At least in version 1.0 (press CTRL-V during game play >to check) there _IS NO_ quarter-track. You can tell quarter-tracks >with true Apple Disk II drives. You can hear a slight tick I don't remember if I saw quarter tracking, but my 5.25" copy of POP used the 18 sector format. Anyway, at least back then, you could send in the 5.25" disk and ask for a 3.5" copy, which is easy to copy: Prince of Persia 3.5" deprotect: Block: 7 Byte: $16 From: $90 (bcc) To: $80 (bra) Block: $A Byte: $8C From: $18 (clc) To: $38 (sec) This is to be used for archival purposes only. POP is indeed a great game with great graphics. Despite the 128K requirement and InCider's comment otherwise, it is just single hi-res. So is Wings of Fury if I remember right. I wish I had 3.5" version of that great game. (Enable the Visit Monitor CDA and use it to clear the hi-res screen while playing.) -- --Jay, jay.krell@cornell.edu
