Jupiter Ace Emulator

Do you remember the Jupiter Ace ?

I cant say I did at the time it was released I was 9 years-old and entering the world of the ZX Spectrum and as with many people it passed me by, But now some 30 years on I wanted one to play with on one...but they are way out of my price range!... then I finally managed it, Wow You say!... hmm it wasn't that simple I had to write it first! ... the first Ace I saw running was this emulator ...after days of blood, sweat & tears, but mainly tears ( not the joyful sort )... I booted it for the first time and nothing.... all went dark! An entire black screen.. So I rebooted, checked the code, rebooted again and again... a lot more hours later unable to spot the bug... I rebooted the emulator and just left it on and a short time later a small white block appeared in the bottom left corner, hmm interesting ... so I pressed a key and it was ALIVE!!!! I had greatly over estimated the potential boot screen of the Jupiter Ace, it is somewhat more minimal to non existent ... and the little white square well that's the cursor! - Enjoy.

Real JUPITER ACE Hardware

This wouldn't be very accurate emulation if we didn't test it against some real hardware and "we want accuracy, right?" - So after digging deep in our pockets - we found that wasn't enough.. after begging, digging deeper, no I mean really deep! We finally had access to a couple of real Ace's for testing, although the kids had no food, clothes or holidays, They'll enjoy the emulator too... { update: apparently not } well its all in the name of science of course... !

Our 3rd test machine will be built by hand, to the original PCB/ Circuit & Components of the ISSUE2 JUPITER ACE, We will add progress and info to the site when we can, its a very long process.

So here we are, For those that never owned, wanted, or now can't afford a real Jupiter Ace!
Plus those that paid out for their Ace and are too scared to use it or cant be bothered setting it up and taking over the TV or just don't have the an array of add-ons .. 3 Ram Packs, Real time - Debugger, Z80 Assembler, Instant Load & Save, Keyboard buffer, Convert a Text document to Forth, Access a hard drive tape library and load a tape in seconds, its for you too.

Other related projects

It would be better to have a greater number of research machines but they don't grow on trees and are rarely offered for sale, So we are now attempting to build some using the original design.

Along with building the emulator we started a few other related projects and when ready will be released for public use - we are working hard... time and funds permitting.
