While it certainly might be, I don't see how THIS makes it one.

The only daughter card that I DON'T remember being available would be one
for MORE memory.

Docs? , Drivers?
I'll be glad to, but it may be a while.
I have two totes full of them!, but they are on the bottom, back side of
the few hundred totes containing the residue of my office.
I know where ONE of the totes of them is, and can probably get to that one
soon. The other tote will happen when I get to it.

I did something real stupid when I moved out of my office. I tried to
organize the stuff that I was packing. For example, I put all of my
staplers (regular ones, binding ones, heavy duty ones, deep throat ones,
...) into one box. Now I can't find 'em, and have NO stapler.

OB_historical_pedantics: John Henderson? (Tall Tree Systems) approached
me (and others) at the West Coast Computer Faire, with a question of "have
you written any programs that use lots of memory?" We thought that he was
trying to recruit people with experience in memory management, etc. for a
project. He wasn't. He was coming out with MASSIVE memory boards, some
with MORE THAN A MEGABYTE! of memory for the PC. He wasn't looking for
project workers, he was looking for existing stuff that could comprise a
market and use for his product.
(That's what you have)

Eventually, he found the application for it. He marketed a laser printer
controller, that bypassed the 256K, text only, controller of the HP
LaserJet, etc, and created complete bitmap images in RAM (on his board) in
the PC, and dumped them straight into the printer engine.
(That was the JLASER board, with 2M of expanded RAM and laser printer

Later on, Lotus, Intel, and Microsoft met (and explicitly did NOT invite
Tall Tree, the primary provider of such boards!) and worked out the
"Lotus-Intel-Microsoft Expanded Memory Specification" ("LIM EMS"). It
took Tall Tree less than a month to make revisions to be compatible with
their "standard".

He also produced the very popular JFORMAT, which was a simple device
driver for squeezing 400K on a disk (10 512 byte sectors per track), as
well as doing 720K and 800k on 96TPI low density (Tandon TM100-4, etc.)

I have JLASER, JLASER-PLUS (with scanner interface), JRAM, JRAM2, JRAM3,
JDISK, ..., ..., It's not very organized, and I know where one tote of
them is, but not yet where the other one is. Who wants some?
