I've been trying to extract the data off of a 20MB XT-IDE drive
(WD-93024X) that was once part of a hard card. It has the software
for my B&C Microsystems UP600 device programmer. Too many swaps
and not enough sleep later, I have inserted the card in backwards
(no bracket and it's an 8-bit card). It's now DOA. The Compaq
Portable II I'm using complains of an I/O ROM error.
So... I can check/replace any of the TTL on the card (74LS13, 74LS14,
74LS244, 74LS30, 73LS260), but the contents of the 2764 are possibly
lost to me. Does anyone have a ROM image or an old XT-IDE hard card?
The P/N on the ROM is 62-000352-031. The assy no. on the PCB is
60-000227-03, the P/N appears to be 61-000347-01.
No smoke got out, but it sure is unhappy.
Thanks for any assistance.

I may have a board out in storage. If someone else doesn't uncover one
first, I'll search though the boxes of controllers later this week.

Ethan, I have an Acculogic XT-IDE which is purported to be
interchangeable with the WD card that I can send you. The EPROM is
soldered in place, so getting the image is not straight forward.

That'd be great!
The EPROM is soldered in place, so getting the image
is not straight
forward.
Well... at the moment, I'm unsoldering all the chips that got hit by
odd voltages (about 1/2 the TTL for sure) so I can test them in my
TTL tester. I expect that the EPROM got whacked as well, seeing as
how -5V, +12V and -12V all end up on address lines when you insert
an 8-bit card the wrong way. :-/
There should be a way to save a block of memory to disk (debug, perhaps?)
from DOS, presuming you have a machine you can stick
the card into.
Still, the simplest solution is a board swap. I could probably burn
an image with my C-64 and a my Prom Queen if I located the software
to drive it. Alternatively, I have a serial-based programmer that
ISTR has an interactive hex dump feature - you talk to it over a
2-way RS-232 link and can dump data to it, or send interactive
commands. There's no "program" or "copy" button. It's a Bay
Technical
Associates 953B. Haven't used it in years. Think it only does 1Kbit
to 8Kbit devices and no funny pinout stuff like thge 2532.
Thanks to all who have offered help.

The card arrived today. It is a 100% knockoff of the WD card, the
biggest difference (besides the copyright notice) is the WD card has
a very smooth solder mask and the Acculogic has a pebbly one. It
works like a champ!
I also just got my Ming HT-21 handy tester back. The 74LS260 next
to the external power connector is fried. The other TTL test fine.
Don't know about the EPROM yet... will test that after I extract
the application from the WD98024X drive. Kermit (for non-obvious
reasons) chose to not preserve files when sent over an NE1000 to
my SPARCstation in binary mode, so I will be backing this drive up
via 1.44MB floppies and cutting a CD-R.
Thanks to all who helped and offered to help, especially Don.

Might not help any, but I've got a 16-bit 105MB Plus hardcard that you can
look at if you want.
Thanks for any assistance.

Ethan,
What brand of HardCard was it? If it's a real HardCard I think I have spares.

A real Western Digital Hard Card 20 with an XT-IDE (not MFM or
discrete signals)
I just discovered that I _really_ want to get this up600 working
again - it has DRAM/SRAM/TTL/CMOS test mode, too. I never knew it
did until I saw a hint of it when grepping through the application,
and verified it in the manual.

Nice! This is something I've been researching within the last few days. I
have a pile of 4000 series CMOS logic chips I need to test before
reinstalling in some ancient boards, but I'm at a loss as to the most
efficient and simplest way to test them. Does anyone have any suggestions?
I think most of the chips are 4011, 4027, 4028, 4042, 4049, etc.

I have a hand-held chip tester that I got a while ago (+10 years). We
paid back its cost on the first use at work: an IBM 5150 PC that was
used as a terminal for a Northwest Instruments analyzer began beefing
about some problem or another. We gave the chip tester to an intern
and told them to start testing RAMs. Found the offending 4164 and pulled
one from the parts bins above his head. Put a $20,000 anaylzer back
to work.
In the absence of a chip tester, I have no good solution except to
build one. Given the level of effort involved, unless you are doing
it for fun, it's cheaper to go out and buy one.

found plans for a computer interfaced design by Silvio Klaic at
[http://student.math.hr/~sklaic/electronics/ictester/] (which currently
seems to be down), but I'm not 100% certain it would work for all the CMOS
logic chips I need to test. The software part of the tester looks like it
can handle the chips, but I haven't had much time to study the schematic
of the hardware. Perhaps it's time I buy a new breadboard (or repair the
old one) and wire up the circuit ;)
