It seemed like I/O was overlapping memory.  Maybe that was a
feature of EISA.  I figured it was an addressing problem, ala
Expanded-RAM, backed it off till it worked and called it good.
There's not much in a DOS/W31 system that will use anything
above the 16MB line anyway.  Since it runs DOS/W31 just as
good as always, even better when I got an Adaptec 1740, then
2740, SCSI and a "HUGE" 1GB Seagate ST51080N, and then a 3COM
3C579 NIC, I just left it alone doing the same things it has
done for the past 15 years.  That's long enough to run down
one of the Dallas Semiconductor 24-pin RTC/battery!
Fortunately I had salvaged another (Socket 5?) MoBo that had a
more recent one I could plug in.  I hate to see a good horse
put down, and this one has carried me many a mile in 15 years.
I use it every day.

It has a SCSI tray adapter and I have two 2GB ST32105N(IIRC)
that will run either NT/4WS or RHL6.1, but it's powered down
most of the time.

 PR> tested with more than 16MB.  Who had 4MB SIMMs in '91?
 MK> I've run across a few.  Hard to come by that is for sure.

In '91?!?!?!?!  I never saw one until way later, though maybe
a mfr like Micronics could afford some "engineering samples."
With 1MB SIMMs there's no way Micronics could have tested it
beyond 16MB.  I figured they shipped it with a "well, it ought
to work."  I just looked in the manual and it claims it should
work up to 64MB, but then there's a jumper for the segment
13MB-15MB cacheable or not, so maybe it's just something about
the EISA configuration.

 PR> Hafta see what I've got available.
 MK> Sounds interesting.

I've got a couple FIC PT-2200 HX chipset boards, one that had
a bad SIMM pin, and the serial ports don't work on the other.
I know I can desolder and swap the SIMM pin.  You learn a few
things when you assembled your first computer like a Heathkit!
(Hmmm, or is it a ISA socket finger?  No, I think that's one of
these SuperMicro boards.)

 PR> 1MB, and the 8 4MB that wouldn't run.
 MK> Hm.  I am not sure I'd give up on those.

You should see some others I've got.  A local company called
Memory-Time made some boards that you could solder 1MB 16-pin
DIP's on, and a buddy in LA sent me an old VAX memory board
just loaded with 'em.  Get out the blowtorch and knock 'em
out.  Got 8MB of those!

Gawd!  Ain't the history of computing wonderful?  I started on
a 2nd generation IBM in '66 (see website).  Then with my first
IMSAI in '76, I figure I had the same experience as 1st
generation computers, e.g. standalone block time, no OS, I/O
addresses assembled into the code, flipping front panel
switches to boot!  I'm getting all teary-eyed.  None of these
kids today give us a bit of credit for experience, but it's
them I feel sorry for.

 PR> Nope, twin boxes.  Same case, MoBo, cards, tray adapters for
 MK> I suppose.  Never was an issue here thank goodness.  :-)

Computing's part of my life.  I've got to have something that
works!  I learned how to do single point of failure analysis,
and to take steps to avoid 'em.
