Xitan CP/M 2.26 - 48k - for Northstar - Model ????

[ldkraemer]

I've stumbled across the following README.TXT in the Dave Dunfield NSCOS File:

XITANCPM.NSI

NorthStar Disks in CP/M Format

N2212_64 Q NorthStar CP/M 2.2 release 1.20 - 64k

XITANCPM D Xitan CP/M 2.26 - 48k

S = Single Density (Single-Sided SD - 90k)
D = Double Density (Single-Sided DD - 180k)
Q = Quad Density (Double-Sided DD - 360k)
* = Image was made from original master diskette.

I would like to locate a bootable Image or a Floppy Image that has the first
0x400 bytes from a bootable XITAN CP/M Floppy.

The version in Dunfield's Image has a corrupt directory:

This image isn't bootable since the first 0x400 bytes are mostly 0xE5.
The Directory can likely be easily fixed.

Thanks.
