Thanks to a couple of people's feedback the keyboard in jtyone http://www.zx81stuff.org.uk/zx81/jtyone.html should now work fine on PCs and Macs - and anything else capable of running javascript at a reasonable speed. I've tried an iPhone 5 and and Android phone and it ran happily at 50fps. iPads se...

Re: JSZeddy

I am trying to diagnose why the jtyone keyboard input on Macs is not working (I assume you are on a Mac, my PC keyboard works fine). Unfortunately I have no access to a Mac - if anyone has one and is willing to run the emulator and capture the console output resulting from a few keypresses I would r...

Re: ZX81 multi-platform emulator

I've put a lot of effort into optimising the emulator and can't see how to get performance any better. iPad seems to run about 75%; iPhone 4 is slow but iPhone 5 runs very happily at 100%.

Re: WIP - Why did the low-res pixel object cross the road?

Looks great, and an unusual perspective for a ZX81 game. This did ring a bell - not sure if you've seen this one, but a game from 1982 with a very similar look - City of Xon by Pleasantrees.

Re: ZX81 Stuff Updated

Thanks! I put quite a bit of effort into learning php, Javascript and CSS to get the site looking and working how I wanted, and to make it accessible to mobile devices. I'm very pleased with the emulator conversion to JavaScript and the touch-screen keyboard (took about 8 hours of pixel editing to g...

ZX81 multi-platform emulator

Just wanted to announce a big update to my website including a JavaScript-based emulator which should run on most platforms. I have tried it out on iPad, iPhone and a couple of Android phones and it seems to run fine (although a little slow on some devices). There's an on-screen keyboard for touch d...

Re: ZX81 for sale on eBay.fr

Thanks. I've contacted the seller, although given the error that I get I probably won't be able to bid on the item :-(
