I have an MV2F that has a few issues. On both slots, I have graphic issues:
And on slot 1, I have no sound.
Diag BIOS shows no faults, so ok there. When using a CHA board with a diag M1 ROM, it shows I have a Z80 comm issue. I've checked and confirmed all traces listed on smkdan's website - D0, C0, and Z80 lines are all ok. No issues there.
I can't find any issues over on the 257s - there was two bad traces that I repaired, and other than that, everything is checking out ok continuity wise.
Any suggestions on where to look next? Is it possible the Z80 is dead?
