Okay, any IBM model M or Northgate fans who want to keep their baby
working into the new age of USB, go to radio shack and look for the
CueCat PS/2 to USB adapter. They're $10, which is dirt cheap. The only
other ones I've been able to find are integrated with hubs and port
replicators and thus big and expensive. ($60+) This I can duct tape to
the end of my M's cable for all eternity.

I can't find it on cuecat.com anywhere, so its possible all Radio
Shack's might not have 'em. I got mine at the Hopkins Mall location. (On
55, just east of 169.)

However a problem is becoming apparent, every once and a while a key
will stick down and keep repeating, until I unplug it from USB and plug
it back in. Though I have been having problems with my keyboard port
locking up until I reboot when hooked to PS/2, so it may well be they
keyboard. Or the HP barcode pen I'm using a keyboard extention because I
lost my ps/2 extention cable. I've unplugged it and I think that fixed
it... (I can now use a USB cable and hub as a cable extention...)

Anyway, M fans, or any other fans of an AT/PS/2 keyboard of some kind,
go get one while you can...
