cpm hdd

[paulmackay]

128 byte sector * 65536 ~= 8MB max for a cpm2.2 logical partition
16 bit maths limitation in bdos
You will also be constrained by the maximum directory entries.

use cpm 3 or rewrite bdos
8MB of cpm files is a hell of a lot of files. trying to navigate that many files with only 16 user sections to put them in is also going to be fun.
ymmv

I am not up to date on cpm. whatis the 16 X users and will cpm3 run cpm 2.2 (microbee software). also what would the difference be between 2.2 and 3.0 for harddisk use (size, maybe sub directories)
