Lots of progress on my work-in-progress Battlestar Galactica "Cylon Attack" game. I eliminated the flicker on the Cylon from my part 3 video. Root cause was the Tektronix 4050 BASIC command to get the Tektronix joystick position digitized uses the display X and Y DACs (digital to analog converter) which keeps the Option 30 coprocessor from displaying the Cylon.
So I designed a new joystick interface using unused pins on my GPIB Flash Drive. Two of the pins are connected to my Vectrex video game controller analog joystick and four pins are connected to the four buttons on the Vectrex controller. I added code to the Flash Drive to send the X and Y joystick analog values plus the four buttons back to BASIC when the program does INPUT@5:31:X,Y,A,B,C,D to request the gamepad data.
This video uses the gamepad button 4 to fire at the Cylon, and I have added code to my program to randomly move the Cylon around the screen.
