Of course, 4900 feedbacks is alot too. From the
picture, the simms look
like 70ns parity ram, but since the picture is off center, and he states
they are 80ns, the only way to know for sure would be to ask him. 70ns
parity modules could be used in many computers besides a Mac, but 60ns
would be much better for mid to late 486 and early pentium PC type boards.
I don't recall seeing board that claimed to support 16M 30 pin
simms. Do they 'automagically' support this size, or is it just a small
group that actually used 'em?

The explanation I've seen is that 4M was the biggest [commonly?]
available when the SE/30 was in production. But I've seen a lot of
references in NG archives to SE/30s running 128M. I'll tell you in a
week or 2 if 80M works.
FWIW, even a full set of 4M SIMMs (32M) requires the MacOS Mode32
extension on the SE/30. Its ROM is "not quite" 32-bit clean. LowEndMac
notes that there are claims that a IIsi ROM chip fixes the 32-bit clean
issue, but those are very rare.

I've got a few 486 and early pentium class boards laying around that can
support them. At the time those boards were new (1995 or so), memory was
around $25/mb, so 16mb of ram was $600.

Err, $400, but you get the idea :)
