Boots and gets through the Ram test screen but then just sticks there and goes no further. Any CSP1 guru's out there?

What are your Power supply voltages at?
Can you check under load off the jamma edge?
Are the 3 stacks mated correctly? 🤔
 
The voltage is at 4.95 on the edge connector, the 3 stacks appear to be mated correctly.
 
Check for physical damage on the PCB; I had a B board (middle) that had a resistor broken off and hanging, this caused a similar issue. (the resistor is a setting for which eprom type the board uses, being broken it was unable to read the program code)

Adjust it to 5.01 and also follow Duffcons directions. I'm betting it's voltage as some cps1 boards require a clean 5v.
 
Could be a brocken trace or a program rom socket problem , in my case my champion edition was getting to the ram test screen then resets , after replacing the sockets for the program Roms it did the trick and now it boots every time with no problems
Ps: the original sockets looked clean but they were making the problem

It could also be one of the pals ( IOB1 & the one next to it ) try replacing them it also might solve your problem.
