I'm something of a retro-computing buff. That's a nice way of saying that I'm a terminal pack-rat and completely incapable of throwing away equipment that still works (no matter how slowly, by today's standards).
You've got to love those old TurboChannel® boxes. Former Sequoia 2000 folks might remember the DEC 5900 file servers, “heel” and “toe”; I've got their brains (they come on convenient, easily-removed daughtercards) and Prestoserve® boards installed in a couple of 5000/240 workstation chassis. ULTRIX® just keeps going and going and going - I hope I can avoid going to NetBSD/pmax or DECstation Linux for a bit longer (the peripheral support isn't quite there, yet - wish I had the time and expertise to help).
The Sun 3 and Sun 4 machines are gone, as threatened.
