'(OT) IDE Controllers for 8088 boards'

       Are there any companies that sell surplus or older equipment
that might sell IDE controllers which would work in an IBM XT or
clone?  I came across a bunch of probably perfectly good 40-meg IDE
drives and also have a couple of XT's that I use for communications
stuff that are in excellent shape.  A 40-meg hard drive would be a
nice addition to the system.  The controllers would need to look like a
conventional hard disk controller to the system and function as a
primary IDE controller.

       No PIC's here directly, but the old equipment is going to be
part of the tools I use to develop other things.

I think that you should try Jameco. http://www.jameco.com

Hi,

I'm afraid there is no IDE controller for 8088 boards. The XT did not
support the hard drive, so that the HDD controller cards (connecting to
MFM drives) itself have contained the required BIOS extensions. BTW I have
not seen any 8-bit IDE controller.

8-bit IDE drives are available.  Jameco would probably have them, as would
JDR.

               Yep, page 117 of the latest Jameco catalog.  ISA IDE
enhanced controller card.  Picture shows it to be a 8bit bus. $24.95

I've seen these surplus somewhere for less money, but am way late &
need to run;  Try surplus electronics & computer parts places (Might be
Hi-Tech Direct I saw these at last?) - these have a BIOS onboard,
specifically so that you can run the IDE drive on an XT.  Somewhat rare
surplus, $25 isn't bad & a warranty can be nice to have <G>

 I am sure the second claim is correct, but the board I have sitting
now on the desk in front of me, made by "V & V Systems" with an XT bus
connector, not one but *two* 39-pin connectors (pin 20 is absent as per
the IDE standard) labelled "1st-drive" and "2nd-drive", a 2764 BIOS
EPROM, 74LS244, two 74LS138, 74LS21 and 74LS04; tends to give the lie to
the first.

 And so do IDE controller cards!  BTW, this card also has a 5-pin spill
for power to each drive, and a jumper labelled "MINISCR WD" whose
purpose seems pretty clear.  It was made in approximately 1991 and is
"half-height".

 I re-iterate my previous mention that Tandy made a point of selling
"retro" machines with 8088/ XT bus and IDE drives around this time also.
I've got one of them here somewhere (blimey, what *haven't* I got?)!
