Jeff, using the filter that Greg suggested helped me set my expectations
and range.
I picked up a NEC PC8201a for $114+shipping (CAD) before Christmas, and a
complete-but-partially-functioning (and I'll likely have questions for this
group about it) M100 in February for $45 + shipping (CAD). I hop
It's pretty much a case of "wait for the right auction." I passed on a
bunch of slab tops before I found the T102 that I have. I ended up getting
it for less than $100, and I'm very happy with what I got.

Because the 8k modules are already available from arcadeshopper. And, if
you are a hacker or cheapskate, the memory chips are not uncommon.

What are the going prices for m100s these days? I wanna make sure I bid
correctly on eBay. Thanks.
I have a few 32K memory modules I’m testing that another list member came up
with. One design is 32K of FRAM and plugs into the #3 socket and you run a few
wires to pick up the other needed signals. The other plugs into the System bus
socket. Both take over all 32K of RAM address space.

Seems like such a thing is long overdue.
The 3801 8k variant is very common.
I made up a board today to test. It has a single 128kB SRAM chip, and some
logic to decode the 12 (16) /CE signals into address lines.
In fact it is a 32k capable module, with the usual case being 24kB. the
