Hi Chris,
The REX doesn't actually extend the RAM beyond 32K. Bert was meaning
that you can backup your 32K RAM to REX and restore a different one,
giving you multiple 32K RAM working spaces with different content.
There were a couple of RAM expansions available in the past, such as
EXT4 (from the 80's / 90's) or ReMem (Steve Adolph circa 2015 or so),
but to my knowledge, none of those are in production

Hmm, I don’t see that feature in the specs for REX#. It has 1mb of
Flash memory for storing ROM images and can backup and restore the
ram, but I don’t see and RAM on REX that would allow me to max out
Tandy’s onboard RAM.

Hi Chris,
Not the screen so much, but your REX will already give you oodles
of RAM
in banks of 32K. So you can swap out and in, as many RAM banks as
your
REX has space for.
I just discovered that recently while playing with my (original) REX,
M-100 and T-102.
Cheers, Bert
