From the project
A range of gadgets that can be plugged in to the PAL-1 RIOT Expansion Module to provide specific functionality.
The PAL1-IEC gadget is an IEC/Serial adapter for the PAL-1 system intended to plug in to the PAL-1 RIOT Expansion Module.[^1]
The IEC gadget allows Commodore disk storage devices and printers to be connected to the PAL-1. The schematic is based on an original design by D McMurtrie.[^2]
