The unfinished “How Many Can You See?” screen from the abandoned Hellbender demo that we were writing together in ’92/’93.  This is a “4 in 1” demo screen that features four mini demos in each corner of the display.

Top Left = Multi colour pixel perfect horizontal sine wave scroller

Top Right = Multi colour sine wave logos (this should have had single plane “GBP” sprites bouncing around too, but never got added)

Bottom Left = Traveling landscape (this should have had 3D balls bouncing around on it)

Bottom Right = Multi colour & multi line sine wave text

Neil Halliday

Neil started coding in STOS in 1989 just after it was released in the UK.

During those 31 years he has written numerous demo screens, routines, games and extensions, most of which are now lost due to a massive hard disk crash. What remains on floppy disk is still being discovered and posted on the STOS Coders website and stored in the cloud for everybody to enjoy (or laugh at).

Neil is the author of the GBP Extension which added some pretty cool commands to STOS, along with the "Development" extension that enabled enhanced STE functionality, including probably one of the simplest hardware scrolling routines around.

Along with Bruno Azzara, Geoff Harrison and Mike Halliday we had loads of fun back in the day trying to push STOS to it's limits. We are all now enjoying bringing our knowledge to a new generation of STOS Coders.
