Ready-to-use Binaries

If you have built a P112 from a bare board, this is what you need to get it up & running:

To burn a system ROM, use either of the ROM files 1996 version or 1997 version (included in ROM.ZIP). The later one has a few extra bugfixes, but the earlier is more widely used. Your choice. You will need access to a ROM programmer for this.

To make a boot disk, download DSKIMAGE.ZIP, containing the disk image and a copy of rawrite. "rawrite" is taken from the Red Hat Linux 6.2 distribution. Format a 1.44MB floppy with MS-DOS, use rawrite to copy the disk image to it, and you're ready to go.
