Here are the specifications of his system:
Computer : D-116, clone of a DG Nova 1230 with 17 slots, also known as "Entrex 480" and "Nixdorf 620"
Core memory : 64 kW
Terminal : ENTREX DATA/SCOPE
Disk Cartridge : Diablo Model 40
Mag-tape : Pertec 8840A (800 bpi)
Line drum printer : Data Products model 2230
As the machine was distributed by Nixdorf, the identification of the tape and disk controllers is a bit difficult.
He is chronicling his progress on the ClassicCMP email list, and we are honored to feature the details of his system and restoration here:
It is a "Nixdor 600 series" (Apparently a Nixdorf 620/35), upgraded
several times until 1980, the CPU board is dated from this year. So I do
not know exactly what machine it is today the equivalent.
Anyway, the Nixdorf 620 is actually built by "Digital Computer Controls"
and after some researches it seems that it is a "DCC-116 E", the 17 slot
version of the "DCC-116" which Is a clone of the "Data General Nova 2/10".
8840A - A Disk Cartridge Diablo Model 40 and a big line drum printer
(Data Products model 2230), strange machine, there is a tape reader
inside the printer.

them and their position in the machine:

The scanner board almost never had a problem. Until you power the DCC,DGS system up you don't know.
