Thinking of that, I had actually wondered whether one could transfer the
appropriate image files from a modern PC (internet access) to a classic
PC (disk drives) using a SCSI hard drive. Not if the modern PC is a
laptop, I suppose.
I suspect USB-SCSI interfaces exist but I've not looked into one.
Adaptec USB2Xchange is one that kept popping up when I looked for
just such a thing years ago. Acquired one some time ago (from EBay,
because of course the product has been EoL for years).
Haven't used it yet, but it presumably works reasonably well.
Since SCSI is a 'formatted' interface it
shouldn't be too hard to make
pseudo disk drive using flash memory. I must look into that to make a
SASI drive for my P2000C.
There is a whole collection of SCSI device emulators out there and
they usually tend to use SD or CF cards for actual storage.
I suspect it's easier to use CF cards. At least
some USB card readers
can handle those. And the interface is essentially the same as the IDE
hard disk....
It helps that a lot of the pro DSLR cameras used CF as storage for quite
some time, so card readers for CF should be easy to find.
Kind regards,
Alex.
