Colex system came in several variants, all identical on the outside :
----------------------------------------------------------------------
Colex 820 : basic 2-floppy CP/M system
Colex 850 : floppy/10MB MFM HD CP/M system
Colex 850 : floppy/10MB MFM HD CP/M system for a multi-user environment
Colex 3240 : UNIX ( CP/M-68K
Colex 3250 : MC68K based system with 10MB MFM HD and (UniSoft?) UNIX
----------------------------------------------------------------------
My system is a Colex 850 running CP/M 3
The system ROMS are saved in bits/ROMS and identified below.
The contents of the 10 MB MFM HD is saved in bits/Colex_10MB_hd_cpm3.bin
This is a straight binary dump of disk, as generated with David Gesswein's MFM-reader.
