Okay, I know this topic has received quite a bit of cover already, but I didn't
pay attention...
What is necessary to get a 3.5" drive to work on a PC/XT? Here's what I have
now: IBM PC-1 with 64K on mother board, a couple of AST SixPak's, an IBM
floppy disk controller driving two full-height 360K drives, an Expansion Unit
with two ten-megabyte hard drives and the appropriate old-as-the-hills
controller. I'm running PC-DOS 3.2.
The floppy controller has a connector on the back for a third drive (and I
believe can handle a fourth as well). What I want is an external 3.5" drive
that I can plug into my existing controller. What I expect I'll have to buy,
though, is another controller. Any help?
Please send e-mail to qintar@agora.UUCP.

That's correct: You'll have to buy another controller. If you're
willing to sacrifice one of the 5.25" drives, you can get a controller
from JDR Microdevices that ought to work. If you want all three
drives, consider the Compaticard controller from Micro Solutions,
DeKalb, il. It can handle 8", 5.25", and 3.5" drives, high and
normal density. The cost is $ 175.

If you're > Mike Berger No. If you want a 3.5" 720K drive, IBM (among others) sells one that runs off the existing floppy controller. I've got one. The only requirement is that you have DOS 3.2 for the DRIVER.SYS device driver. However, if you want a 1.4 Meg microfloppy drive, yup, a new controller is needed. -- dan davison/theoretical biology/t-10 ms k710/los alamos national laboratory los alamos, nm 875545/dd@lanl.gov (arpa)/dd@lanl.uucp(new)/..cmcl2!lanl!dd "I think, therefore I am confused"

With my old PC-1 I installed a 3.5" drive as drive C: by soldering a ribbon cable to the appropriate pins on the (inside of the) rear panel connector of the floppy disk controller. It took some time to figure it all out, and I used a bus wire (16 gauge, I think) bent in a hoop to solder all the ground wires to. The other end of the ribbon cable was terminated in the appropriate connector for the drive; it worked and I was happy with it. keith
