Er, its an program that runs on the Palm Pilot range of handheld devices to emulate a Sinclair ZX81.
Currently, the program needs PalmOS V3.0 or above. It was written using the free GNU toolset.
If you need reminding what exactly a ZX81 was, look here.
|13 Nov 2001||First Public Release.
The emulator works but is very s-l-o-w. Keyboard entry is not finished. Load/save not yet supported.
|11 Dec 2001||Updated web site to be Netscape friendly!
Added support within emulator for both the "improved" and "unimproved" ROMs, but still no update for keyboard entry or load/save :-(
Added some more documentation.
This software is still under development! Expect Bugs!
