Hi all--
I've been playing with an old IBM PC340 a buddy salvaged me out of a hotel he worked for.
Works all right, but as usual I'm not satisfied with leaving it stock.

Right now it has:
A Pentium 133mhz (non-MMX, P54CS)
128MB of RAM (maxed I believe, more than enough for the DOS/95 I run on it)
A CF-IDE adapter
A 2(?)MB Stealth 64 Video VRAM PCI
Some random ISA Sound Blaster Vibra that will be replaced with something better once I have it.
A Gotek Emulator for the floppy drive
The original IDE CD-ROM drive.

My first question is regarding the cache:
This is a model with no cache sockets, but I'd love to solder some in and get the chips.

According to the product catalog on Lenovo's site linked in another PC340 thread, I can upgrade to 256 KB with eight 28 pin 3.3 v SRAM DIP modules and one 5 v TAG RAM DIP
Does anyone have a source to point me to to find chips compatible with this? I believe these are standardized parts that are not IBM specific but I can't seem to find any. I know the sockets themselves should be standard affairs.

Second, I had bought a non-Overdrive Pentium 166mhz MMX to put in, which is a P55CS. The product guide lists that an Overdrive is required. I am finding conflicting information on whether the board will work with a 166MMX non-Overdrive (given that some Socket 7 boards work without the adapter), and whether or not I would need a voltage adapter (which I cannot find on any site so far for sale). Getting a Socket 7 Overdrive would be a bit out of the question given their obscurity and cost.

Does anyone have any info they would be willing to share on these questions? I can post some pictures later when I get home.
