Needed - Static RAM board & more for Altair / S-100 project

Howdy folks, I'm just about in the final stretch of my Altair 8800 restoration (more like a total re-construction..) and there are a couple of parts that I obviously need to pick-up. FYI, this is a 'to factory' restoration, so the 8800 is going back to where it was when it was built from a kit. This isn't totally true, as this particular unit was later fitted with the "B" power supply and that will remain. It's obviously far superior to the "A" version and I don't have any of the A PSU parts. First off, I need a static RAM board for it. Ideally, I'd like a 1K or 4K MITS part.. but any +small capacity+ static board will probably fit the bill, particularly if it's has hand-drawn traces and is built on the clear-whitish board material as is the Processor board. I'm not sure what to call this color or type of board.. so please chime-in. Secondly, I'm thinking really hard about replacing the motherboard (or as MITS called it the 'expansion board'). As it sits, it has a Processor Tech. MB-1 16 (!!) slot board that's going to look a little silly with only two or maybe three cards plugged in it. Does anyone have an original 2 or 4-slot mainboard, or even a 3rd party board that's not so dang huge? So to this end, I have a few items to trade if that would work. There's a 64K (max 256K) dynamic RAM board, a Z-80 board, a floppy disk controller board, what looks like an RS-232 board, and a couple other minor items. All parts are in great shape, look ready to run. TIA for any and all help. Feel free to contact me off-list to work out deals. -Bill
