I have two 6100/60av's with no cache, so I just bought one for each. Came out to around 4 bucks total after shipping, which still isn't that bad for the performance increase.
PM 6100/60av: PPC601 60mhz, 72 MB RAM, 250MB HDD, Apple AV Card
Performa 600 (broken): 68030 32mhz, 20 MB RAM, 160MB HDD
Pismo: G3 500mhz, 640MB RAM, 30GB HDD

500 of them.
I wondered about buying that.
But then I realized.

What the heck would I do with 500 L2 DIMMs????????

Maybe you could configure most of them as a really fast 100MB RAM Disk Box, but it'd have to sit on top of your IIfx . . .
. . . unless you break the PDS Connector out to the BOTTOM of the MoBo so the fx can sit on top of the case! :lol:

Well, I thought that the SRAM cache chips might be useful for something, even though they're only 64KB (or is it 32KB?) capacity each.

So I went hunting for a datasheet, but these things pretty much pre-date PDF datasheets.

Some more hunting, and one of the kind folks on the Classic Computer email list sent me a Motorola Data Book for their Memory Products from that era. So now I have the datasheet for that SRAM, but it is some funky specialized stuff.

I can't imagine an application for it, where I wouldn't just be better off buying some larger, faster, more recent SRAM memory.

its so funny i bought a preforma 6xxx same as the PowerMac 6100, except it has 60mhz cpu and no cache, i had a extra cache stick .. i threw that in and i very much noticed a pretty big speed up! in pretty much everything.
