I'm having fun playing with (currently) low-cost
SlimSCSI cards in laptops and it's going well.
I've made some outrageous kludges
PCM card -> HD50 dongle -> HD50 ribbon -> adaptor -> IDC50 ribbon -> drive
kinda things.
They worked but I'd really prefer something like
PCM card -> HD50 dongle -> adaptor ->
   DB25
   IDC50,
   HD50,
   HD68,
   Untra4 device...
Anybody have a supplier to reccomend?
