If the terminal you are talking about wants a PS-2 keyboard, as my VT501 does, you need a protocol translator.  It would essentially be the reverse of the LK201 emulator for PS-2 keyboards I released a while back, and possibly the same board could be used with a rather different program running on it.

Geeze, at that price, do I need to start clearing out my keyboard collection?  Nope, not going to do it...

I’m actually in pretty good shape, plenty of LK201’s & LK401’s (from my VT320’s, VT420’s, and workstations), plus a couple LK450-AA’s and a PCXAL or two.

I’m just not clear on if there is any difference between a LK412-AA and a LK450-AA, both have the WPS keycaps, both have the PS/2 style DIN connector.

I do wish I had a couple LK402-AA's (basically a 401 with WPS keycaps).

I also wish I knew why I have two LK450-AA’s. :-)  Though I’m glad I do.

Besides a terminal with ReGIS Graphics, the only other terminal that would tempt me is a Honeywell, but then I can connect to Multics from a VT420 just fine.
