The 3-pin connector used as an alternative power connector on these
Connor drives is still available (I can't remember the brand/model
offhand, but they were also used for analog audio for certain sound

obtaining the correct connector shell and pins and use it to supply
power a 2.5" to 3.5" adapter board.
If I could trouble you for a link or a reference number or something, I
would appreciate it. I spent an entire night looking at Digikey for
such a connector, and it might very well be there, but I can't determine
the right keywords to find it. As noted, it looks similar to sound card
audio connectors used on some CD-ROMs, but I don't have any of those
cables to check, and the actual pins seem different.
I'll see if I can pull one out and cross reference it to something. These
were used for all sorts of products and I know they are still out there.
The difficult part would be finding the correct crimp tool for the
contacts, if you wanted to crimp them properly (soldering crimped
contacts, and especially those used for power is a no-no as far as I'm
concerned). The contacts are likely a JAE 2.5mm (0.1in) type contact.
You could also
use a CompactFlash card with a CF to IDE adapter board. They
even make some of these adapters in a 2.5" HDD formfactor which can be used
with a 2.5" to 3.5" mounting bracket.
Yeah, I have one of those around here as well (could not find it last
night. I figured my question would be valid no matter the specific
target HDD option.
A 512MB card would give you more than enough room to install MS-DOS 6.22,
Windows 3.1, MS Word 6.0 and Excel 4.0. All of these together would likely
install into less than 100MB.
How much
memory did you end up with in your 286/SLT? There are 3 slots
under that aluminum box/cover at the center-front of the machine with the
outer plastic shell removed. Those slots can use any combination of 1MB and
4MB modules, but those modules are proprietary and are practically
impossible to find today.
I have 2 1MB modules.
That's not bad at all, plus you have the on-board memory (640k IIRC).
Be very, very
careful with the LCD in these machines. The backlights are
not well supported and are very easily broken. I'm still on the hunt for a
replacement LCD for one of these that's been sitting in my project pile for
/years/.
I have not opened mine, but is it possible to replace just the backlight, or
is it a single encapsulated unit?
They soldered about a dozen flexible flat cables across the back, so in
order to open it up, you have to desolder all those cables first. Then,
the tubes they used were odd sized (IIRC, 2-pins on each end, with
heaters), and I was never able to match them up. With my display, while I
had it sitting out on the bench, someone else decided to "borrow" my iron
to repair something else and in the process dropped a hot solder bead
across the front of the LCD, destroying the tinted plastic that is stuck
to the face of the LCD (I had it sitting face up to keep dust out of the
back). Assuming I could find a replacement for that tinted self-stick
plastic and a pair of tubes, I could /probably/ still repair my LCD, but I
don't know where to obtain those.
