Giving away the boards I suspect I will always be too lazy to sell separately but that I feel are still too valuable to take to the recycler. The majority of these are mechanical, but don't expect to find any particular jewels among them as I would keep any I would consider such myself or (hopefully) sell them separately in future.
The entire lot is available for collection / pickup at my house only, take all or nothing. Please PM if you're interested and can be bothered to drive to Kassel for these. You can just grab the boxes and leave, but a coffee and chat are free, too.

Spoiler:
As a bonus, you have the option of picking up the box of Cherry offal (bottommost pic): none of these still have keycaps, some G81s are still intact otherwise. The G80s in there have had their sliders and springs removed. Some cases are still pretty decent (two 1000s, I think, the others are 3000s).
So here goes:
Three classic rubber domes
4x vintage MX blue (from top: Chicony 5192, Nan Tan (?), Chicony 5182, Auva)
Chicony 5182 and 5160 (both Futaba MA), Epson with inverse cross-mount tactile SMK, Tipro MX black
Two (I think) Chicony 5192, both with Futaba MA, Chicony 5182 with white ALPS, missing keycaps included but one or two stabilizers broken off, Cherry ML G84-something
Fujitsu-made Epson board with the plastic hammer thingy type switch (discussed at one point in Identify thread), Compaq Extended RD, broken RAFI Siemens-style switch, G80-18XX MX black
Tipro Futuro MX black, two interesting Sejin Futaba MA boards with the numpad on the left - the grids for handicapped people come off, Proworld or somesuch clone
compact G80 MX black, 3x rubber dome
two Acer switch boards (really great switches), very nice ALPS-mount caps, too, if not for the excessive yellowing, Cherry G83 with Cyrillic sublegends, Mitsumi RD
RD Model M by Lexmark
Magnavox Videowriter RD
Interesting laptop numpad with MX blues and Cherry M8 or somesuch for the compact keys, but doesn't produce any recognizable output via its PS/2 plug
