This is a test of [PC8080](/modules/pc8080/), a new 8080-based machine emulator being added to the
PCjs Project. It's a work-in-progress, so there's not much to look at yet. And the goal is not to build
yet-another Space Invaders/Arcade Machine emulator -- that's been done many times over -- but to start with
a well-understood 8080-based machine architecture that doesn't need a lot of peripherals, and use it as the

8080 Test Machine

This is a test of [PC8080](/modules/pc8080/), a new 8080-based machine emulator being added to the
PCjs Project.
This test machine loads a copy of the
[8080 Exerciser](https://web.archive.org/web/20151006085348/http://www.idb.me.uk/sunhillow/8080.html)
(specifically, [8080EX1](/devices/pc8080/rom/test/8080EX1.MAC)) and intercepts *just* enough of the exerciser's
CP/M calls to display its progress.
The good news: PC8080 passes all the 8080 Exerciser tests. At 2Mhz, the tests do take quite a while,
but you can click the speed button while the machine is running to increase the simulated speed; it will
wrap around to 2Mhz if you try to exceed the maximum speed that your system supports.
NOTE: The original [8080 Exerciser website](http://www.idb.me.uk/sunhillow/8080.html) is currently unavailable,
so we refer you to the copy on
[archive.org](https://web.archive.org/web/20151006085348/http://www.idb.me.uk/sunhillow/8080.html).
The 8080 Exerciser has also been "forked" on [GitHub](https://github.com/begoon/8080ex1).
