I worked for Digital Microsystems from 1980 until 1984. The company was located in Oakland California at 1840 Embarcadero Cove. We produced many innovative products suchs as the SPX (Serial Port Expander) and the DMS-5000. The DMS5000 monitor used a mercury switch to determine the actual position of the screen for either full page letter format or widescreen speadsheet format. Our head Engineer Joe ??? was a Berkeley grad and loved his watch that had a built in calculator (c 1982).

I worked for DMS from 1983 through 1985 in NY as their Eastern Region Support Manager. (we sold to Columbia University Teachers College to name a few). We were in charge of the distributers on the eastern half of the US.

I was put into business by DMS and was given 1/3 of all inventory remaining after the sale. It was shipped cross country from Oakland to my new warehouse. The unit you were speaking of was the DMS816 which was a PC Dos version on the HiNet lan.

I still have some equipment of theirs if anyone wants to fork over thier life savings : ).

I also still have many repair parts including DRAM and power supplies which I will part with.

I worked for Daro Office Systems (Australian distributor for DMS), and remember working with the US engineers to rewrite the record OS locking routines. There were several companies using a one of the first PC multi-user accounting systems called Darofacs, and it needed special routines. The record locking code had to fit in such a confined memory area that we had to manually code in Z80 assembler and had to manually optimize code to use 2 byte relative instructions where possible such as jump relative (jr) instead of the normal 3 byte absolute (such as jmp) just to save a 300 or 400 bytes. DMS also released an early PCDOS workstation workstation (not the DMS5000) but I cannot remember the model.

Complete "soft" keyboard (its own 8048 processor)- any key could be programmed to command string, function or character.
The DMS 5000 was also available with an 8087 math co-processor. It was a CAD workstation and ran an early (beta) version of AutoCAD. I still remember...
