Great video Tim .. very informative 😉

[@joelawford5107]

That was really vfm Tim. I am kinda dizzy right now but in a good way 😅

[@sergeypotapov1896]

Nice video. But I don't quite understand, how do you correct the disk spinning in the opposite direction? Thanks.

[@TimsRetroCorner]

I think the spinning backwards is something it does when it can't read the disc - in dase the disc is encoded backwards, I guess. Once it can read the disc properly it doesn't spin backwards. At least that's my experience.

Thanks for the video! I am currently trying to calibrate my CD32 too. I did not quite get the point when you adjusted pot 3 and 4. What do I need to look for on the oscilloscope? A signal shape that is as balanced as possible, without undulations?

[@TimsRetroCorner]

Yes, you're looking for the least amount of turbulence in the signal.

I’m just puzzled as to why you thought the 2 x Capacitors were installed backwards in the first place so decided to install them the wrong way round?

[@TimsRetroCorner]

Because it's a well documented fault, and brain was not engaged that some boards might be correct.

@@TimsRetroCorner Oh ok & fair enough, I’ve only just come back into the Amiga scene after owning an A1200 many years ago and finding an A600 that I’d left in my Brothers loft in the late 90’s albeit in a poor state of repair & missing the PSU & Floppy, I’ve replaced one of the Caps near NE555 as it turned on initially after buying a PSU and after a few minutes I got a BSOD and removing the Cap near NE555 brought the “Insert Disk Screen” back so I’ve since replaced that Cap, I’m not looking forward to replacing some of the other Caps though, I’ve also managed to mod a Samsung PC Floppy Drive to work with the A600 so it now loads Workbench 3.0 fine, Question for you, Should a standard PC Serial mouse work with an A600 or not as I don’t have an Amiga Mouse?
