Hi all. I've got a 1981 revision of the Morrow Designs DJ-DMA fdc. It used the hard-sector North Star format for its 5.25 inch disks. I suspect the chips board got fried at some point when I had power supply issues, so I'm in the process of replacing them. If any of the PROMs were trashed, I may be in trouble. If anyone has any ideas on how to replace those, I'd be interested.
Also, on P. 1 of the manual, it states:
Thanks

Does anyone know whether they actually produced those, and does anyone know where they might be obtained?In the spring of 1982, IBM and Radio Shack 5 1/4 inch soft-sectored media will also be supported. Existing controllers in the field can be upgraded by replacing two of the ICs on the unit. This is done at moderate cost to the user
Thanks
