Cheers to Zilog for sending me information on his project, divIDE. It's the system allowing you to load emulator files (tapes and disk images) from a FAT16 hard drive directly into your ZX. You may have seen it mentioned on raww.org in the past.
Well divIDE 42r2 (wasn't he a Star Wars character?) has been "released / published / documented". To quote Zilog himself: "Now it's open, fully featured, even smaller, in-system reprogrammable and ready to be produced". The system is to be written by Baze/3SC.
Unfortunately the site containing all the techy information is down as I write this. Hopefully it will be back up-n-running quickly.
