Where can I find informations about ZX BUS used on russian ZX clones ? Pinout is same as on original ZX Spectrum BUS ? :v2_conf2:

Now the ex Soviet Union standard ZX Spectrum bus - NemoBus. NemoBus - is a modified bus ZX Bus. NemoBus - this is not the Russian standard, this standard ex Soviet Union. NemoBus used in all computers KAY, Pentagon-1024SL v1.4, v2.2. A computer Scorpion ZS256/Turbo+ is not used NemoBus, there is clone ZX Bus. The main difference NemoBus of ZX Bus - the existence of arbitration. Slots NemoBus not the same, highest priority is the 1 st slot, the 3rd slot is the lowest priority. To work NemoBus are most familiar to the original scheme of computer KAY-1024SL:KAY-1024.rar

This is very similar as original ZX Spectrum BUS :v2_rolley
Pinout of main signals(from CPU) is same. :v2_thumb:
You can connect interface designed for original ZX models to russian ZX clones with this ZX bus layout.

You can connect to russian ZX clones:
- my K-MOUSE TURBO interface (compatible with russian wheeled kempston mouse)
- DATA-GEAR (DMA)
- SAA1099 interface (sound chip from SAM COUPE)
- DivIDE interface (use extra rom+ram, ide ports, systems with FAT16 support, TAP, SNA, Z80 loading....)
- MB02 interface (DMA support, external memory rom and ram(512kB),rtc,8255)
And I can connect to my original ZX128+2:
- GENERAL SOUND
- Z-CONTROLLER
- ZXMC
Electronic circuits connecting SRAM exist, but there is no single standard. For the clones ZX Spectrum ex USSR is not necessary to have an SRAM, as they have large amounts of RAM. In addition bus NemoBus allows external devices to connect external memory in address range #0000-#3FFF.

Смотрю я на этот ваш зхбас
и что то больно он похож на разъем для картриджей от дендика
(которых у меня лежат мертвых 3 штуки)
не оно ли это?
вроде бы тоже 60 pin 2.54 шаг
можно их задействовать в спектрумостроении?
хотя беглый загляд в доку блеккета
говорит что там 62 пин-а о_О
на куче фоток 60 пиновые... о_О
