Design files for a remake of the PDS Programmers Development System
This contains the hardware design files for the PC ISA interface card for the PDS. Largely based on the designs detailed here: https://www.cpcwiki.eu/index.php/PDSdevelopmentsystem
Although as per my post here, I don't believe the schematics published here are correct.
Please refer to the main repository readme for licensing, copyright, and limitations of use.
