A few VT-320 and keyboard questions

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. Adam
