1. IBM Pingmaster (JP layout) - £175
Brand new, open box - sealed until April 2025 and only typed on once briefly since.
Absolutely immaculate and unmodified, comes w/ all packaging and accessories. Only flaw is it wasn't double boxed on the way to me so has a postage label on the outside IBM box.
This was supposed to be a 'never sell' - you'll struggle to find a nicer one than this

2. Fujitsu F9746KK14 - £40
Good condition overall but quite yellowed. I don't know much about it. Peerless switches, caps are Japanese layout and made of some sort of ABS. Can’t remember how they’re printed but it feels alright to type on. Wacky connector, think it may be something to do with PC-98? More recent than you'd think, made in 1999.
3. Marconi Marine Spector 3 Keyboard-Processor - £35
Rafi RS76M switches, doubleshot keycaps in Danish layout.
I think this is more than just keyboard inside but I haven’t opened it up yet to find out. It was used on ships for radio communications stuff. It’s a bit tatty, but not too bad. One keycap missing + weird gouge in the lip of the spacebar as if someone’s put a cigarette out on it.
4. Cherry G80-1000HAY - £120
Decent condition, just dirty - will be cleaned before sale. Someone has scrawled Russian sublegends on it which I think will come off. Switches are MX Blacks, pretty mediocre. Case is mildly yellowed. Very nice doubleshot caps in a rare and obscure Yugoslav layout, I think Cherry came up with it themselves but it never really caught on.
5. IBM keycaps - £45
IBM call these: "DEC emulation and IBM 3708 attachment keycaps & keycap removal tool kit for IBM 3151 ASCII Display Station Keyboards". They look fairly similar to OpCon caps found on 122s.
I bought these as NOS so they should be in good nick. They're currently en route, just arrived in the UK and should be with me this week.
