Try M5M51008DFP70HIA0-ND from http://digikey.com $4.50 each, in stock.
I have some older Toshiba TC551001CF's that you may have if you don't mind desoldering them from a board...

I got mine from www.futurlec.com .
(I don't know if I got parts that conform exactly to your specs, but they work.)
At the time I purchased (several years ago!) Futurlec would take a no-minimum order. I'll leave it to interested parties to discover whether that's still true.
I do remember being pleased with their prompt service. (Again, this was several years ago.)
Good luck!

Hi H.D.
Let me know in a day or two if you still can't source the parts you need.

Oh, I forgot to mention that I need a 128kB chip (the one posted above is a 1MB chip) since I'm upgrading my 48G (starts with 32kB ram). I was hoping to upgrade to 384kB (128kB main ram, 128kB port 1, and 128kB port 2).
So far, futurlec.com has all the _other_ parts I need (74HC00, 74HC174, 104 and 143 SMD thin film resistors) but nothing resembling 128kB (8-bit) static ram chips.
Sadly, no distributor has a search feature that allows descriptive words as opposed to knowing part numbers. Mouser electronics is an exception, but they too do not carry the 128kB sized ram chips.
