It was not my intention to start the restoration of the 1200 so soon after it arriving, but I stumbled upon someone who could recreate the overlay for me so the 1200 has jumped the queue. I was also able to locate some original switches for the front panel so I also took the opportunity
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.
This Data General 6012 Terminal (Serial Number: 1961) was due to be my next acquisition to sit alongside my recently acquired Nova 1200. It was being offered for sale on eBay and I placed an offer on it which was turned down. After the initial auction had ended I was contacted via this site by
This Data General Nova 1200 has arrived from the California USA, its missing its CPU PCB and has some damage to the front panel (switches) as well as a very degraded overlay. The Nova 1200 was launched in 1970 which makes it 50 years old this year. The plan is to fully restore this machine
Data General DTOS 8.1 on cassette. Here is a blast from the past – anyone remember loading DTOS from cassette tape? This is way before my time but I suspect this was the next stage on from Paper Tape before 9 Track Mag Tape became prevalent. VIP John (USA) has very kindly entrusted me with
This Data General Corporation Integrated Circuit is used on an Intelligent Lan Controller (ILC) board which came with my Eclipse MV/9800 the PCB also has an Intel 82586 IEEE 802.3 co-processor. Does anyone recognise the 48pin DIP labeled A01 and have any information on it and/or the PCB? The PCB part number is 005-039526 –
With lock-down in place here in the UK restoration work has stalled as systems are either at my place of work or in storage both of which I am unable to attend. So in order to stem the withdraw symptoms I have been continuing work on an extender for the Nova/Eclipse bus. I am about
A recent day trip to France has returned (for restoration and preservation) and following items: Data General MV2000DC Mk 1 Data General MV2000DC Mk 2 Data General Desktop Model 20 Along with: Circa 150 DG Floppy Disks Circa 150 DG Tapes for MV2000 inc Microcode for MV1000, MV1400 and MV2000 Various DG20 Spares (PCB’s, Disks,
More AViiON related media arrived this morning including: AViiON SCM Update Media Rev 17.00 Prom 4.4.0 (CD)AViiON ix86 In-Service Diagnostics Rev 8.0 (CD)AViiON m88k In-Service Diagnostics Rev 8.0 (CD)AViiON System Diagnostics Rev 12.40 (CD)DG/UX Release 4.20MU05 Documentation (CD)DG/UX OS with X for Intel Release 4.20MU05 (CD)DG/UX Maintenance Update 5.4R3.00.MU05 (Tape)DG/UX OS with X for 88k
I have finally found the time to start work on the restoration of the MPT/100. I have removed the Main PCB and started the long process of component inspection, cleaning and component testing. The picture shows the area previously covered by the brightness potentiometer and its mounting hardware. This was the first component to be
Brian contacted me recently after stumbling across my site. His father (Roland Quillia) was with DG for over 20 years (70’s – 90’s) and mainly oversaw the Westboro and Southboro Facilities in Massachusetts but had responsibility across the US. Brian has fond memories of being inside the DG headquarters many times. He has also very kindly
Suprise delivery this week from the guy I acquired the AViiON 5500 from, he found a keyboard, some further documentation and two tapes one for DG/UX 5.4.2 and AViiON Diagnostics Rev 13 (12.60). You can take a look at the inside of this machine and follow its restoration by clicking here.
Having had another batch of Data General PCB’s delivered today I thought it best to start to take stock of what I have ‘in the shed’ just in case something is of interest to someone but more importantly to ensure I don’t acquire something I already have (my memory is not what it used to
Another new project has landed today – a Data General Desktop. Having had a quick look inside it appears to be a DG10/SP model with Winchester, Floppy and Tape. I believe it is capable of running CP/M, RDOS or AOS. You can take a look at the inside of this machine and follow its restoration
When I embarked on this hobby I made a pact with myself to stick to the ‘proprietary‘ Data General CPU’s e.g. the native Nova/Eclipse and MV machines, however recently I stumbled across an Motorola 88110 based AViiON server and intrigue got the better of me when the owner confirmed that it had a full set of
One thing that has genuinely surprised me is how much ex Data General people want to help with physical items for a restoration and with how much information they remember about kit they worked on many years ago! VIP Alexandre made contact with me completely out of the blue and offered to send me 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.
