You're right, that does look like your standard AT keyboard and Logitech 
mouse.  I tried an AT keyboard just a couple of minutes back and it's 
close, but it doesn't work properly.  The keyboard LEDs cycle while the 
2030's running its (very lengthy) diagnostics but once I get to a 
prompt, I get gibberish from it -- looks like the keyboard scancodes are 
completely different.  (Just for fun I tried an XT keyboard and that 
doesn't work at all...)

It does give me a place to start hacking, though...

Thanks!
