Wow, that close in zoom and pan brought back the MEMORIES! I remember stroking my fingers around those curves back in the day. I can feel it now after seeing that! Oh the "RESTORE" key .. I had forgotten about that one!

is someone else from bg watching this?

Lovely subject Thank you v much Sir

I own dozens of New - Old Stock CM630P ICs, with a number of them being used in a number of projects.

yep. I bought a bunch of 10or more some years ago, since they were quite cheaper than the 6502 at that time. I used them in some VIC-20, at least one 1541, and some PET (2001/N, 2032, 8032 etc.). They work absolutely fine, I've never had any problem. Not sure if in some extreme circumstances they can go wrong, but until now I'm totally satisfied, and I'm saving the original MOS 6502 for future needs.

This was fascinating, I would like to know more about eastern block computer science history.

Ya great video…thanks for posting

heh, Ivan Marangozov, there used to be a joke that ИМКО-2 is a capitalisation from the bulgarian for "Ivan Marangozov Copies the Original ...second try", "Иван Марангозов Копира Оригинала... вори път". IMKO-2 machines were renamed to and more popular under the name of Pravetz 82, clones of Aplle II as mentioned in the video

From around 4:13, there seems to be artifacts around the large numbers on the clone screen that aren't there on the genuine screen. Are you able to re-run the demo on the clone system and confirm it's not just me that's seeing it? (could be video compression artifacts during upload)

Nice job showing us this Soviet Apple II clone!

4:13 - random pixel is blinking on the left of numbers and also some above numbers. You can see it even earlier, but it's not that visible edit: noticed somebody already mentioned it and got answer, same time, scroll down

Did you run something that uses opcodes? Like some test for emulators? This would be more interesting than this :)

As the clone CPUs are 1:1 copies and not remakes, they include even all the mistakes that were made in the creation of the original. They include all the illegal OPs, have all the same timings and are thus more compatible than a 65C02.

As I was a kid back then when that clone was produced in Bulgaria it is really hard to find honest information about the technology and how they copied it but the fact is they did manufacture it somehow and it is unclear who were the people who did it. There are some engineers claiming this was their baby but we all know it can't be only a bunch of people involved, probably some samples were bought from the USA and brought illegally for examination thanks to the Intelligence back then.

They copied the masks. And they must have had help from the GDR to build the process. Never forget that these were second world socialist countries without the type of infrastructure found in the first world.

Not entirely true. The early ИМКО machine used Taiwanese 6502 clones. Bulgaria was part of the Eastern Block, but it was it was doing business with Western European countries too. Not much with the US, though. AFAIK BRD (West Germany) was one of its main economic partners. Many institutions (and even some elite high schools) had original Apple computers and original IBM PCs. The majority of the computers produced were exported to the USSR. As someone else mentioned, Bulgaria used to make Apple II clones (many variations, some quite different from any Apple-made machines), an ORIC Atmos clone (Правец 8Д), IBM PC/XT/AT clones(Правец 16, ИЗОТ), original designs (Пълдин), Z80-based machines (ИЗОТ).

@@TechJump Unfortunately decap is not really a suitable way to copy. It does resolve a lot of reverse engineering ambiguity though which is why preservation communities do this today, they can extract the structure and the mask ROMs, but essentially the whole thing needs to be re-engineered if all you have are dieshots.

My first intro to computers I remember saying this straight Garbage. Then I met my the love of my life nes Nintendo. To me a computer just tool like screw driver or hammer. I once throw brand new laptop in dumpster because there was no sound on KZread. My reason was it's going cost me to much time figure this out. Mother board to me looks like Google maps air view or tiny city.

If it worked differently, it would not be much of a clone, now, would it? ;)

clone or whatever it just prosessor that have same op codes. yeah clone but could be diff. and 6502 nothing todo with graphics. even clone 6502 it would not look same if graphic card is diff. so this is computer clone. not 6502 specific

In this case, it is only the cloned CPU. Pravetz never made clones of Commodore computers. Pravetz did however make clones of the Apple II, Oric Atmos and IBM PC XT
