A disk operating system for commodore 64/128.

This project attempts to make a disk volume of useful system software for a c64/c128 system, to complement ROM based software normally used on these systems. It is meant to be somewhat analogous to 'system disk' found on other systems. It makes a commodore work say more like CP/M while retaining compatibility with most legacy software.

It currently includes:

• A boot loader to set colors and autoboot programs in appropriate mode (c64 or c128)
• An interactive setup utility to configure the bootloader
• A suite of tools including shell/monitor program kmon and file utility pip. These are separate for c64 and c128 mode, so you can take advantage of c128 features like faster disks.
• driver/editor to use c128 VDC chip in c64 mode, providing 80 columns support
• a set of useful third party programs, such as drivers, languages, editors, etc. These come mostly from commodore sources.

Makefile builds 1541, 1571 and 1581 disk images. 1581 + Jiffydos is recommended.

Rebuild with:

$ make clean disks

Start with:

$ x128 run64.d81

Or write the image to disk to run on actual hardware.
