Or the best version of all, i.e. one you can 'snap off and throw away'
like Windows 1/2/3 on DOS.

For my new data-reading system I've cobbled up, I have it running
Windows 98, but tweaked it to not boot to Windows at all, just wait at
the command prompt.  Then after I've created images and what-not, I let
it go the rest of the way in so I can copy the image files created over
the network.

I don't have a 486 system up and going for these purposes mainly because
at present I sit at a 'console' that is a 4-way KVM switch, and it's
simpler just to plug everything into this one desk.  Most '486 systems
use the older non-PS/2 keyboard connector.  (adapters are available,
etc. etc.)

It's 'convenience' and 'using what is lying around' that is the root of
this whole thread.  A more sensible person would stop messing with
systems that only support one floppy drive.

I can't think of anything at all where XP is the suitable choice.  Well,
maybe a preinstall where the manufacturer has not gone out of their way
to provide driver support for anything else.
