I couldn't really find a home for this (not modding anything really, just discussing the board), hopefully this subforum will do.
I recently acquired a Dolch PAC 60 keyboard, but couldn't find very many resources on it (only PAC61-64/5 and other models like the 386).
From what I know, this board is unique in the series of Dolch keyboards because it has a built in PS/2 connector rather than the more common RJ45. I guess my first question is why only this model? Were the folks over at Dolch growing tired of making adapters for their computers?
Anyways, when I got the board in the mail, it was in rough shape to put it nicely.

Unlike most PAC boards, the PAC 60 has the PS/2 connector on the upper-left hand side of the keyboard

Again, this case...is rough.

Note: There is actually no screw under either the back or the front logo, I think I remember reading this was the case for most Dolch boards, but not this one.
I removed the logo and unscrewed the case and PCB from the board.


Some keycaps...you guessed it, it's time for a bath!


(please disregard my dirty bathtub >.<)
While things are in the bath let's look at the PCB...

There is some...sort of sticky substance on the back. I had another 1800 imported from taobao and noticed the same thing, maybe it's something with old cherry boards? Or both are just dirty

)

Cherry Vintage Blues. They feel great, nice and soft, somewhat lighter than modern MX Blues. The real winner is the spacebar...that MX Green is awesome.
....
After a while I went to check on the cases, and saw not much was happening. I guess the rubberized coating on the outside of the keyboard is standard. Either way, the rubber was so worn on each side, so I decided to strip the coating off of the case.

I am a fan of the brushed look. I was able to scrub the entire board and give it the matte look; both the top and bottom case are currently air drying and I will let them dry overnight.
More to come!
