has released completely free his Ram expansion design.

Hihetetlen! még másolatokat is készít magáról!

Kívánom, hogy legyen nagyon boldog.

Incredible! you even make copies of yourself!

I wish you to be very happy.

Úgy gondolom, hogy a RomBanks rendszere nem elég hasznos számunkra, mert nincs korlátozásunk a Romok számában, és a Romban csak néhány játék van.


I think that the system of RomBanks is not useful enought for us because we have not restrictions in the number of Roms, and there are only a few games in Rom.


Igen, a felhasználói azonosító és a jelszó feltöltése az INI fájlba nem kötelező, mert a programok mindig meg fogják kérni őket, ha nem találhatók meg.


Yes, putting the user ID and password on the INI file is optional, because the programs always will ask for them if not found.

Allf means that he needs some way to load files to the EP....

It is a pity we still don't have a SF3 driver. SD cartridges are out of stock, and TAPE: is possible, but slow.

Allf has a floppy controller but he has selected the wrong SF3 adapter or I have advised him badly....

I will think on a provisional solution. But first some tests.

Ah, yes... I have only repeated what you pointed some time ago.... but I didn't remember about executing TEXT blindly.

I don't only want to throw words as true: on the emulator or on the real machine, if you have a SD cartridge or a floppy controller you can try this:

-Write a one program line, for example 10 REM.
-Execute LIST to see you program list....
-Execute :EXDOS . This will open you an EXDOS screen where you can for example do a DIR.
-Press the ESC key. The EP will freeze, but if you press once the reset key you are again on Basic.
-Execute LIST.

You can also do the same with the included word processor:
-Execute :WP on the Basic editor. This will open the word processor.
-Write some random text
-Press F8 and execute EXDOS+Enter
-Again the EXDOS screen will open. Make a DIR.
-Press the ESC key. This time the EP has not freezed, and you have returned safely to the text edition.


Basic itself is multisession, you can edit several programs at the same time, even jump between them while on execution.

-Write this program:
20 CHAIN 1
-Execute this command: CHAIN 1
-Insert these lines:
10 print "HELLO"
20 CHAIN 0
-Execute this command: CHAIN 0

-You now see a flashing HELLO.

The CHAIN command not only swaps programs, also executes them.


Another proof that the EP is multisession: almost all programs and some games have a clean exit to EXOS:

-Basic has the ":"
-WP has the F8 key
-EXDOS has its prompt.
-Try to search the exit on other languages or utilities, like Hisoft-Pascal, Lisp, Forth, Epdos, EGI, PaintBox, IS-Chess, etc


The main tool to make this possible is an efficient management of memory. Every program will ask EXOS the necessary amount of memory, and at exit they have to free it, returning the memory to EXOS.

More advances, more stuff:

Wanted / Re: EP with working 08-47 Nick

Wolfgang knows what he says when he mentions the two Nicks.

The differences on the defective Nick are: strange pixel glows on multicolour screens, and bad external colour input. Also there are some EPs more affected than others. The cooper heat-sink over Nick seems to slightly attenuate the issue.

None of the two errors happen on a normal use. Nick Toop, the creator, said it was a production defect, his high end design was too much advanced for the manufacturing techniques on these days.

It would be very cool to see an Enterprise with the full 4Mb.  I still need to get my Enterprise motherboard working and wired up with a keyboard, maybe a project for after that...

It can be done, I have filled every single segment with Ram/Rom with the aid of the SymbiFace3 board. Amazingly, the system behaves the same as on a 128KB model, total stability.

.....But, there's no Enterprise-specific (i.e. EXOS) software that needs more than 512KB, is there?

Any there many (or any) EXOS programs that need more than 128KB?

On classic times coders took the 128KB Enterprise as an standard, and a lot of them didn't follow the official recommendations when programming. Then you find how some old programs take all available memory for its task(even on an 1MB or more, on an expanded EP) and don't release it at exit.... This is not a problem if you switch ON/OFF every time you run a program, but the Enterprise was created as a multi-session computer, even there are some tasks that can be stopped while doing others.

Other programs take the Ram without asking EXOS or use forbidden memory zones, making the system crash when the control is returned.

It has been only on actual times(quite some years now...) that Zozo has impulsed a standardization on programming, returning to the old official rules, what, added to his modified/fixed EXOS Roms, has brought us a more usable and enjoyable computer.

The previous chaos explains why there are only a few programs that can really benefit from more memory. But don't forget EXOS as the main beneficiary of more memory, because a lot of extensions can be loaded on Ram, better and bigger Ram Disks can be created, Roms can be emulated, etc.

Somebody has cut that strip.

Just the point gets crackled on time, and a way to recover the membrane is to cut some millimetres.

Yes, amazing. Kyp only has implemented  TEXT 40 and GRAPHICS LOWRES 256, necessary for booting EXOS, show the flashing letters and start Basic, but it seems that it can also show HIRES, TEXT 80 and other colour modes....

Attribute? I think still not. But Ron once loaded part of a screen with a lot of colours... It can be.

Probably you have noticed that only 8 colours can be seen on the 256 colours demo... This is not a defect of the core, but from the ZXUNO FPGA device, intended to manage the Spectrum core. Soon the team will port the Enterprise core to other more powerful FPGAs.

Other aspect was that a lot of programs failed to load, but I think that it was due to lack of Ram space. Kyp says he will add more on the next update.

As a proof of concept I think it is very impressive.

You must grip a strip with the two hands, two fingers each(thumb and index), very near of the tip. Then position the strip on its place and press down firmly on the connector.

The clue is to take a very short portion of the strip, so it not bends while inserting it.

Not so long ago Tutus was honoured to ask Nick Toop some questions.

On his answer he narrates how painfully was his exit from Enterprise Computers LTD:

".....when I was constructively forced out of the company was one of the saddest periods of my life and I do not like to think about it.  I was also obliged to erase all personal copies of the design which is sad as I had various enhancements in mind and would love to be able to implement my design with these enhancements in a modern CPLD...."

This mean to me that all people involved on the project had such obligatory clause in their contracts.
