I have looked at the 'RF Series Integrated Storage Element User Guide' and was able to find a geometry for most of the DSSI disks. RF36 and RF74 though mentioned different number of sectors per track for different 'bands', which makes some sense given that outer tracks would be longer. Since I'm making virtual disks for open-simh, I'm probably just looking for a total number of sectors (especially for the RF74). Could someone point me in the right direction? Thanks, -Andy Ball.
I can't find detailed technical specs for either the RF36 or the RF74 but the 1993-MAY-10 Customer Update does include articles for both the RF36 and the RF74:
https://decuserve.org/anon/htnotes/dir?f1=INDUSTRY_NEWS&f2=611.*It's a bit light on nitty gritty technical details but it does give (rough) capacities so you could work backwards and come up with a number of sectors. A few other drives are listed so you could do the same for those and see if you get close to published sector numbers for other drives?
