The //c has both a disk interface and an expansion slot. Assuming the
SVD is even compatible with the //c, it must use the disk interface. I
presume this would limit the speed of operation to that of the original
drives -- something like 76.8Kbps, right? This is not fast by today's
standards, but would fill 64K of memory in only 8.3 seconds given that
there would be no time lost to seeking. With ProDOS, you should be
able to create virtual "floppies" of up to 16 megabytes in size as
well, right? This seems like a reasonable way to go for //c users
without an expansion slot.
While an interesting project it is outside of the scope of our current
development.
Well, once I figure out a suitable solution for //c video that doesn't
involve a CRT, maybe I'll dust off that old version of CodeVision AVR I
have lying around and see what I can hack together to emulate a floppy
drive, especially if the SVD project falls short. Always did like to
play with microcontrollers -- probably because they remind me of 6502
programming.
People seem to prefer SD cards over CF cards for storage these days.
But if the "virtual disk" was external and connected to the disk
interface port, wouldnt a USB key interface be more useful?
I take it that connectors for the //c disk interface port are not
available, so that the best way to get one is to buy a broken external
//c drive on eBay?
