This is another disk from Trevor Taylor, showing off the capabilities of the "Multi Peripheral Interface" hardware. This apparently supported up to four joysticks, an AY-3-8910 sound chip, soundware-style sound generation, and a light pen. MENU.BAS -- Draws "Micro Tech" in cursive, "Multi-Peripheral Interface Demonstration Disk" Then launches all other programs. PATCH.BAS -- PAT16.PRG -- PAT32.PRG -- These form a modified soundware patch routine. Rather than doing the patch relocation via conditional logic in the byte poker, one of two pre-cooked patches is loaded from a file. "PATCH.BAS" is not self- contained, as it ends with "GOTO 150" which there is none! SWDEMO.BAS -- SOUNDD.BAS -- SOUNDI.BAS -- a demo launching program, modeled on the Soundware menu programs. It invokes SOUNDD.BAS and SOUNDI.BAS, which are identical to their intro_to_soundware.ccvf form, but no sound comes out because the driver patch apparently hasn't been installed. Hmm, the code does appear to attempt to load one. TTTWO.PRG -- pong. this appears on a number of other taylor disks. DOGFGT.PRG -- WW I biplane dogfight. this appears on a number of other taylor disks. Many of the following files appear on interface_software.ccvf as well, although at different file revision numbers. DTHRAY.PRG -- DEATH RAY, (c) 1981 Trevor Taylor requires a joystick to play. it is very similar to his game DOGFGT (dog fight). LASER.PRG -- when run on the emulator, it doesn't respond to input and it continually fires its laser. Perhaps it is specific to the ISC 3650. TT2J.PRG -- table tennis for two, ie PONG. it runs, but isn't playable without a joystick. LPDRAW.PRG -- draw with a light pen MNUTST.BAS -- menu selection via a light pen FREQ.BAS -- FREQ3.BAS -- explore parameters for generating tones with the AY-3-8910 JOYPLT.BAS -- JOYTST.BAS -- joystick calibration routines SOUNDD.BAS -- SOUNDC.BAS -- These are demo programs off of intro_to_soundware.ccvf
