Have a working Intel Above Board Plus 8 with 2MB RAM and would like to
populate it to the full 8MB. It will take 120ns or faster 1mbit chips
-- but where can one find that kind of thing nowadays? Are those still
commercially available or am I going to have to scavenge them from
somewhere else?
Manual lists acceptable part numbers like:
Fujitsu MB81C1000P-xx
Hitachi HM511000P-xxS
Mitsubishi M5M41000AP-xx
Motorola M5M511000P-xx
NEC UPD421000C-xx
NMB AAA1M100-xx
OKI M511000RS-xx
Samsung KM41C1000P-xx
TI TMS4C1024-xx
Toshiba TC511000P-xx
...etc but google searches haven't been very fruitful (that is, the
pages returned when I search for IC part numbers don't return vendors
with plain pricing/availability info).
I just want a few tubes of these to populate the board, I'm not looking
for a box of 'em :-) Any pointers?

I want to use these to populate an Above Board from 2MB to 8MB, and that

Does anyone know of a cheaper way to get DRAM? $100 just so I can add
6MB of RAM to a card doesn't seem right...

Call MC Howard in Austin, ask to talk to Mel. If you want to, tell
him I recommended him. He has all kinds of memory lying around. Worst
case, you might have to peel it off a salvaged board.

ObUsualPlug: It's a fun place to lose a couple of hours if you find
yourself in Austin. For an idea of what you can find there, their ebay
store is mchowardelectronics

Well, you asked. I posted a "WANT" on the local Freecycle list for
any old 286/386 systems and got a couple of replies. One of them was
an old Micronics 386/20 system with 8MB of DIPs on the memory boards.
Cost me only the time to go across town and get it. Got a nice AT-
style clone case to go with it as well as bunch of other stuff.
If I'dve asked for CRT monitors, my inbox would probably be full.
The funny thing is that a friend recently had his house burgled where
the thief took his 17" no-name VGA monitor (left his computer) and a
rusty Buck knife. His insurance company valued them at $689, so cut
a check over his $500 deductible. I wondered how the malefactor was
going to fence a monitor that the local recycler charges $10 to take.
Cheers,
Chuck

There days you are better off gutting some cards/boards you do not like or
need to get chips then buying them online.
A while back I snagged a IIgs that had a transwarp in it for $10 (yes, even
I get lucky) and it had a RAM card that can do 6mb onboard (populated with
1MB of DIP). I looked around and found the cheapest a 1MB set of chips can
be had was $18 plus shipping, so to fully populate it I would need 5 sets
for $90 + shipping. Now I am too cheap to pay $90 so I looked around a while
and somebody had a dead Sirius 8MB card (that used 30 pin SIMMs x 8).
Snagged it with some other stuff he was selling (ram card was free) and
found it just had corrosion on some pins, cleaned it and it worked. I
considered that hitting the lottery twice in one week since the RAM card
goes for $175 new or $200+ on ebay (which is funny since you can buy them
new online cheaper).
For my Amiga 2091 SCSI card I ended up gutting the RAM out of a couple VLB
video cards to get 2MB onboard (came with 0 and with no RAM you have no DMA
and that is very slow).
Speaking of VLB cards I found that PCI Mac vram SIMMs tends to be the same
spec the higher end VLB video cards used and can be found dirt cheap. Just
pop them off the SIMM and stick them in your cards RAM upgrade sockets.
