Technical notes

System ROMs embedded in binary: chargen 600 (901237-01), chargen 700 (901232-01), kernal (901244-04a), BASIC 128K (901242+3-04a), BASIC 256K (901240+1-03), plus all drive ROMs (1001, 2031, 2040, 3040, 4040, 9000) and CRTC palettes (amber, green, white). Embedded ROM check in sysfile_load takes priority over filesystem. Models: 610 PAL/NTSC, 620 PAL/NTSC, 620+ PAL/NTSC, 710 NTSC, 720 NTSC, 720+ NTSC. 600 series uses CRTC with 8 scanlines/char, 700 series uses 14 scanlines/char (different chargen ROM). CBM-II uses IEEE-488 bus (not IEC serial), so no JiffyDOS support. Cartridge slots (Cart1-Cart6) are user content, not system files.

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