I found (via the classiccmp mailing list) an intriguing Data General item; intriguing because I have not seen a unit like this before. I made enquiries with the owner and they did not know what it was either. They also sent me a picture of the rear of the unit saying “you should be aware
Welcome to my Data General Corporation (DGC) Preservation and Restoration site. The aim of this site is to preserve and restore systems that were designed and built by Data General Corp and whilst doing so provide as much information on those systems, peripherals, software and documentation as possible. If you are considering scrapping or sending anything Data General (DG) related for disposal to a salvage or recycling please consider sending it for preservation instead. You can contact me here if you have any Data General Systems, Peripherals, Displays, Documents, Manuals, Cables, Terminals, Parts, Spares, Floppys or Tapes you wish to dispose of.
Data General Systems were used across the world – Not only were they sold directly to end users by Data General themselves but they were also embedded into many industrial, military and commercial systems by OEM’s. I cut my electronics teeth using Data General systems (read more in about section) and I have very fond memories of these systems which is why I recently decided to buy and restore my first system which happens to be an MV/9800 – one of the last 15″ form machines made by Data General.
The site is very much work in progress so check back often to see how the projects are progressing.
An important part of any restoration project is thoroughly checking the power supply unit (PSU) of the equipment you intend to restore. A fault with a PSU could potentially render the whole units electronics dead so its critical that you ensure that the PSU is operating as designed. Take notes/pictures before removing any cables or
Something that is new to me is the Data General Burst Multiplexor Channel (BMC) bus. When I used a Nova 3 and Eclipse S140 the BMC bus did not exist. As far as I can tell this was introduced with the advent of the MV/8000 (Eagle). The BMC bus allows PCB’s to transfer data direct
This Data General Enterprise MPT/100 has arrived for restoration and preservation – it’s a sweet little machine that has a microNOVA CPU hiding inside, dual 5.25″ floppy drives and integrated keyboard and display. It would have run MP/OS. More to follow on its dedicated restoration page here. I am looking for Documentation and Software for the

Data General (DG) History
Data General Corporation (DGC) was founded by several engineers from Digital Equipment Corporation who were frustrated with DEC’s management and left to form their own company. The chief founders were Edson de Castro, Henry Burkhardt III, and Richard Sogge of Digital Equipment (DEC), and Herbert Richman of Fairchild Semiconductor. The company was founded in Hudson, Massachusetts in 1968.
Edson de Castro was the chief engineer in charge of the PDP-8, DEC’s line of inexpensive computers that created the minicomputer market. It was designed specifically to be used in laboratory equipment settings; as the technology improved, it was reduced in size to fit into a 19-inch rack. Many PDP-8s still operated decades later. De Castro, convinced he could do one better, began work on his new 16-bit design.The result was released in 1969 as the Nova.

This site was created to help preserve the history of Data General Systems by acquiring (thru salvage, gifting, purchasing or trading) and restoring those systems. In doing so we can hopefully create an informative reference for each item that we acquire for future reference, from complete systems, peripherals, PCB’s, spares all the way down to the cables used to connect items together.
We are based in Oxfordshire, United Kingdom and are able to advise of the best course of action should you have a Data General System or associated equipment or software that requires disposal. We can also advise on and provide data destruction on those systems whilst retaining (where possible) the physical hardware for preservation. We can also (where required) physically remove disk storage for destruction or provide data destruction certificates. Please use the Contact page in the menu above or click HERE.
