Prodest PC1 : Pinouts
Video 1 contains various signals which can be used to connect the PC1 to a television. Pin numbers are given for creating a PC1-to-SCART lead.
|Pin number||Meaning||SCART pin number|
|4||Ground||5, 9, 13, 17 and 18|
|7||Composite video||not connected|
The mouse port is for a quadrature mouse, like the one used on Amstrad's early PCs. However, the pinout is different. This table lists the pins, including pin numbers for a lead that can be used to connect a PC1512 mouse to the PC1.
|Pin number||Meaning||Amstrad mouse pin number|
If ENA is not pulled low, the PC1 assumes a joystick is connected to the mouse port. It's possible that a standard Atari pinout is used in this case.
