Its publisher, David Horne , would go on to publish the code for the program in a three art Computer Magazine series (the first part of which you can see embedded below: This is the super-rad David Horne: 1K ZX's 33 year reign has just been challenged. The challenger is a program called BootChess, which includes all of the features of 1K ZX with a stunning memory allocation of only 512 bytes. The program was written by Olivier Poudade and Peter Ferrie . It was never a very graphic-intensive game, anyway This is a photo of Peter Ferrie: A photo of ...
