I purchased my first computer, a Commodore 128, on August 19, 1985 (still have the antique). The C-128 did not have beautiful graphics like the ones you posted. Tron came out in 1982 and that was pretty big at the time but 3 years earlier than 1985. If you tell me that those images were produced by Adobe's Postscript language, I would be impressed (I believe Postscript was released in 1985). The mid 1980s were big on pastels -- was that an early storyboard for Miami Vice? (Yes, that was supposed to be a joke). Something to do with texture mapping? Z-buffer? Ok, sorry, it's time to spill the beans: Here's the ASCII in the TIFF files you posted: Looking at long hallway from afar (TEMPLE). 2006 JAN 14 10:34:37 EST Copied from file D:\apollo\quest2.img Looking down the long hallway (ARCADE). 2006 JAN 14 10:34:27 EST Copied from file D:\apollo\quest1.img Are these clues? 1) Is the answer in your book? 2) Were the images produced by an Apollo workstation? 3) Quest1 and Quest2: Was 'Quest' a video game? 4) Was the graphics engine based on a Motorola 68xxx processor? 5) Is this related to IBM's release of the VGA standard? Not sure how close to 1985 that was. Well, I'm out of guesses...tag you're it! :) Best regards, Ken Pergola -- View this message in context: http://www.nabble.com/-OT-Is-your-oldest-CD-R-still-readable--t907869.html#a2384618 Sent from the MicroControllers - PIC forum at Nabble.com. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
