View Full Version : IBM/Xebec Rev 3 Question

September 4th, 2017, 07:14 PM
I have a Rev 1 card in my expansion unit, so didn't help when I added a Type 13, 20 Meg drive to it. I have a Rev 3 card hopefully coming soon, question is, is it possible to have both a 10 meg and 20 meg on the same card?

It looks like you can.

Check out the Variation 3 docs here (http://www.minuszerodegrees.net/ibm_xebec/ibm_xebec.htm) (thanks modem7)

Switches 1 and 2 configure drive 0.
Switches 3 and 4 configure drive 1.

So, setting the switches to on, on, off, off will mean a drive 0 of type 1 (10mb) and a drive 1 of type 13 (20mb) :)
