Thanks for you feedback John. But no, nothings been added to the SCSI
chain - no cards, etc at all added during my system's long time of
deteriorating SCSI reliability.

My power supply itself might be finally packing it in. Its the original
one from 1983 or so. I've been considering getting a beefeyer (sp?) one
anyway, cuz I'm thinking of filling my last available slot with a 3.5"
controller card.

Where do I pick up a better power supply? Is it an easy process to swap em??

TIA again!
