Thanks for the info, I'll see if I can track down a compatible mouse.

And scratch what I said about the keyboard -- recalling that there are 
"standards" and then there are "standards" I grabbed a different AT 
keyboard from the shelf and tried it, just in case.  And it works 
perfectly.  So, it's a "standard" AT keyboard, but be careful which one 
you choose :).
