The pinouts: http://www.camaronet.de/download/vax-pinout.html
The specs:   keyboard specs (LK201) somewhere in the hardware reference section
of the NetBSD pages

PC components don't match the requirements, keyboard and mouse use a
bidirectional async serial interface at 4800 baud or so. The protocol is
DEC-specific. But the only tip to get at least a keyboard: They are nearly all
the same on the VAXstations. LK201 is the standard, also used on VTxxx terminal
series, you can also connect a LK401, it has some more keys.

so long.. Michael
