If you want to purchase your upgrade kit from Radio Shack, it's
their stock number 25-4082, probably around $75.

If you want to purchase your own chips, you'll need 4 64Kx4 100ns
DRAMS (they go in the 18-pin sockets) and 2 64Kx1 100ns DRAMS.
The 64Kx4 chips should cost you about $4 apiece (mailorder) and the
64Kx1 chips should be about $3.  You'll need to remove the jumper
at E8-E9 and place it on E10-E11.  That's all.
