I was given a nice apple IIe and amber screen kit (no drives or anything tho, but the machine itself is working great. It's my first vintage apple.

I was also given... this. I didn't notice any identifying marks anywhere on the board. If anybody has info on this please let me know:

There are some notes, a parts list, and also a partial photocopy of a schematic, etc:

Judging by the list of problems, and also the fact that the roms have no window covers (they were also sitting partially in the sun all day as I had left my hatchback open most of the afternoon, it was in a translucent bag) I don't think it is currently working. Think I have a chance at getting this working? (of course, all the chips are socketed, the tricky part would be to find the proper ROM image and have it written in) Are these clones/knockoffs even worth anything or interesting from a historical perspective? Blue happens to be my favourite colour, btw ;)

Update: See the Unitron name around coordinates D8?
Wikipedia wrote:
Unitron, a Brazilian company, produced another clone, named ApII. Unitron used a copy of the Apple's ROM translated to Portuguese. The operating system was Apple's DOS 3.3 translated to Portuguese. During this period, it was illegal to import microcomputers in Brazil, and buying those (illegal) clones was the only way to have a microcomputer. Unitron stopped manufacturing the ApII a few years after the introduction of IBM PC clones in Brazil.
Is this an ApII mainboard? It would be pretty hip to get it working with the translated ROM :mrgreen: It looks like http://www.museo8bits.com/unitronap.htm#E/S

I remember reading a Byte article many years back where the Russians had cloned the Apple II.

If you need Apple II ROM images, ReactiveMicro has them on their website:

http://www.downloads.reactivemicro.com/ ... /II_&_II+/

They also offer them burned to physical ROMs if you aren't in the mood to do-it-yourself.

Your apple clone is from the taiwanese unitron, not the brazilian branch. These where independently manufactured. Taiwan unitron used that distinctly blue color in their boards.

What you're looking for is unitron U2000 roms

I found an article that mentions that there are in fact two different Unitrons here: http://www.applelogic.org/UnitronAndI.html

I can probably chase down an eprom burner.. Thanks for that site Neko, it looks like a lot of fun! (they have all the manuals too, which I needed but hadn't had the time to look for) :)

Well. The guy who gave me the apple //e found a box full of apple //e stuff. So I got a disk II drive (complete with installation kit, cable clamp, the screws, the wrench with the apple stamped in it, the books, the stickers, dos 3.3, the welcome to apple demo, etc)

I also got a couple boxes of fun games, and since the guy is the IT guy at our school there were a couple old disks from some of the greybearded professors. so there are a lot of cool little programs like characteristic polynomial root finder, partial fraction expansion, antenna calculations, logic simulator, etc

trying to decide if I should go back for the printer or not. At least, I really like "snake byte" :)

I also got all the books for the apple, so now I can learn to use it :P

There are lots of great Apple II resources out there; it's pretty easy to hook up an Apple II via serial and send downloaded disk images via ADTPro. You can also back up those disks you have to your PC/Mac for safekeeping: http://adtpro.sourceforge.net/

If anybody wants to see pictures of the machine, you must go here
https://www.facebook.com/media/set/?set ... 969&type=1

I figured there would be nothing too exciting, I mean, everybody has an apple II! but here we go.

Very cool! It's always nice to see how others have their retro computers set up. I'm working on a new desk arrangement in my spare bedroom for my older machines and will post some pictures once I get it all together.

This machine has reached it's final resting place in the ECET stockroom at school, there are some disks loaded up with a bunch of games and a little note saying how to get it going. So somebody can enjoy it.

I still have the unitron..
