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.
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.
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.
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. bugbookmuseum.blogspot.com/2016/01/bugbook-computer-museum-is-moving-to.html
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
@@lcfgroup No problem, thanks for making this video, really brought up some childhood memories, ua-cam.com/video/7Zf9xe53hEg/v-deo.html if you look at the top left corner it says RGB but ground and sync are in russian
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.)

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.)

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 -

Note how at 3:51 the dollar signs are hand drawn into the manual. Sorry comrade, but we can not typeset this capitalist symbol.
