HC-55516
Continuously Variable Slope Delta (CSVD) Modulator/Demodulator. These are the high quality 14 pin ceramic DIP gold lead version made by Harris. There are two versions of Williams speech boards used in conjuction with the sound board in System 6 and System 7 pinball games. One version of this speech board has the MC3417L and the other version has the HC-55516. One of these two ICs will be found in games like Gorgar, Alien Poker, Blackout, Firepower, Jungle Lord and Pharoah. There is some confusion as to the correct part number of this chip. The prefix stamped on the part can be read as CI-, HCI-, or HC1. However, the datasheet from the Harris databook calls this part an HC-55516. The "-9" suffix indicates a commercial temperature range of -40C to +85C.

HC-55536
Continuously Variable Slope Delta (CSVD) Modulator/Demodulator. 14 pin ceramic DIP made by Harris. Used in Williams System 11 boards, and I also believe they are used on Bally WPC sound boards. The prefix stamped on the part can be read as CI-, HCI-, or HC1. However, the datasheet from the Harris databook calls this part an HC-55536. The "-5" suffix indicates a temperature range of 0 deg-C to +75C.

QVE11233.0086
Opto Coupler / Opto Interrupter made for Bally and Williams. There part number is 5490-13451-00. These are the high sensitivity optos that are used in 1990s era pinball machines. The optos inside the clock on Bally's Twilight Zone are one example of where these special part number optos must be used. This part has the additional ".0086" suffix after the QVE11233, which means that it has a higher sensitivity compared to a regular 11233 without the suffix. Regular optos may not work in 1990 Bally or Williams pinballs.

R6503 or SY6503A
Microprocessor, 28 pin DIP made by Rockwell. These ICs were used in early Gottlieb System 80 sound boards, for pinball machines like Spiderman, etc. The original Rockwell chip works at a frequency of 1MHz. I am selling the 2MHz version of this CPU chip made by Synertek which is a direct replacement. It has the "ability" to run at 2MHz but the actual clock speed is determined by the crystal on the PCB. Therefore, these chips will run at 1MHz when installed into your original pinball PCB. Synertek was a major competitor to Rockwell back in the early 1980s.
