Milestone 2, phase A: one microdrive (mdv1_), read-only, loaded from a .MDV image via the Shell's Options menu. DIR mdv1_ and LRUN mdv1_xxx both tested working on real MEGA65 R6 hardware, including sustained reads of full-size programs.

See INSTRUCTIONS.md (attached below) for exactly where each file goes on the SD card, and CHANGELOG.md in the repository for the full milestone-by-milestone history.

Included

  • QL4M65-CoreQL-M2021_r6.cor - the compiled core
  • main.rom - Minerva 1.98, plain (no QL-SD driver - this core doesn't implement QL-SD yet)
  • back.rom - Toolkit II (TK2)
  • blank.mdv - a blank, correctly-formatted microdrive test image
  • INSTRUCTIONS.md - installation instructions

Minerva and TK2 are GPL/GNU-licensed and redistributed here on that basis. For other QL ROMs, see https://sinclairql.net/djw/qlrom/index.html.

Known limitations of this milestone: microdrive read-only (write support in progress), 128 KB RAM (no expansion yet), QL-native CPU speed only, PAL video only.
