All The Good Ones Were Taken

Z1a - Online Emulator

Usage Notes

A Z1a BASIC quick reference is available.

Click on the emulated screen to disable your browser's keyboard navigation for this page, and click elsewhere to restore it.

The ` key emulates the Z1a's EDIT key.


If you've disabled JavaScript, this won't work.

If your web browser is a relic, this may not work.

If you're using a keyboard layout I haven't encountered, some of the keys may not work.

The BASIC interpreter almost certainly has a lot of bugs in it.


This emulator uses Molly Howell's Z80.js, with some bodges of my own for partial Z180 support. Until I get round to setting up a public repo, Z180.js is here and MIT licensed for the taking!
