The normal mouse specs are in VCB02 Video Subsystem
Technical Manual,
EK-104AA-TM-001 (appendix C).
The LK201 is in there too.
It's possibly in the VCB01 docs;. Decades ago in New Zealand I had a Vaxstation II/RC
with QVSS.
The kernel, user-mapped producer/consumer ringbuffer code with hardware-to-X-event is the
same for both.
On NetBSD, probably microvax 3x00 and DECstation/turbochannelAlpha, too. I know I'used
both two-roller and one-ball "puck" mice on a mix while in grad school.
I think I have one of those mice with the non-round
connector, but I
also have a MIPS DECstation that I now suspect needs it :-)
The Personal Decstation (5000 /20, /25, /33, and /50) need an "access.bus"
mouse, 8-pin but with latches on the side. flatter than RJ-45. VSXXX-BB? All other
DECstations use the same round mini-DIN as QVSS/QDSS, via the 15-pin to MMJ/mini-DIN
cable.
Oddly enough I saw a PS2 keyboard-and-mouse to LK201/VSXXX adapter for sale on eBay, but
it's US $350 or thereabouts.
