Re: DEC bus transceivers

Hi all, On my road trip earlier this year one of the docs I snagged was a ring binder of Foxboro Integrated Circuits dated 10/73, Revision A, one of 200 copies. It covers chip characteristics and compatibility cross references. This was part of the doc set for the Foxboro FOX 2/10 (PDP-11/15)

Re: Sage II

IIRC, TEC FB-504 is 80 track double density. IIRC, the Teac 80track double density is the FD55F (55G is 1.2M, 55FG is intended to be strappable as either) On Sat, 29 Oct 2016, emanuel stiebler wrote: TEC, sorry ! Ok, so both seems to be 80 track ... Those should be imagable (is that the right

IMD can't determine the interleave. I am using a DD drive, not HD. According to this page http://www.thebattles.net/sage/ they're 96TPI - I don't have a system set up for this at the moment. I have the kermit disk for the Sage II though. My B drive has an 8" drive that thinks it's a 720K drive
