I hate optical media...
Spent a frustrating afternoon trying to find at least one writer that would burn me an ISO. Eventually managed to do so reliably on a LiteOn 52x32x52x - at least. if I set speed to 8x.
Of course, the ISO in question turned out not to work either, so now I need a new one and have to start all over again. Joy.
In between that, I cleaned two filthy keyboards - a BTC 5339R-0 tactile foil&foam dinosaur and a similarly old Laser-branded Monterey/Keytech K104 alps white clicky beast. After disassembly, chucking keycaps & membranes into a pillow case that went into the washing machine, putting the plastic upper enclosure into the dishwasher and thoroughly manually cleaning the rest, then putting it all back together again, the boards are spotlessly clean although rather yellow (long live ABS keys...). That BTC was fiddly as hell.
End result is an Alps board that I might well use as my new default test bench keyboard - it's robust, types beautifully and has an XT/AT switch on the bottom. The BTC is... interesting... it's my only capacitive keyboard but 30-year old foam is downright crappy and makes the board type very irregularly. Probably something I'll keep as a curiosity, nothing more.
Apart from that mainly tidying up, de-duplicating bags of cables, removing three desktop systems someone should be buying from me this week from under the spare bed, then shoving boxes/tubs of stuff in the space freed up. Later this week I have another crateload of tested stuff to try to flog, and another one to test. Once I get those out of the way perhaps I can get down to some of my more long-term projects...
