[comp.sys.tandy] Mail Order Sources

Can anyone suggest a good mail order source for Tandy products?
Specifically, I am looking for additional memory for a Tandy 4000.

Thanks.

I just added some memory to our tandy 4000.  It had 2mb on motherboard
and I added 8mb on memory card.  I purchased the 8mb from a local store
NOT radio shack.  From what I have seen/heard/talk-to you can use standard
simm modules as long as they fit.  The only problem you will have is 
obtaining an expansion memory board.  You must buy the board from 
radio shack.  Everyone I talked to said that memory expansion boards
that are 32 bit interface have special interface (pin out) for each 
manufacture.  The other problem you may have, is that you only have 
a limited number of memory configurations.  You can have

	1mb      - 4-256k simms on mother board
	2mb      - 8-256k simms on mother board
	4mb      - 8-256k simms on mother board + 8-256k on exp board.
	8mb      - 8-1mb simms on mother board
	10mb     - 8-1mb simms on mother board + 8-256k on exp board.
	16mb     - 8-1mb simms on mother board + 8-1mb on exp board.

You might be able to find another manufacture that would allow less than full
population on the expansion board, but I looked for several weeks with no luck.
Having 10mb is quite nice.  Our sco xenix system (after 2 weeks up) has 0
pages swapped in/out.  A good indication that we have more memory than we need.
Hope this helps.  The store I purchased the memory from was Golden state comp.
at 209-638-6381, in case you can't find a distributer for memory.
