ToolShed Firmware & ROMs

ToolShed includes source code and build systems for several CoCo and Dragon firmware projects, including original system ROMs and custom DOS implementations.

Core System ROMs (cocoroms)

The cocoroms directory contains the assembly source for original Tandy Color Computer and Dragon ROMs. - Components: Color BASIC (bas.asm), Extended Color BASIC (extbas.asm), CoCo 3 ROM (coco3.asm), Disk BASIC (disk.asm), and Dragon equivalents. - Usage: These are typically used as a base for custom ROMs or for use in emulators.

Custom DOS & Extensions

HDB-DOS (hdbdos)

A powerful extension to Disk BASIC that supports hard drive images and SD card interfaces. - Baud Rates: Available in different flavors (e.g., _cc1 and _cc2) with different baud rate settings. - Formats: Builds as .rom (for controller replacement), .bin (DECB binaries), and .wav (cassette loading). - Note: This build depends on equates generated by cocoroms.

DriveWire DOS (dwdos)

Specialized DOS for booting NitrOS-9 or other software over a DriveWire connection instead of a physical floppy. - Function: Works similarly to the RSDOS DOS command but loads via serial/DriveWire. - Formats: Builds as .rom (motherboard or controller replacement), .bin (DECB binary), and .trk (boot track format).

SuperDOS (superdos)

A disassembled and enhanced version of the original DragonDOS, ported to various hardware. - Ports: Supports Dragon 32, Dragon 64, Dragon Alpha, and Tano Dragon/RS-DOS. - Build Targets: Use make all, make alpha, make ddos, etc. - Note: Still uses the mamou assembler by default.

Build Recommendations

It is highly recommended to have LWTOOLS installed for most of these projects. While mamou is included in ToolShed, lwasm is the preferred assembler for modern development.
