BINSIC – my reimplementation of ZX80 or ZX81 (Timex Sinclair 1000 or 1500 for US readers) BASIC is now available for download in binary form – look at the page on the site: Binsic Is Not Sinclair Instruction Code.
It comes with Conway’s Game of Life for the authentic black and white text based feel too.
