The Linux Kernel has support for DEC VSXXX mouse (as
well as LK keyboards), the opposite of what you are interested in.
So the conversion from DEC protocol is well documented.
It would be fairly straightforward with a microcontroller to implement the reverse.
See: https://code.woboq.org/linux/linux/drivers/input/mouse/vsxxxaa.c.html
Adding another reply: I wouldn't recommend to use the driver source
code as a starting point, but rather fetch DEC's specs about the two
mice (VSXXX-AA and VSXXX-GA) and their tablet (VSXXX-AB), which are
all described in the "VCB02 Video Subsystem Technical Manual",
available here:
