WHY --- In the 80's the game was ported from the Sinclair ZX Spectrum to the BBC model B and Commodore Vic20. When I got a Amstrad CPC 6128 in 1985 after a 48K Sinclair ZX Spectrum, I was very dissapointed not being able to play JETPAC on the CPC, one of my favorite game. Along years, I have always keeped in mind achieving this child dream.
