Technical notes

All system ROMs (monitor, BASIC, disk drive controller) are compiled into the binary as C arrays in src/rom/*.inc. Derived from Daniel Coulom's DCTO8D/DCTO9P/DCMO5 emulators. The .info declares no firmware (firmware_count absent), consistent with the code.

No BIOS or firmware files required. Generated on 2026-03-25T14:56:43Z
