Good to see, there is some of this awesome hardware still existing. It will be a long way to go to get it running. Probably there was no in-depth documentation available to anoyone not working for DataGeneral. If anyone out there wants to get an idea, how hardware engineering and the ‚war‘ among IBM, DEC pp. went these days, read ‚The Soul of A New Machine‘ by Tracy Kidder. It‘s about the successor of the NOVA, the ‚Eagle‘, but you get much info on NOVA, too.

Thank you for this! Actually, there's quite a bit of documentation available for the Nova at novasareforever.org/dgdocs.hw/index.php And yes, I've read that book you mention several times...it's a great read!

I was a technician that worked for Data General and Digital Computer Controls on these minis and others. My specialty was the CPUs but worked on other boards also.

dennis pengelly, thank you for sharing this! The DCC copies of DG machines is actually the key reason that I became interested in the Data General machines of this vintage. I've begun to collect all of the DCC-branded documentation that I could find on the DG Nova... entrex480.blogspot.com/2019/05/digital-computer-controls-d-116-16-bit.html Of course, I know that it is all copied nearly identically from Data General, but the fact that it was done, and became a real profitable company before running into enforceable opposition from Data General fascinates me! Can you share experiences with this? Thank you so much!

Happy years with DG UK, USA, Europe and Middle East. Seems most in SFO had no training on Nova Super Nova or 1200 (1979-80) so happy days. Incidentally some may know this but the nova was designed around Intels and Plessy (uk) 4 bit micro slice processor. Conceived over a meal In a Boston Italian restaurant, circuit drawn on the tablecloth ! Use to hang on the wall in Southboro office. Worth a fortune now........

Several Data General publications on Bitsavers. At least a paragraph on the 4010 option. Very enjoyable video!

@Cliff Miller thank you very much, yes! I did intend to mention in my video my previous searches on bitsavers.org/pdf/dg/ not producing a power-supply specific manual, BUT of course deeper searches will reveal more. I'm building a page on my power supply build at bit.ly/2k2OWX4 But, could you please elaborate more about what you mean when you say "a paragraph on the 4010 option"? I'm not quite clear on what you mean. And thanks again for watching and commenting!

26:15 could the 4010 option listed on the tag here stand for the 4010 I/O controller for paper tape and teletype. If that’s the case wouldn’t all novas have that option stamped on it since wouldn’t all have been ordered with that card to allow for easy interface

Maybe the mystery latches are there to latch the cabinet into the equipment rack? P.S.: I have a Nova 3. It doesn't have latches like those.

@@ForgottenMachines My Nova 3 is in a rack, but it's just held in place by friction and dirt. Its cartridge hard drive (model 6045, if I recall correctly?) has a solenoid-operated latch which only allows it to be slid out when it's powered but unloaded.

@@ForgottenMachines You are correct in assuming that the leavers are for locking the chassis into the rack, they can sometimes be a real pain to get to engage correctly, I have just been up to have look at exactly how they work and it has taken me about 15 mins to get them to go back into place and tighten up in the right location. My system is a Nova 820 all racked up with a Diablo drive disk system with 4 model 30 drives (3 removable and 1 fixed), I also have the paper tape reader and punch units but these are not connected at the moment as there is not enough room in the rack. But more importantly when I got how of the system I also got all the manuals and schematics that were with it so if you need any specific info I may be able to dig it out.

@@johnhenryrose Thank you SO MUCH for this comment, and the wonderful feedback...AND I really appreciate your offer to help with schematics. I think I'm going to take you up on that very soon. But I'll record another video and publish that on KZitem so the request is easy to quantify. And thank you again!
