Ruined my A1200 installing an Indivision Mk3

[matt64]

After installing my Indivision Mk3 my Amiga is now missing green on the display output and my floppy drive won't boot / read disks. In workbench inserting a floppy just shows DF0: Unreadable. I never got any output on my indivision either. I'm guessing I killed Lisa and the CIA U7 somehow.

I was as careful as I could possibly be taking everything apart and putting the indivision in. All I can guess is that maybe one of the sockets must not have been seated quit right and shorted some pins.

Is there anything I can check or any advise you may have before I try to track down a replacement lisa or CIA and just replace the chips?


Any help would be greatly appreciated.

Figured out that the video problem was the small SMD resistor next to Lisa, the pressure of snapping the indivision in place had cracked it. I still don't know what's wrong with the floppy drive. I did some swapping and my A500 drive works fine in my A1200 so luckily it seems that no chips were damaged on the board.

That being said what would cause the motor to just quit spinning? I disassembled the drive but didn't see anything obvious, jumpers were set ok.

Did you chek the power connector pins on the drive?
Over the Time I had some that broke free of their solder pads.
May be the timing was just right for this to happen.
And the other thing i have problems with form time to time, are
the micro switches for the disk recognition.
They tend to get flaky,

Checked continuity of the switches, that checked out ok. Cleaned them with deoxit and reflowed them for good measure but no change. Reflowed the power connector as well. Also changed the 10uF caps on the drive and reflowed the flat flex cable between the boards with no luck.

The heads move and the drive tries to read, but the motor doesn't even try to spin even with a push.

Perfect time to fit a Gotek?

I busted my A1200 a few months ago refitting an indivision mk2. I have the same black screen problem, i must check that resistor you mentioned.

I thought about that, but I like the physicality of floppy disks, changing them, hearing them make noise. Plus it keeps the appearance as authentic as possible.

I don't feel so bad knowing that I'm not the only one. Those sockets snap on so tight.

Buy a D520, no need to open the Amiga anymore:

Unfortunately reading online its a common problem for any devices which require a direct mount.
Personally i feel awful busting my original A1200 so will be avoiding these solutions in the future.

I bought an OSSC as ive retro consoles also. The d520 is a nice bit of kit but jez thats insanely expensive for what it does.
