* DOS wedge (direct mode only) - `@<drive_number>`, `@<command>`, `@$`, `@$<params>`, `@`
* BASIC extensions, see the [documentation](doc/Extended-BASIC.md)
* turbo tape load support (as device 7, or using `←L`), quite sophisticated: up to 250 blocks (can store bytes under I/O), automatically adjusts for tape speed differences
* turbo tape load support (as device 7, or using `←L`, optionallly with a file name), quite sophisticated: up to 250 blocks (can store bytes under I/O), automatically adjusts for tape speed differences
* normal tape load error log is limited by free stack space only (no artificial limitation like in original ROMs)
* tape format autodetection; normal vs turbo is mostly transparent to user
* improved support for tape adapters (for using regular casette players and other audio devices instead of Datasette) and emulators
