 - Many thanks for the tip Liam re quote marks. Ive retyped the text -
hopefully this will work better.

Ibve been trying on and off for the past year to get a sparcsation 1 running

I finally (after replacing the CPU) have the board bbootingb slightly. It
shows the header message, but stops soon after with

0 bad serr reg0 bad serr reg1 bad serr reg2 b&.

I can STOP-A and get to a boot prompt, but obv. something amiss with the error

Ibve tried replacing all socketed ICs but still get the above message. Tried
swapping memory, etc

Its not something Ibve seen before. Any idea what this might mean?

There are no disks connected to the board, just PSU and memory fitted, with a
terminal connected to port A and a type 4 keyboard plugged in.
