Subject: Help needed with VT-180 I/O Configuration

I am recently possessed of a DEC VT-180 system which runs CP/M
(among other things.)  Unfortunately, while the system is new,
I recieved absolutely no useful technical information for it.
For obvious reasons, I would like to get to the various I/O devices
on my own without trusting the the DEC-written BIOS.  Does anyone
have precise information on the location and protocol of the I/O
ports on this critter?  Disassembling the BIOS is beginning to
bum me out!

                       Thanks in advance,
