An excellent question, but it is exactly the same

this morning just in case I'd missed something, and it's 72. The service
manual even warns against installing RAM there.
Is this actually a *non*-standard thing? I know Apple had all kinds of boffo
L2 cache configurations for the beige Power Macs but Apple's Apple and
certainly larger than Alpha Micro.
I'd expect SRAM rather than DRAM on a cache SIMM. Cache memory is
supposed to be fast after all. Otherwise why bother? -- caching only
complicates things, so there has to be benefit in return.
