IBM 3290 terminal

Imaging the thing will be extremely tricky; the 3174 uses 2.4MB
floppies which I don't think are used *anywhere* else; you can't just
pull the drive out of the 3174 and throw it on a PC because the BIOS
won't have a clue about 2.4MB 5 1/4" disks; people have tried that
approach before. And the code doesn't allow you to format a blank
floppy; you have to use IBM pre-formatted disks. You can copy the code
from one disk to another.
But the easiest way would be to do what Guy has done; take a 3174 with
a hard disk and replace the disk with an MFM emulator. You *can* copy
the 3290 DSL code from a floppy to a hard disk and run it from
there... does your Memorex device have a hard disk? If not I would
suggest obtaining a 3174 with a hard disk as a first step; they're
relatively plentiful and cheap and you WILL want it to avoid dealing
with the hassles of flaky floppy hardware. In fact I would suggest
obtaining one anyway; no reason to mess around with a non-standard
Memorex when 'everyone else' is using real 3174s...

'No greater love hath a man than he lay down his life for his brother.
Not for millions, not for glory, not for fame.
For one person, in the dark, where no one will ever know or see.'
