I just purchased an RT (Model 6151) and have several questions.

Question 1: Is the bus the same as an AT bus, in that could I use standard PC 
class cards in the machine?  I need to pick up a dual port serial card to
drive a modem and printer, and could get a standard PC card real cheap.

Question 2:  I also purchased two IBM Model 70E hard drives with no case,
and, unfortunately, no documentation.  I noticed on the Extended ESDI Adapter
I have in the system, which drives the existing 70E hard drive
and diskette (1.2mb) that there are two 34 pin connectors, and three 20
pin connectors.  Of these, one 34 pin connector goes to the diskette,
and one 34 pin and one 20 pin connector to the hard drive.  I've been told
I can use the other two 20 pin connectors to hook up the other two drives.
If anyone has done this, do you know the pin outs of the cables, and
what the power specs are for the drives (since I have to build my own
enclosure, with power supply, for the two drives).

Question 3: I also have a tape controller, with no company name on the card,
and again, have no documentation.  The only markings on the card are:
"BE 3-1 2386 EC A31257H".  It has a 37 pin male connector on the back.
Anyone have one of these?  Anyone know what it is?  Anyone still reading this?
If so, I need to know the pin outs for this cable, and whether this board
is a SCSI or ESDI controller.

A million thanks to anyone who can help....
