Спасибо. Схема альфа версии в первом посте.
Thank you. The Scheme alpha to versions in the first post.

And switching ABC / ACB

- possibility disable TS (only one AY)
- possiility disable SAA1099
- possibility set both AY chips as write only (reading is dangerous on machines with internal AY chips = data collision). It's impossible connect to real ZX Spectrums. But exist way - add resistors between data lines on connector and data on card. As on my K-MOUSE interface:

Об этом я не думал. Мне больше нравится идея с отключением питания.
About this I did not think. I more like the idea with disconnect and reconnect power supply.

Yes, this is better. But 100% correct way is software reset (or CPLD write values to registers)
