There is almost no information available about this M2000 minicomputer.
ADDS (Applied Digital Data Systems) was a subsidiary of NCR Corp.
The ADDS Mentor 2000 is a serious multi-user business machine the size of a small refrigerator. This system runs the "PICK" operating system. If you ask knowlegable people what "PICK" is, some will say "Operating System" (OS), and the others will say "Database Management System" (DBMS). Both are correct, the PICK operating system is designed around a powerful database file structure.
The Mentor M2000 was one of the rare Z8000 based-system, and was able to manage 16 or 32 video terminals simultaneously.
About the pictured system, Neil Boulton, its current owner says:
Believe me, there is nothing mini about this computer!
Sometime when you turn it on after long periods
because of the fans and the tape drive you can feel
the floor shaking...
Thanks to Dave Dunfield for some info
Further information from Richard Jowitt:
EDP was the European Distributor & service maintainer for and of the ADDS Mentor products.
EDP shipped over 5,000 Mentor units. We have all the Mentor manuals in our library together with masses of Mentors and Mentor parts, going back to 1981/2.
When NCR sold ADDS, EDP brought to market its own C++ Object based UniVision Multi Value DBMS in 1994, ported to all flavours of Unix. 5.6 million lines of Pick assembler code re-implemented from scratch in just 120K lines of optimised C++. (Object delivers all that was promised!)
UniVision permits any Mentor user to take a FILE-SAVE of its Mentor system, perform an ADD- ACCOUNTS on a UniVision system, re-compile the application, logon and execute the application. That simple.
However, instead of running at a tiny 16x, as the first Mentor 3000's did, UniVision 9.0.1 runs at a massive 5,000x on a Dell 1900 with Linux ES 4.0, or if you run the 64 bit UniVision implementation, which we have not released, an even more massive 8,400x.
We need more info about this computer ! If you designed, used, or have more info about this system,
please send us pictures or anything you might find useful.
I worked at EDP in Sheffield and then Milton Keynes from about 1986 to 1989. I worked for Alan Lees who is mentioned in another post. I repaired all the various ADDS systems supplied and eventually supervised the repair center eventually...
I loved programming in PICK. Nothing else like it. Taught me about data structures and objects long before that was even a thing, it just made sense.

I was the Technical Director of the Spain reseller for ADDS Computers since 1985 to 1992. In summer of 1986 I meet with an Engineer from EDP U.K called Alan Lees at Lisboa (Portugal) for the M2500 training course.This M2500 system was an excellent computer, very noble and powerful. I can say that M2500 was the best system for Pick O.S. in 80´s decade at Spain. Around 1990 were substituted by NCR/AT$T Tower 200,400 y 600 series with the name Mentor 6000 series. Same hardware but different O.S. Unix for Tower an Pick for mentor. M2500 brings back good memories, unfortunately disappeared, however I keep an old M6000 that I´m sure that will startup. Regards.

ADDS Mentor was a joy to work with $ Pick OS was revised and was fast. The late, great Eugene Nathan Johnson was a fan. Prime took the fun away too soon thereafter, but the Mentor was always the sweet one. Standing next to the "fridge" with terminal on top was a happy working height. I remember this was a good looking box in black matte. I''d love to have one to play with again.
