Covox Sound Master

This was almost a proper ISA game card by Covox. It was one of (if not the first) Adlib clone. But it also included the Speech Thing circuitry. It had no audio input. It had two joystick ports, not for a PC joystick (of course, this is Covox). The ports were for Atari CX-40 joysticks or Sega Master System Gamepads only. Paddles, Mega Drive gamepads, 7800 joysticks, or anything that expected 5 volts to come from the port would destroy the card if plugged in. No, it did not tramslate Atari or Sega controllers to PC joystick data. Games needed to be written specifically for the CSM game ports. As an Adlib clone, it was not very good. Sound quality in Adlib mode was inferior to a real Adlib.
