From: utzoo!decvax!ucbvax!eagle!karn Newsgroups: fa.info-cpm Title: Article-I.D.: ucbvax.7646 Posted: Sun Jun 13 20:41:56 1982 Received: Mon Jun 14 01:12:33 1982 Is it possible to write a formatter to run on the WD 1771 floppy disk controller that will produce disks readable by the WD 1793? If so, has someone written one that I could obtain? It is my understanding that the 1793 is pickier than the 1771 about what it finds in the inter-record gaps, and that the gap contents are under control of the formatter program. I have a Tarbell single-density disk controller, while my dad has obtained a CCS 2422, he can't read any disks formatted on my controller. Thanks, Phil Karn BTL Murray Hill, NJ
