Ok, thanks

I think I might just get a new gotek for now and put this one to one side to look at in the future

Many thanks

Rc filtering?

Thanks

I've extracted the rotary controller from the GoTek and I can't for the life of me find anything similar on eBay/Amazon

Also, all the rotary controllers I can find, even if they say they are for gotek, only have 4 cables and this one has 6??? (2 black cables don't show up well in the picture ...

I've decided a white floppy drive looks a bit ridiculous, so will source a black one next week (along with a thumbnail sized USB stick like I use with my other GoTeks)

For now I've set the 2 buttons to eject/select, bit messy but it gives me a workaround until I look at this next week

Well, that's just because the rotary encoders (that's the thing that sits behind the knob) generally are pieces of mechanical crap and a constant annoyance. If the cabling between the encoder and the Gotek CPU board is fine, replace the encoder.

Your Gotek should have two separate pins for the ...

I have a number of GoTek, all of which work fine other than one

Originally I was going to use it with my BBC B or QL but discovered an issue where 'pressing' the rotary knob is very hit or miss on whether it works or not to select a folder/file so I put it to one side

This, because I'd forgotten ...

That sounds like that plate is flexing something and causing a short! look carefully for anything sticking out of the gotek, drives, etc!


I think I've sussed the cause, now all put back together and still working!

When I inadvertently ripped off the regulator attached to the bottom of the ...

I thought I’d have one last look at this for now

I reseated the socketed ICs & with everything else disconnected it works again

So I screwed the plate with the floppy drives back on (without connecting them) and it stopped working

I removed the back right screw and it works again, re-screw and ...

Extracted the ROM and it passed a verify check, so not that

I've since read that it's a known problem for the rectifiers to fail when upgraded to 2 disk drives (wish I'd noticed that before!) so will try replacing those (not a nice job by all accounts) when they arrive

Possibly explains why I've ...
