There was 4 empty sockets, however I filled them.

I could be wrong on the memory thing.  I might allready have
768k.  There was 4 empty sockets there and I grabbed some chips
off of an 8088 board that I had, and the timings were the same so
I plopped them in the Tandy.  The memory messages on startup
showed the extra mem (I can't remember how much though).

Even if I could put more mem in the thing, I don't really need to
since all I use it for is running Telix, and for 3 small programs
(programsize < 40k with no malloc()'s) that read/write to 8255's
connected to the outside world.  I don't multitask it or need to.
I might find more of a use for it in the future but right now it
does what it needs to.  It would be cool though if I could fit
all the stuff I need into a ROM chip!!!!!!!  THIS WOULD
ROCK!!!!!!!!!!

What does the acronym "TPA" stand for?
