Re: It's ROM 1.02; more symptoms; can anyone comment?

Wow. That would never occur to me. That short cable between the board and 
the CPU socket? It's about an inch long and seems innocent enough. Where 
would I purchase a better cable or the parts to replicate the cable with 
better materials?

More information: The IIgs was crashing a lot with 12ns tag and 20ns RAM. 
I'm now running fairly stably with the 20ns 32x8s in tag and the 70ns 32x8s 
in data...albeit only at 8Mhz.

I'm not ready to give up yet. I'd like 10Mhz or more. If anyone else has 
recommendations, I'm all ears.
