- Vintage Computer - Soviet - Russian PC a look inside
Daves Computer Blog www.microcomput...
David was given this computer in Ulyanvosk Russia 1991 www.kk4ww.com
A number of members of "Foundation for International Radio Service" (FAIRS) traveled in the Soviet Union in the 90's. During one of the early visits David & Gaynell Larsen (KK4WW KK4WWW) visited Ulyanovsk Polytechnic University (UPU)in Ulyanvok Russia to teach a computer workshop & sign exchange agreement with Virginia Tech (VT) & UPU.

It was during one of these first visits to Ulyanovsk that this computer was given to me by the president of Ulyanovsk Polytechnic.
We made 3 or 4 visits over the years teaching and operating amateur radio. This mission visits resulted in at least 12 or so officials from Ulyanvosk Polytechnic doing exchange visits at Virginia Tech in Blacksburg, Virginia.

Here is some information from Ed S about his thoughts about this computer - Thank you Ed for the insight - great info. I should have known it was a clone as the Soviets were good at that - Glad to have this in our museum Dave KK4WW

It's a Delta-S (Дельта-С) a Spectrum clone - the multi-function keys are characteristic of the Spectrum keyboard. In this case there's an additional mapping, of Cyrillic characters. Therefore not precisely a clone, but an adaptation.

This is more the Machine Code class computers used for learning computer control. Such as for street traffic lights and breadboarding for engine controllers.
There were PC clones available and these were REALLY good compared to what school kids had in the West. I got to use Amiga 500s and I wish they had cloned these and upgraded the build. In the Baltic States we use the Latin alphabet so when the later Amiga 1200s arrived in 1991 - 92 we thought it was fabulous. We got lots of machines fully developed with masses of second hand units available lots of addons and a massive library of software.
One person went to Scotland and discovered the "Barrows" market place in Glasgow. It was a hotbed of piracy and slightly illegal tech. Like something out of a 1980s cyber punk novel. He bought a huge number of soft ware disks and some hardware as well as the people selling simply giving him things for nothing.
With all this material from Scotland and discarded Soviet military equipment we were able to hack satellite TV pay systems and even the international phones. I can only imagine how this helped the development of business and the government during very hard times.
1:22 From right to left: Joystick 2 and joystick 1 ports (for sinclair joystick), cassette recorder input, power connector (+5 V), rgb display connector, reset button, and next three holes are tuning resistors for display colors.
The two white chips is a BIOS, the ultra-violet erasable ROM. Ft the 3:11 at the middle of the screen, two chips row is a RAM. The right one (as I remember) is a video RAM, and the next one is a CPU-RAM. The rest of the chips are system logic. Delta-S has 16Kb ROM and 48Kb RAM. The first 16Kb use 8kbit chips and the rest 32Kb use 64kbit chips. But there chips are discarded. (As I remember again). One dot - half of volume available, two dots - a quarter of volume.
Any chance to get a video of your other homemade soviet/russian machines? I really like those - even built my own Pentagon 128 (roughly 90 dip chips and a lot more useful than the original Sinclair made ones) in 2013. The russian ZX community actually is pretty crafty - you can get replicas/schemes/pcb designs for almost every model easily or go with newly designed modern FPGA/CPLD based machines.
Hans Meier Hi Thank you for the comments - I have a few more homebrew early Russian microcomputer. Dave www.kk4ww.com
Hi Ed S - Thank you for the info - I should have guessed it was clone -
That is a ZX Spectrum clone. Like all ZX computers, this one is optimised for programming in BASIC, such that nearly all the statements in the ZX BASIC are accessible by pressing one of the labelled keys. In practice this did confuse new users, but it allowed very quick input of common commands. This computer has an extra function not available on a real ZX Spectrum, that of a Cyrillic character map, which is accessible with a single key.
+douro20 Hi great information. Thank you. Where are you located ?
We are moving our entire collection to the Computer Museum of America in Roswell, Georgia.

Kansas.
Of course the keyboard has Latin. How would you write a program in BASIC or Assembler without it? (The bottom right button is a layout switcher.)
I grew up on this machine, one of the best speccy clone, if you need any translation done let me know, the diagrams show how to connect this to your tv, you have to open the back panel (and risk being killed by high current) and build or buy and install an RCA like module to actually connect it to soviet tvs
Hi Thank you Roman for the offer to help. David
@@lcfgroup No problem, thanks for making this video, really brought up some childhood memories, th-cam.com/video/7Zf9xe53hEg/w-d-xo.html if you look at the top left corner it says RGB but ground and sync are in russian
Бабушка на таком кодила :D
Note how at 3:51 the dollar signs are hand drawn into the manual. Sorry comrade, but we can not typeset this capitalist symbol.
Nothing surprising: most probably, they really couldn't.
(I have no idea, how this manual was typeset. But, probably, with some bigger computers, like SM-series.
All of them used KOI-7/KOI-8 encoding. Yes, dollar sign was replaced by generic "currency sign" there.
Probable reason, why it was hand-drawn.)
Looks more like s Soviet Fairlight to me
