Re: Forgottenmyname - Progress
Channel one yellow is /AS blue is /DTACK
It is looping as Troed says, the Newb in me hasn't worked out why yet but once we have, I think we'll be right onto the bombs step again.
P.s. not learnt how to do screen captures on my scope yet.

Re: Forgottenmyname - Progress
4V does seem a bit low oddly, should be near 5V really... what do you get on the power pins of LS11 ?

Re: Forgottenmyname - Progress
My PSU needed a quick tweak, was running at 4.93 between 7 and 14 of the LS11 which was the same value on the floppy power connector
