Got the ADDS mentor 2000 to boot today.
I have two small books which came with the system:
MENTOR Installation Giude M2000/M2500
Fortunately the installation guide has the pinouts for
the serial ports and some basic information about the
On power-up, on Port#0 I get:
ADDS Mentor Diagnostic Assurance Monitor Release 1.2
Copyright 1984 ...
(The following tests take about 15 MINITES to complete):
EPIC Test passed
RAM test Card 0000 Bank 0001-0003 (several times) Passed
PATSI Test passed
Disk Test Drive 0000 Track 0000-(approx 1300 hex) Passed
Tape Test - Tape drive not ready - Passed
9 Comm lines
Entering 'X' gets me:

Did you just reload OS from tape? (Entered NO)
ADDS Mentor (mumble) ... Login?
>From the Install Guide I determine that the username
SYSPROG is the "superuser", and the system does
recognize this name and prompts for a password (it
does not prompt for passwords to names it does not
know) - unfortunately I have no idea what the password
On the inside of the drive cover, I found a handwritten
label with two usernames and passwords - one of them
is either no longer valid, or I can't decypher it (hard to
read writing), however I was able to figure out what the
other one was, and successfully logged in to the system.
Unfortunately this username comes up with a little menu
system offering various business system options, and I
could not figure out how to get to a command shell.
(Entering BREAK locked up the system - 20 mins to
1) Does anyone know of a way to bypass the SYSPROG
2) Is there any way to make the system boot without waiting
for the power-on tests to complete. I can get to the monitor
command prompt, and I can run various tests from there,
but I have not found a way to boot the system other than to
power-off, power-on and wait for the tests to complete.
[One good thing I did find in the docs, was the command to
shutdown/park the drive properly from the monitor - useful
since I can't get to a command prompt - According to the
docs I need to be logged in as SYSPROG to SHUTDOWN]
3) Anyone know exactly what type of tapes this machines
uses (If I take it apart and get the drive model number, this
might give us a clue). I found a function in the monitor which
apparently backs up the hard drive to tape ...
4) Anyone know of a way to "break out" of a program launched
at login to a command shell (the docs says it's called TCL
for Terminal Command Language).
5) Anyone know what the "F" or "NX" commands do in response
to OPTIONS [X,F,NX]=
Do any of these options let me reinit the system, reset the SYSPROG
6) If I answer "Yes" to "Did you just reload from tape", what exactly will
this do? ... Will it let me re-init the system/reset the SYSPROG
6) Any other info, esp. about the "Diagnostic Assurance Monitor"
commands etc. Would be most useful... ?
PS: The TRS-80 Model II that I picked up along with it works
