Yep, I was obviously thinking of the non CRTC machine and forgot to double check the machine I was posting on.

Get some 74LS244's to piggyback UB4 and UB6 since we are not sure if it's the even or odd part that is bad. Also get a 74LS373 to try the UB3 latch.

Piggy-backing TTL chips can sometimes work - but in my experience I have little luck with this technique (unlike RAM).
