This is a collection of games, and some of the source code, by Trevor Taylor. These games require the use of 3rd party joystick hardware. This game must be booted on a system with v8.79 ROMs, otherwise even the menu doesn't work! ABM.PRG -- This is a clone of the Atari arcade classic, Missile Command, written by Garry Epps. Without joystick emulation, it isn't playable. Requires v8.79 ROM. The joystick is used to set the target, then one of the following keys is used to shoot a missile: Q - fires from the left base W - fires from the middle base E - fires from the right base DOGFGT.PRG -- World War I dogfight. It isn't playable without joystick emulation. Written by Trevor Taylor, (c) 1980 TT2J.PRG -- Table Tennis for Two (PONG), by Trevor Taylor, (c) 1980 Unplayable without joystick emulation. LASERJ.PRG -- Laser Gun, by Trevor Taylor, (c) 1980 Unplayable without joystick emulation. GHOSTJ.PRG -- Ghost Crunches, by Guy Larri, version VJ1 This is a PACMAN clone, but using joystick input. It seems to run OK under both v6.78 and v8.79 ROMs. Unplayable without joystick emulation. It seems Taylor took a stock game and patched it, with the patch in JOY.MAC and JOY2.MAC. JOYPLT.BAS -- x-y joystick test, one at a time JOYTST.BAS -- x-y joystick test, all four at once SNDGEN.BAS -- sound designer for AY-3-8910 This sound chip is not emulated, so this won't do anything. FREQ.BAS -- generate a simple tone using the AY-3-8910 chip. This sound chip is not emulated, so this won't do anything. The rest of the disk is filled with assembly language source for Trevor Taylor's programs. SNDCHP.MAC indicates: - the AY-3-8910 address reg was located at 30H - the AY-3-8910 data reg was located at 31H JOYUT2.MAC indiates: - the joystick ADC X value was located at 0A0H - the joystick ADC Y value was located at 0A1H - the AY-3-8910 was at 0B0H SND.MAC indicates: - AY-3-8910 address register is at 0B0H - AY-3-8910 data register is at 0B1H Ah, FREQ.BAS sets up "SA" (sound address?) and "SC" (sound control?) And says: SA=176:SC=177:REM FOR INTECOLOR 3650 (48 and 49 on CCII) These match exactly programs on joystick-sideA.ccvf: DOGFGT.PRG LASERJ.PRG TT2J.PRG
