Green Alps Clone?

[terrpn]

Looks like a cloner to me?

Never heard of Yachi (last picture) before? Has KB 6251 in the second picture?

Not that big of a deal for a board, but it did clean up fairly well. Had to fill in missing keycaps with some odds and ends I had on the shelf........

It's a Nan Tan KB-6251 or KB-6252 (the model number on the case does not always match the PCB):

If you look on that page, there's a "6752" with green Alps clones. I think the "7" is a mistake personally. Most of us have V5, which has "2".

The switches are most likely to be linear. It would be interesting to see inside one of them to see what internals they use. I've never seen the numbering on the other one, but on yours I can.

What's the date on the controller chip? (In YYWW format hopefully.) Mine seems to be 9031, making it 1990, although mine has genuine Alps switches.

----- Will pop it apart tomorrow and grab the date and picture for you

I did not know this went through....... I kept getting errors and had given up on it (the thread)

[terrpn]

is this what you are talking about?

That's the one. 1993 week 5 then … Interesting. I need to get 002 to check the date on his SIIG MiniTouch, as that appeared to be made at the time that those style switches (with the simple numbers) were being replaced with the new numbering.

nice keyboard

It's not bad. It's got a plastic plate, so it's lightweight, but it's still better than modern office keyboards. If only NTC had made one with Windows keys and proper ISO enter and 2 u backspace.

If someone has one of these they want to unload (for cheap-ish), or even a handful of loose switches, hook me up!
