[sdiy] Emu Sp1200 format/write issues

[grant musictechnologiesgroup.com]

As much as I dislike Facebook, there is a Vintage Synth Repair group (that might not be the exact name) that is *very* active. Of course with Facebook there is no decent search-able archive, so you'd have to ask the question from scratch. Also there are a ton of SP1200 fan sites (if you haven't tried them already).

Subject [sdiy] Emu Sp1200 format/write issues


Hi all,
I have an Sp1200 that will not format or write to floppy. I’ve confirmed the drive is working on a different Sp1200. It reads fine. Tried a Gotek and still won’t write so it has to be something in the sp1200.
I confirmed the 7407 buffer feeding most of the floppy lines is good. Confirmed the Z80 sio that handles the floppy is good.
Now I’m getting lost as to where else to look. Anybody seen anything similar to this? Most advice I’ve seen is that it’s a bad floppy drive but I’m pretty sure that isn’t the issue here.
Thanks in advance!
Al
