- 1. The static ram chips are of a different package size than regular
- drams. Srams appear to be about half again as long as equiv. drams.
-
- 2. I've seen 32kX8bit sram chips for $14 apiece. So, for 8 chips (256K
- of cache) that comes to $112. Not really all that bad.

- I'd say it's time to start saving those aluminium pop cans.

- Mark.
