I’ve lurked here long enough. First of all, I am grateful for any and all help and information I receive in advance. There is some excellent knowledge here and some talented people and I hope I can learn from some of you. Okay.... on to my issue. I recently acquired a lovely Mac Plus from the widow of a fellow who passed away a few months ago. I got it home a week ago and it booted up beautifully... it has two external SCSI hard drives which both contain an unbelievable amount of history and richness— I hope to archive these if possible. Fast forward to today... I plugged it all back in after relocating it upstairs to my office, and it will not boot up with the hard drives... I tried multiple trouble-shooting techniques, attaching only one drive at a time, allowing longer spin-up time, etc. Each time, and with both drives—the drives spin up, show green lights, perfect. When I turn on the Mac Plus, the screen comes on for a moment, then it turns black and the hard drive light turns to red. And then that’s it. I can boot from floppy, but my Mac Plus does not boot from the hard drives now. Instinct tells me that there is something wrong either with the interface cable (unlikely) or the SCSI port on the Mac itself, but I took upmost care in transporting the Mac and components to my office. Do you guys have any ideas? I tried to post pictures, but they seem to be too large. I will try to resize tomorrow.
