I have an Ampro Little Board Plus that's been sitting in a box since Dave Baldwin gave it to me some time ago. Tonight I finally hooked it up to a power supply, drives, and a terminal and whaddayaknow...it came up just fine, once I got the drives, jumpers, power supplies, cables, etc. sorted out. Not a huge project but something to keep me busy while I'm collecting up parts to get the Ferguson BBI he gave me set up properly (how I wish I'd subscribed to MicroC earlier, now!)
The long version is on my blog.
Anyway, now I want to get a hard disk on it. The docs say it'll use anything SCSI up to 88MB. My low capacity SCSI drives are already spoken for in other systems. I've got a couple of old ST-506 MFM drives of about 40-60MB that are free, I could probably find an Adaptec 4000 or something, but it'd be nice if I could do with what's on hand.
So, the question is, can I use a SCSI hard disk larger than 88MB and what would it take to make it work? I have plenty of other SCSI-1 SE drives around. Frex, could I put in a 120MB and just format it for less? Or could I edit some constants and format the drive then?
As for buying a small SCSI disk, the ones most plentiful on the net are old Mac drives. I seem to recall there's something different about the Mac SCSI controllers--changes in the standard command set or something. Or do they implement at least the required SCSI commands, enough so that I could expect to use them?
Your thoughts, suggestions, experiences are welcome.
Thanks,
Mark
