I build an interface board between the BBC 1MHz bus and the SCSI
(actualy SASI) interface. I tested all functions and it seems OK. The
only problem I ran into was finding a SCSI-drive which would format at
256 byts/sec. All drives I own don't support it, not even through quite
advanced formatting software on my Macintosh computer.
Most drives come from a macintosh and are between 20 & 1024Mb in size.
Someone suggested (here?) to use a Syquest drive, which I did not test
yet. So I like to oppose the idea that almost every SCSI drive below
500Mb would format in 256bytes/sector. If anybody had succes with a
SCSI drive on a BBC, after reformatting it at 256bytes/sec, I would
really like to know its type & make. (the drive of course, not its
owner)
Thank you very much.
