Packages 586220, 785260, and related service ROMs as current single-ROM and switchable multi-ROM diagnostic cartridges.

Current choices on 2026-07-30 included Retro Rewind's in-stock CAD 22 C64 586220++ and C128 785260 cartridges, its CAD 40 four-ROM C64 cartridge with a two- to three-day lead time, AMI64's GBP 19 eight-ROM C64 cartridge with an approximately seven-day lead time, ogHugo's USD 26.99 before-tax two-sided C64 cartridge with an Add to Cart path, Retro-Updates' EUR 17.99 two-sided C64 cartridge, and C64iSTANBUL's orderable two-ROM PCB with current fabrication files. DIY8BIT's USD 22.95 781220/586220 cartridge was unavailable while its Etsy shop was on break. Retro Rewind's older Dual Diag route now displays the store's not-found page. ROM sets and model support differ by variant; a full port test requires a separately bought or built harness.

Tests a VIC-20's keyboard, IEC, user, cassette, and joystick interfaces with a machine-specific cartridge and loopback harness.

AMI64 listed its GBP 47 complete cartridge-and-harness kit as available in around ten days on 2026-07-30. CMD Marketplace listed three USD 59.90 PAL/NTSC kits, but its Tindie page exposed conflicting United States shipping text and no usable US rate. Sven Petersen publishes the GPLv3 hardware and firmware project.
