Eh Hayes, Hayes...

Ooo! So this is All himself online!

Hey, iron people! There's a problem here, I just don't know what to do...
The situation is this:
There are two Spectrums:
1. Leningrad1 updated to Pentagon512
2. "Clean" Pentagon128 (board with integrated YM)
And there are two Momeds:
1. USR Sportster 14.4 Fax \
2. Some kind HMD-2402P for 2400 / Internal of course
Both computers contain the same Shepelev circuits for connecting the momed + buffer
on AP6.
Result:
comp1+momed1 - works
comp1+momed2 - works
comp2+momed1 - works
comp2+momed2 - DOES NOT WORK AT ALL, i.e. same as without momed! :(

The food was served correctly. WHAT COULD THIS BE???

With best regards, Yuri Voynalovich.

Greetings, Yuri!

The length of the wires, their location, the type of AP6 microcircuit can have an effect.
Its analogue - 74F245 works better.

Wow! The Protoss are attacking my Zerlings! It's time to get going. Ivan.
