Floppies

[CTM]

Someone sent me two 16-sector, single sided, single density, hard-sector floppies. A friend said he thinks this may be what the Altair 8800 used. Might you know anyone that could read these? Thanks.

Depends on the controller that was in the Altair that wrote it. Hard sector sounds like a Northstar, or Northstar controller.

I think the Northstar used 10-sector diskettes...

Micropolis (e.g. Vector Graphic) used 16 sectors AFAIR.

I assume these are 5 1/4"?

Yes, that is correct. Northstar used (and for some, still use) 10 sector hard sector 5.25 inch disks.

If it was an 8800, it would have been hard-sector 8" and probably used the Pertec floppy drive (assuming it was all MITS gear).
