Good luck! Meanwhile, I'll try to get that blown 74123 out of my RX211
(output at pin 13 shows pulse, but inverting output at pin 4 shows no
move, and of course only this one is used) without damaging the board.
I suspect replacing the 74123 with a 74LS123 will change the timing? -
DEC apparently meant it to be quite precise: the capacitors are +/- 5%
types, the resistors even 1%.
