[rescue] Finding older memory chips

[Bill Bradford]

I've got this circa-1989 Amiga memory board:

Anybody know if its still possible to find more of those RAM 
chips?  

The ones on the board are TI-manufacture, with the following markings:

TMS4C1024-12N
HDP 92277

Google turns up a bunch of "Contact us to have us find this chip!" 
results.

I'd love to be able to find 48 more chips, to max out that memory
expansion board.
