First a little tidbit:  TI's 32K expansion memory is split into
two sections; one is 8K and goes in the low memory space and the
remaining 24K goes into what's left of the remaining 64k space.
Note that the 16K that's in the base machine belongs to the VDP
chips (9918a or just 9918 for the old 99/4).

As to 32K homebrew expansions:  I've seen a coupla but that's been
many many moons ago.   Try checking the ol' "99'er" Magazine,
currently called "Home Computing(?)".   Check the ads in this one.

Also, Triton, Inc., based in San Francisco (I think) sells expansion
hardware from a number of suppliers.  This was the company that took
over the TI software and remaining hardware when TI got out of the
home confuser :-) business.

Good luck,
