A colleague of mine has a similar problem.  The drives involved are a
Conner CP-344 40MB and a Seagate ST-1144A 125MB.  The drives work ok
individually, but we haven't discovered the jumper settings needed to get
them both to fly at once, and we are loathe to experiment and possibly end
up toasting something.  The jumpers on the Conner are labled HSP, C/D, DSP,
and ACT; the jumpers on the Seagate are ACT, EVS, SLV, MTR and LT.  Anybody
got info on the proper configuration for running both drives?

This is pretty esoteric, so I suggest you use e-mail rather than posting
to respond.  Thanks in advance...
