Jupiter Ace Emulators for Windows
We are lucky as there have been a few emulators over the years. Some are more useful than others, the
odd one has features that none of the others have such as EightyOne with its WAV loader.
Some have been abandoned for different reasons by their authors so development has
stopped on some.

SpudACE runs very well with Windows XP/Vista/7 & Linux with WINE installed.
no$zx v2.0. The program has originally started as a two-weeks hack for emulating the ZX81, but now grew to a decent six-months project. Aside from improved ZX80/ZX81 emulation, it's now also supporting the Lambda and Jupiter ACE, alongsides with the complete ZX Spectrum series (though the older monochrome sinclair models are still looking more fascinating to me ..Martin Korth
Is an emulator written by Mike Wynne which will emulate a number of simple machines
including the ACE.
" It may or may not work on Windows 95/98/ME/NT4/2k/XP. I have no
means of testing it except that it runs on my Windows XP laptop. It comes with no warranty,
use it at your own risk. I think the "Simple ZX81 emulator" is a little outdated now -
EightyOne is the most accurate ZX81 emulator available for Windows (And probably any other
system too)" :- Mike Wynne.
EightyOne Version 1.00 runs fine with Windows 95/98/ME/NT4/2k/XP and now Vista compatible.

Vace version 1.0 was programmed for fun by Edward Patel. It has some loading and saving
capabilities, but no snapshot function or sound.

What is MESS?
MESS is an acronym that stands for Multiple Emulator Super System. MESS will more or less
faithfully reproduce computer and console systems on a PC. MESS can currently emulate over
250 systems from the last 5 decades, including the Jupiter Ace.
MESS emulates the hardware of the systems and sometimes utilizes ROM images to load
programs and games. Therefore, these systems are NOT simulations, but the actual emulations
of the hardware.
