On those long modules, are there 84 pins on each side of the stick? If so, they could be a 168-pin DIMM with FPM, EDO, or SDRAM. If there are contacts on one side only, it could be some kind of weird SIMM in a DIMM package.

Yep, you're right... I only looked at them briefly last night. Flipped one over and there's a "168" on the back side. Chips are SEC brand # KM416C1200AJ-6.

The "Apple 512K/2M" modules are part number 830-0316-01. These should be a 512KiB 80ns 30-pin SIMM made up of four 2 megabit chips. It's specified for the Mac IIci, IIvi, and IIvx. I believe they are also compatible with the II, IIx, IIcx, and IIsi.

Sounds like factory RAM that got upgraded at the first opportunity.
