So I have a Ross related question.
I have a 4/690 in the build-lab that has a Ross 100Mhz chip in
it, working fine. (pk used it to do the hypersparc support).
We recently acquired a 150Mhz Ross (626) in an SS20. It works fine
there but putting the cpu in the 4/690 in place of the 100 doesn't
work. The mchine doesn't come out of reset and all LED's stay
on. What am I missing?
