I just got two old packard bell keyboards, 5130 and 5131C, PS/2, both rubber domes.
What's interesting, the keycaps fit very nice to a cherry switch.
Can post some photos.

This is a very cheap source of cherry keycaps.

I'd love to see some pics.

Nice, thank you.. looks like that's a bit of a luxury RD.

That's a [wiki]BTC[/wiki] keyboard. Sliders over rubber domes weren't unusual, and there are both Alps and Cherry MX mount sliders in addition to many proprietary designs such as NMB and Alps.

I've got an older Packard Bell keyboard, also BTC with Cherry MX mount keycaps, but only pad printed, so they're not worth anything.

My keyboard goes back to 1994, so I don't know whether the domes were any better in the 90s. I tested the keyboard recently, and found that the domes are (now, at least) extremely tactile, like typing on an Acer or Xiang Min (XM) Alps clone board, which may be due to the rubber having hardened, as I have no recollection of it being anywhere near that awful in the past.

For some reason I was getting a lot of mis-ordered letters, and I couldn't tell whether this was due to a fault with the keyboard, or me struggling to cope with such a stiff board. I don't recall that degree of mis-ordered letters with an Acer, for example. I do know that it has no blocking; years ago, I didn't know what ghosting was, and I could never account for the behaviour in games where two people shared the same keyboard. (It's why Lotus III "stopped working": I must have re-bound the keys for one player to something that came into conflict with the keys used by the other player, and it completely messed up the game, and I had no idea that it was the keyboard doing it — the ghosting was probably causing one player to brake all the time, but since the game has no implementation of brake lights, it just seemed that the car didn't want to accelerate.)

On my BTC keyboard, the stabilisers were unfortunately different from Cherry MX. The Esc keycap is also 1.25u on all BTC keyboards I have seen.

The 1u keycaps are very nice for being lasered ABS. Same profile as SP but compatible with O-rings. Nice texture like SP.
I am going to use mine on my ErgoDox, with thumbkeys from WASD Keyboards.
The text font is the same (or very close to) Lucida Sans Bold (an option for WASD Keyboards), but the font for numbers and symbols is not.
