Thanks Chuck. The Gazelle uses the Tarbell DD controller which uses a 1793 which I believe is 3742 and s/34 compatible.

I had a look and a mental fart. I have the 842--the full-height model. I suspect that the jumpers are completely different. If you can use IMD to format both FM and MFM at 500Kbps on your 242--and "Analyze" reads the format okay, your SCP disks aren't probably standard IBM 3740 or System/3 type diskettes. They could be in a proprietary recording format, such as Intel MMFM or Futuredata GCR. --Chuck
