I'm going to sell a few keyboards to raise money for yet more keyboards. I want to list these, but I don't know what they're worth. I washed all of these in a bucket of simple green overnight, and spritzed the electronic ones with a bit of de-oxit just to be sure, so they're devoid of cracker crumbs and the plague.
1) A Unicomp 104-key buckling spring USB keyboard, in matte black with grey keycaps. It's in pristine condition, almost unused; I never got to use it much because I kept waking the family up at 2:00 in the morning. :/ No packaging with this one, just the keyboard.
2) A black Happy Hacking Keyboard Professional, with topre capacitative switches. Comes with all original packaging, documentation, and removable USB cable. I used it for about a year before switching back to larger keyboards, so it has some minor signs of use, but functions perfectly and has no noticeable defects.
3) An IBM Model M for terminals. Part No: 1392595, I.D. No: 5213912, Date: 02-07-92 (!), Plt No: F7; Model M. No original packaging, just a brown box. This thing has a connector that looks more like an old telephone line than any modern digital connector, and has a plethora of strange, antiquated keys that only make an inkling of sense to me through using emacs for too long. More of a historical oddity than a usable keyboard, though I suspect some brave, atavastic soul willing to sauter the connection and write his own drivers the way they did in ye olde CompSci could make it usable with a modern computer. Also good for salvage, if you'd rather have a "Reset" or "Send" key instead of an Alt, or if you'd like a "Jump" key to put where escape goes so you can pretend it deploys a parachute.
4) A Topre RealForce 104-key in very good condition. I've used this board for about a year, and it works as well today as it did when I bought it. The only sign of use is some shiny texture on the spacebar where my thumbs rest. All original packaging and documentation.
I may not list all of these, depending on the price estimate. I won't be listing them on GH, because I don't have enough forum posts to make a classified ad. More likely, they'll be on eBay. I won't link any sales I make since it's probably against the rules.
