From: fred@hpcvlx (Fred Taft) Subject: 6809 Disassembler Date: Fri, 19 Aug 1994 16:00:48 GMT When I first got my Vectrex, I spent Thanksgiving weekend writing a disassembler for the 6809. I then dumped the contents of several of the games (including the built-in OS/minestorm rom), and ran them through the disassembler; worked like a champ! Then I began the task of interpreting what I saw. I actually succeeded in reverse engineering the following games: Art Master Mine Storm Star Castle OS and utilities Memory map of OS and Mine Storm usage I even went so far as building a plug-in card for my HP Integral Computer, which also attached to the Vectrex. I could compile my tests on the Integral, download the bits to the card, and then turn on the Vectrex; worked great! The assembler I was using I picked up for free off of the net, and it had a few bugs. Unfortunately, none of this stuff has been touched for probably 8 years. Fred Taft fred@hp-pcd.cv.hp.com
