Default Re: Gemini 80-Bus System

I have added a -maxtrack option to he gm833 command line. You need yet another version of xbeaver.
Looks like your software likes a 2MByte ramdisk. Still needs the disk images gem925.dsk for hard disk and possibly the floppy image as well..

configuration file is as follows

cpuclock 4

#miss out these two lines to inhibit tracing
board 0x0 intbus 0x0 0xff xrwt trace
bus trace

board 0xfe gm813_mmu

board 0xb0 gm832 Gemini green
board 0xb8 serial_8250 trace tty tty /dev/ttyS0

board 0xe0 gm849_scsi ~/beaver/disks/gem925.dsk
board 0xfb gm833 -maxtrack 0x3f
board 0xe0 gm849_floppy -geometry D35.2.10.0.512 ~/beaver/gm512/GM512_ORIGINAL.DMP

#miss out this as well to inhibit tracing.
bus io

binload cb00 ./beaver/network/cpm64w.bin

byte 0 c3 00 eb

This does at least boot the system with M drive (ram drive).
