I just picked up a VT-320, with no keyboard.
I have some questions:
1) the price on DEC keyboards, at least on eBay, is insane. Does anyone have a VT-320
keyboard they?d be willing to let go cheaply?
2) ?or, failing that, I found a posting of someone who?d done an Arduino-based key code
mapper that let him use a PS/2 (or maybe it was an AT) keyboard as a replacement. The
link to the actual project was dead, though. Anyone have schematic and source code for
such a project?
3) If anyone's got a DB-9-or-25-to-MMP cable you?d sell cheap, I?d be happy to buy it
instead or making my own. OK, that?s not really a question. There?s a blank insert where
the 25-pin connector usually is; was that a ?feature? of the B2 model? (that?s a question
but not much of one)
?aaaaand while I?m here, another question.
4) I have a number of Apple IIs and one III that have sustained some keyboard damage.
Where can I get/what is the name of the little plus-shaped keyboard stems for those? If I
had a couple dozen that would be most helpful.

The VT320 can use an LK401 or an LK201. I have a defective LK201 you can have for
shipping, if you want to repair it.
The M0110 keyboards usually used Alps SKCC tall cream switches.

I have one complete one

missing a couple of caps that I will sell for half that.

Isn't it just a lk401? I bought one recently for $55.

Unless you are doing this in bulk, I suspect it would be more expensive...
there have been lk201 hack a day stuff, though. Iirc, all the software is
available, but when I went looking, the board layout stuff wasn't.

MMJ is a pita. But getting a normal RJ45 and removing the clip will let you
plug it in and get it working.

You can use a LK201 or the seemingly less desirable LK401 with the VT320.
There are a number of LK201s on eBay right now for reasonable prices. The
cheap ones are always going to be untested/dirty/possibly missing a key or
two.
The thing to do for MMJ converters is to get a MMJ cable and an adapter.
The 9-pin I use is a H8571-J, I don't have many of those so I can't provide
one. The 25-pin I use is H8575-A, I have a few of those so if you wanted to
buy a MMJ cable and a MMJ -> DB25F, I could sell you that combination for a
reasonable price. I have a huge spool of DEC OfficeConnect branded
Spectra-Strip flat cable, a ton of MMJ crimps, and the necessary crimp die
to make up cables of whatever length you'd like. Contact me off-list if
you're interested.
Thanks,
Jonathan

I ended up springing for one that was a bit more than $50 shipped. The lot of 9 for $150
is very tempting, especially if I could talk them out of some of the shipping since I am
also in Tucson and wouldn?t mind picking ?em up, but that?s way more keyboards than I am
ever going to have DEC terminals, I think.

the cables are known to bad fairly often. Get a known good cable to test
them..

I don't know. Don't those also work with VaxStions? You could easily use three
like that, plus some spares...
