That's not a PC standard drive -- 5.25" came in >180K, 360K and 1200K varieties, whereas 3.5" came in 720K, 1440K and >2880K varieties (not including superfloppies.) > > -hpa It sure is a std drive, Peter, although many of the later ones that were set up as 1.2 megger's by the pc crowd who have access to a 500 kilobaud controller, could have the 360 rpm spindle jumper'd back to 300 rpm, and when fed with a 250 kilobaud controller (WD177x/277x/279x family, which includes the Fujitsu MB8877), they are perfect 720k devices and are spec'ed that way by the makers. Many of the older full height Tandon 100-4's could also step quite a few tracks closer to the spindle & I ran them as 765k drives by using 84 tracks. I even have a chinon that will make 86 tracks most of the time. These were all quite common in the middle '80's. Before your time I suspect. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
