Hello
Yea IBM has the BIG-3390 and the FAT-3390 and other names for the large drives.

But yes any number of cylinders up to the max of 32,760 would be fine assuming a MOD27. Call it what you want.

I said that I would consider making one 30049 cylinders since that equates to 3 3390-9 plus cylinder 0 for a volume label. (3x10016 + 1) A supposed 'standard' 3390-27 is 32760 cyls -- but past 3390-9 -- it's really arbitrary and can be 'whatever you like'...

A 3390-3 at 3339 cylinders, one for CP and an almost full pack mini disk is 3338 cylinders. So 3390-27 is 30051 cylinders. If you give the guest a pseudo full pack, that's minus one for CP, so 30050 Rob
