Thought whilst changing over SIMM I would post pics of the extended headers that allow the Exxos RAM card to fit.

Yes, I still have sync issues on my CRT, i've got a rolling yellow screen (think my blue wire is stuffed)
I still have 60hz out of 38 on the glue as well as 15khz out of 37.
I've no longer got /AS cycling, its just low now. Have some pulses on R/W on power up and then after about 10 seconds that drops to 0 if i remember correctly.
Pulses on the MMu to the memory but nothing from the rom so far, so thats the problem in my case I think.
When I got it to bomb I was scoping around the rom.

Do you think we should start an individual thread each?
