Default Re: Gemini 80-Bus System

In relation to floppies, I have just realised that one of the main differences of BIOS 3.4 MFB over 1.4 and 3.5 is that CP/M starts at track 0, side 1, sect 1 for 3.4 and track 0, side 0, sector 1 for 1.4 and 3.5. I have a feeling that this has already been highlighted in the thread but I hadn't picked up on it.

I only noticed/realised when I was trying to fix the cpmtools 'gemqdds' definition which is wrecking my disk images.
