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 buy 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 […]
As well as the Pharaoh (Data General One) VIP John (USA) also very kindly gifted me a complete set of Data General Microfiche covering up to the early MV’s along with their peripherals. This is an incredibly useful source of technical information and will be very well looked after. Because of this I have invested […]
DHL delivered a very nice surprise to me today courtesy of VIP John (USA). John has very kindly entrusted me with his Data General Pharaoh (DG Model One 2-T) from his days with Data General Field Engineering. I have given it the name Pepi II. This example is in pristine cosmetic condition and has clearly […]
Both my MV/9800 and MV/9600 CPU’s have a Field Engineering (FE) SCP command which allow access to the Error Log for the PCB. So if a PCB fails a self-test (as my MV/9800 does) the only way to obtain detailed information about the error is to access the log. In addition the FE area also […]
