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.
