OK, before we moved to a new house (yeah, nothing good ever starts that way), my IIsi was last booted around 3 years ago. it has a 40MB Quantum ELS in it. Kinda got tied up with other stuff. Now, I'm ready to sort thru some 100 Disk Doubler-ed floppies and it won't boot.
On startup, I get a Mac icon with the ? in it. Boots fine with a floppy. I hear the Quantum spin up. It makes a whining sound, so I was thinking maybe a bum HDD.
Following prior postings, I replaced the PRAM battery and reset it. It's keeping time now, so I know that's working.
Tried my 1GB Jaz drive (the only other SCSI device I had at the time) and it wouldn't boot from it. However, the access light on the Jaz blinked rhythmically, like it was being polled. I double checked the SCSI termination, even replaced the stock cable with another with a terminator on it. Still doesn't boot from it. Just blinks regularly, like the bus is being polled (which I guess it is being SCSI, right?).
Just got a new HDD from EBay yesterday. 2.1GB IBM. It spins up too, but has no whine! There is a longer pause, but still can't see the drive when booted from floppy. I have a 6.0.7 boot floppy that has the 7.3.5 (or is that 7.5.3) patched HD Setup on it. Says device isn't found. I have downloaded but haven't copied over some other SCSI utils to test that I have the drive on the right SCSI ID.
It starts up fine from floppy and I can move the system to a ram drive, so if pressed, I can make do and get my files expanded properly. But I really grew attached to having a hard drive!
So, since I've tried multiple devices, I thought maybe it's a blown capacitor. I have no goo on my board and all the caps look (to me at least, and I'm even less than novice) fine. No bulges. No scorch marks on the board either.
At this point, I'm thinking the SCSI connector is hosed up and I was thinking of getting a DB 25 - DB 50 adapter to plug the hard drive into the external SCSI port. Is that a good "next step" or should I check/look in another direction first?
Thanks in advance for all help!
