Re: [N8VEM-S100:1884] WTB: Northstar S-100 floppy disk controller

Are you sure?
As far as I have been able to find out, all their FDC's were all hard sectored. I think the reference to the 179x controller IC in the article you referenced is talking about competitors hardware. Maybe I'm wrong. I often am.

Not so, they made two very different FDC’s, the early ones were for hard sectored 5” disks, the later FDC was 179x driven for 8’ & 5” soft sectored disks.

Hi everyone,

This may be a long shot, but I'm in need of a Northstar S-100 floppy disk controller card. They made a few different models, but I think anything is fine for my needs.


Much thanks in advance
