I was given a bunch of DG gear around Y2K. Kept a couple of Aviion boards to hang on the office wall after having to purge the system collection before moving.
As much as I love old gear, my interests are currently more modern. Still I'd like to put an OS on a smaller system, either ARM or MIPS. ST has a nice new Discovery kit that as a 2.4" QVGA TFT LCD and would serve has a radio controller prototype.
Aren't those cool? (the STM discovery boards) I got one of the original butterfly boards ($15 from Digikey) and then one of the DISCO boards (the one with the LCD) at ARM TechCon. I then started a Google+ "community" (Cortex M Developers) and started using (and trying to improve in small ways) libopencm3 (see it on Github http://github.com/libopencm3/libopencm3). Lots of folks are using these boards, they are pretty awesome.
