OS-9 Boot diskette for GIMIX I

OS-9 GMX for GIMIX

TThis GMX boot disk was recovered from an Internet archive. The distribution is notable for the fact that some utilities are designed for an 80-column terminal. This applies to Dir, Mdir, Login etc.

ROMs

The only OS-9 software that has been saved for GIMIX is a boot floppy disk and two ROMs for a Level I system version 1.1. GIMIX is however a profile on Microware's source code disk and it was possible for me to assemble a new kernel for version 1.2. The profile assumes a RAM limit at address $E000, a 58167 real time clock device at $E231 and will initialize a DAT register located from $FFF0 to $FFFF.
