Hi Leo, Hang onto the floppies for now. If you can find them, we'll walk through trying to archive them. DJ, I spent yesterday trying to make the 1600 boot from a Gotek and I could not make it work. However, if you have the correct 3.5" floppy drive, you can boot CP/M from floppy like above. Th...

Forget about what I said in the last comment. I got the Nabu 1600 booting CP/M 86. I tried to get it to work on a Gotek and a 5.25" floppy drive but no luck there, yet. The floppy is a quad-density floppy disk that is not high density, but not double density so this presents a bit of a problem....

I replaced the component but that did not fix my communication issues. What I was seeing was a initial boot okay but as I rebooted, it would get less and less through the initial POST until, for whatever reason, I had to turn everything off, wait a while and then try again. As it turns out, I was mi...

Well, I got a little further but not too far. After spending lots of time on it and the 1600 hanging when I started to communicate with it, I found a bad 74ALS645 at U42. I have just ordered a replacement. I made the proper DTE to DCE pigtail adapter and that didn't help, obviously, but that was bef...

I got my Nabu 1600 today. First issue was a bad power supply. It would work for a few seconds and then shut down. +12v and -1v were fine but 5 volts was never achieves. There is a small round transformer that had a chip out of it so I'm not sure if that failed at some point and is causing the issue....

Hi DJ, I was fortunate enough to find a Nabu 1600 so I'll also see what it can do. The one I am getting (hasn't arrived yet) does not have an MMU board like yours does. It also does not have the internal memory expansion board so mine is just a stock 1600 from what I can see. in the meantime, I'm lo...

DJ, if you have good pictures of the Nabu 1600 motherboard, we can see if there is a floppy disk controller chip set on the board. It's also possible that Leo's MSU has a "floppy out" port that connects to the 1600 but I would otherwise think that the floppy disk controller is onboard.

It was still a good session but it might be best to just ask the same questions so the recorded version is like the session. You could not hear the audience ask questions anyway as Jeff repeated them for the stream.
