I have a wyse wy-50 and a vt101 in good condition that I need to get
rid of... I'm wondering if they're even worth putting on ebay.

yes, esp if the vt101 has a working power supply.
I don't know what is is about late 70's DEC switchers, but
just about everything I have now with them in is dead (VT100's,
11/44's, et al)
Those power supplies are not that difficult to fix (they're actually more
pleasant to work on than more modern SMPSUs in my experiece, since most
of the control circuitry is on the isolated side of the supply). I've
done both of them...
However, the VT101 PSU is totally different to that in the VT100. The
VT101 supply has a big mains-frequency transformer. I think the regulators
may well be switchers (at least for the 5V output), but I would have to
dig out one to check. It's not a real SMPSU, though.
