11. TheMUX chip selects each joystick pot input line and applies it to the plus input of comparator IC LF353 At the same time the MPU generates digital words that are changed to voltages by the DAC and current voltage converter mentioned previously These voltages are successfully applied to the comparator s minus input until the MPU generated voltage is equal to the joystick voltage The MPU then recog nizes the digital word representative of the comparison voltage and is able to establish a location for the joystick pot The present position for each joystick pot is sensed in this manner The pot position information is updated on a regular basis by the MPU Returning to the X and Y axis drive signals these signals are applied to X Y integrator IC LF347 negative input pins through series analog switch types 4066B The zero reference signal is applied to the positive inputs of the integrators There are also analog switches across the integrator IC capacitors The series analog switches are controlled by MPU signal RAMP andthe parallel capaci tor switches are controlled by MPU signal Zero 10 RAMP 10 determines when and for how long the X and Y axis voltage levels will be applied to the integrator amps Zero 10 is used to discharge the X amp Y axis integrator caps thus initializing them for the next signal to be integrated The outputs of the X Y axis integrators are coupled through J FET switches to IC LM379 deflection amplifiers The LM379 operates
12. as a voltage to current driver the current through the deflection coils forming the electromagnetic field which deflects the CRT beam To protect the CRT from spot burn in the event of a loss of deflection the Y axis drive amplifiers output is detected and a deflection enable disable signal generated This signal controls the J FET switches in series with the X Y deflection amp inputs to reduce the scan drive signal in the event of a software or hardware failure plus discrete transistor type 2SC1921 operates to bias off the CRT Conventional full wave rectification and three terminal regulators are used in the low voltage power supply A special negative DC source is generated by a voltage double circuit which is used to supply a 13V to the DAC chip The high voltage is generated via an oscillator drive transistor and flyback type transformer cir cuitry similar to what is commonly used in small black and white TV receivers Judicious use of bypass caps RF filter chokes ferrite beads etc has been used in the design to control RFI emissions G3GO1dX3 X3H193A G POODEL ISVO LNOH4 Ol LNHB V O M3HOS 1 6 10009 OJJA ASSV 318VO el 1 690001 ASSY L4 H8 82d DOTUNV IWIIDIO Li 6 1009 o anv ASSY 31890 0t prooort ISV LNOH4 1388 HMd M3HOS 6 1 680001 ASSY 1330V H8 929 H3MOd 8 1 600001 ASSY 3SV2 1NOHJ t 200066 ASSY H311OHLNOD 9 44O NO 3WNI0A BON 5 d 10 8ONDI v ZOOOEL ASSY 3SVD INOH3 L 2v8 M3HOS
