ATM TURBO connoisseurs, respond!

Here I took out the memory from the disabled topic. Explain how (if possible) instead of
565RU7 to plug into the miracle computer ATM TURBO (not 2) if anyone knows, or describe the legs
MCM6256AP15 is 256x2 (right? 2 inputs, 2 outputs?)
MN4164P-12A is probably closer to RU7 (or 5).
Instead RU5 seems to both work Zh8).
If they are not analogues of RU7, then how much modification does the circuit need to do in ATM in order to
adapt? (as they say, maybe it’s not worth it?)

Another question for the “experts” - how to eliminate the stuck
WAIT signal in this board (it turns on and everything stops) on the Z80 with the turbo on?
Board ver 4.50.
It would be nice to finish it (wishfully so...).

I don’t know about these - but maybe Ru7?

And this is 100% Ru5

Look at what is being slowed down, if the ADWT signal (2nd leg D75) see the ADC selection circuit
(or take a bite and apply +5v if there is no ADC), if not see if the RCR signal (1st
D71) is reaching, well, replace D71 as a last resort.

Bye! It was nice talking to Devjatkov!
