Tim,
I'm afraid I screwed up. I finally found some other numbers on the
board. I don't know why I missed them before. I think this number is the
right one. It says "L2007" and "50-18290-02 A1". I counted the memory ICs
on the board. There's 144 of them and they look like 1 Meg chips!
The board is roughly 10 1/2 x 8 1/2" in size and has stamped metal pull
tabs with no markings. I scanned one board and posted a picture of it at
"

looks like.
