HP 2100/21MX boards available (and needed)

I have some boards available, and some others I desperately need. Trades anyone??? Available (and thoroughly tested to work - multiples of each available): + TRUE IN/OUT Time Base Generator (TBG) 13037 Disc Interface (the PCA, not the rackmount box) Jumper BACI High Performance Memory for E/F (various sizes) High Performance Memory Controller Standard Performance Memory (M, various sizes) 1K WCS for M?/E/F (only one available) WCS for 2100 (only one available - untested, and may already be spoken for) Need: 3 GRD TRUE IN/OUT 1 Firmware Accessory Board (FAB) 1 Dual Channel Port Controller (DCPC) 1 8-bit duplex register Notes: 1) I'd prefer the WCS & 1K WCS to go to someone who actually plans to do some microcoding, not just sit on a shelf 2) I'd prefer to trade some of the available boards for the needed boards, but may be swayed with other gear :) Regards, Jay West
