I have about 20 lightly-used-in-original-box WinTerm VX0 V90's from Wyse from a project that ended up getting abandoned.
I believe it's possible to boot them from a Linux Live CD, as well as install Linux on them.
I want to get rid of them, not concerned about getting money for them, just don't want to pay to dispose of them. They are probably perfect as a dedicated hardware wallet, key generator, password safe, or anything else that would depend on a light Linux installation.
For 2 BTC I will ship one of these anywhere in the US. Many of them also come with a full-size keyboard and mouse.
For another 2 BTC, I have "wall kiosk" mounts for them (these are new in box). The "wall kiosk" holds the thin client to the wall, and then you can mount a 15" or so monitor on top of it using standard VESA mounts, so the thin client sits between the monitor and the wall. I only have maybe 8-10 of the mounts, but they look like they may be generic enough to hold things other than this particular thin client.
If you want one, place a dummy order for physical coins at

Just choose the "no shipping charge" option, and then pay 2 BTC. The 2 BTC *is* the cost, fully shipped to US addresses.
No warranty, since you're mainly paying for shipping, but I have little reason to think these won't work (not only are they nearly new, some of them will be practically brand new, taken out of the box only to load some other application on them).
