Hey guys,
So I'm trying to revive this 1040stf, but so far having no luck. It's showing three bombs on boot up & rom test showing failure cs failure on H1 chip. I replaced all TOS 1.0 roms with a known working set also 1.0, but getting same results. Are there any clear schematics of a rev D board anywhere or anyone have possible ideas for next steps?
Thanks!
