Tandy 1000 "Memory PLUS" expansion board w/"RS-232 PLUS" interface add-on

Tandy Memory PLUS expansion board (25-1011), with 512K, DMA controller, and RS-232 PLUS (25-1031) interface board.

This was one of the last items I "rescued" from a Seattle-based PC recycler before moving. It might be one of the best Tandy 1000 (original, A or HD) upgrades available, since it expands the memory to a full 640K, adds a DMA controller and serial port, and only occupies a single ISA slot.

I'm not sure what it's worth, so, if you're interested, please make an offer.
