Not sure if you saw, my post on fixing my floppy issue with board #1. It was a faulty YM2149 chip. When I replaced it, the floppy was recognised and worked fine.
Good news. :D Board number 1 has a faulty YM2149 chip which was what was stopping the floppy drive being seen. We did some diagnosing yesterday and found that chip was faulty by swapping them between my boards. We also checked board 1 to make sure that there was nothing bad with the soldering and co...
Small update, Board #1 is now alive again after re-soldering the NO BLITTER jumpers and removing the Bliiter chip. So it is back to booting TOS but not seeing the floppy. I have also tried re-soldering the WD1772 but this did not help. I tried removing the NO BLITTER jumper solder a 2nd time and got...
Board 1 continues to be a problem child. It now has a blitter fitted but it now shows a long row of bombs on a white screen.

This may be another source but not PCB mount: Thanks, it could be possible to bodge them in with a adapter pcb or something I guess... Yep, that was my thinking. Would need some right-angle pins and maybe a 3D printed plastic block to have the pins go through with a couple of square nuts on either ...
Small update from me. Now have sound connected to my video adapter cable and works fine. 3M PLCC68 sockets arrived from Mouser this week. Now waiting on blitter chips ordered from Best Electronics as they were the only supplier with stock. Also ordered some Atari Crytal oscillators from Best Electro...
