Hi all, not sure if anyone is still following this thread but I'm hoping for some advice.
I have an SE/30 motherboard with dead SCSI (both internal and external). I've checked for continuity between all of the pins in the IDC header and the 53C80E SCSI chip - they are all good.
I've also checked the TERMPOWER and it's measuring 4.75 volts - is this within an acceptable range? If not, how could I get it to 5v?
Failing that, I guess the SCSI chip itself could be dead? I think replacing it is beyond me.
But also reading the post above by
@pbMacGeek17 he mentions broken traces to the SWIM chip - which chip is this on the motherboard?? Then I could test it.
Hope someone can help?! Thanks.
