- I do not have the direct answer. However, I have something which may be of
- help to you, or be useful for general info:
- In the appendix for Kenneth Heyda's "MULTI-SYSTEM 180 with ZCPR2.3"
- there is a list of system format parameters for about 20 manufacturers.
- I will copy it to here if desired.
-
- E.g., XEROX 820 SD has 18 sectors/track, 128 bytes/sector, and is
- (of course?) S (=single density).
- XEROX 820-II DD has 17, 256, and (of course?) D.
- There is no other Xerox listing.
