i am exchanging the board with Andrew , as the traces are very fragile, and messing with it to much might make things worse and to a point no one will touch it. i have ordered everything i need for the monitor and will put my efforts there and a freshen up of the cab and a closer inspection of...
Was probing a bit today , A2 was as far as it would test , prober B4 M2 , pins 1,2 both has some activity, went to F2 . Pin 2 was dead . Held probe to pin 2 , hit reset and pin 2 (F2) went low then high and A2 passed test and Hanging test on A1 now. I think F2 is no good.

i bought a 40x illuminated magnifying glass today, i think i may raise them with thin stock cardboard just a wee bit . im going to clip and remove one leg at a time, i assume these are just as fragile with lifting as the williams boards are. toning out is a great tip , will do. im going to...
done with piggybacking, tomorrow i will grab sockets. the original AR11 had a lot of repairs done to it and was super cooked in places, ill post pics tomorrow. looks like they went through that and stopped there. my hakko wasnt working very well so i took it apart and cleaned it,it works like a...
Ram is from a working tatio board, will start to socket and test tomorrow after work. as i piggyback one, the behavior changes. the only consistant one is J2. i had a sinistar that would piss around like this with the rom board and finally gave up and shipped it off, i think i sent it to you...
