I have a 128D which I was using with a lt. Kernal. Getting the LtK to work with the internal disk drive required cutting a pin on U3 and wiring to the daughter board. That was all well and good, but I decided to removed the LtK from the setup and when trying to resolder that pin (with a trace wire) to the board the damn thing broke off at the IC plastic.
Long story short, dead computer. So I pulled that chip, ordered a new 74LS08PC and put in a socket and all appeared well. Welp I'm still getting flaky behavior on file access (only in 128 mode) and I assume it's because the u3 chip is involved in burst mode and memory banking (who knows what else).
I'm gonna pull the machine and check my socket maybe the solder didn't float all the way through to the top of the board. Any other ideas?
