Pixel Plotting in ZX80 Basic

Post by TheSnial »

For fun I wanted to reproduce the Jupiter Ace sine wave program on a ZX80 in BASIC. ZX80 Basic of course doesn't provide PLOT or UNPLOT, the display is inconveniently after the workspace and variables (so you can't just cache the start address) and the block graphics character codes are in a wacky order, but eventually I managed it :-)

I like it, that's the classic way to do advanced stuff in the 8bit age and get published on magazines !
