Tests

Some my emulator tests:

• Minfo (source) – Measure frame and interrupt request time, contention. (2025)
• Colour Panels
• Timex modes
• Z80 type detection (source) – adaptation of Sergey Kiselev's CP/M test
• Keyboard & Kempston test
• zxtests-3.tar.gz (2011)

• Flash boundary effect test
• EAR test

Qaop popup

Script to show popup with a program running in Qaop/JS: qaop-popup.js. The HTML should contain proper link with data-qaop attribute:

<a data-qaop href=//torinak.com/qaop/#l=//example.com/program.tap> Title </a>

Cross origin access should be enabled for a tape or a snapshot to load. In .htaccess put header set Access-Control-Allow-Origin *. Also, file type is inferred from name suffix. To override this, set content type to application/x.zx.tap or the like.

Example: CC2011.

Misc
