Here we have a PCB (005-003568) that apart from interfacing to the Data General Nova bus does nothing else. Of course that’s by design as this board is employed when you need to interface to something bespoke. This particular example was used in a system developed by ADT Security Systems to drive relays.
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 […]
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 by ‘nextstepglobal’ and I placed an offer on it which was turned down. After the initial auction had ended I was contacted via this […]
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 […]
This Data General 6341-A Tape Transport has arrived from the USA along with an interconnecting cable to a MV DC series machine. This particular example is is prety good cosmetic condition save for a few rusty bolts. You can follow its restoration HERE.
This Data General Eclipse S/140 Chassis has arrived, it will enable me to test my S/140 and Nova 4 CPUs and related PCB’s in due course. This particular example is the shielded version and formed part of a GE CAT scanner many years ago.
Data General Field Engineering Breakout Box Another blast from the past – anyone remember FE days fault finding ASYNC connectivity?
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 […]
