[comp.sys.ibm.pc.hardware] Leading Edge Model D - HELP!!!

Bill_von_Hagen@TRANSARC.COM (12/11/90)

I have an ancient Leading Edge model D (integral video and floppy
controllers) to which I'm trying to add some more modern peripherals.
I installed a hard drive with no problem, but I'm now trying to add
an external tape unit, and can't get it to work!  The story so far:

The tape unit has its own controller which is supposed to be daisy-
chained between the floppy controller and the floppy drive.  When
I put it in place, the software can't find the tape drive.  Next,
there's a jumper on the motherboard that, if removed, is supposed to
allow me to use a different floppy controller, from any slot.  However,
when I pull it and add a new controller, I get a "Disk Bad" message
at boot time.  I've tried to swap in two different controllers, and
have gotten the same message, so I doubt that the problem is in the
controller.

If anybody has any experience with one of these, please contact me!!!
I have a tape backup unit and a high-density drive that I can only use
for paperweight until I resolve this.

  Thanks!
