New Product: Digital Input / Output Board for TRS-80 Model I

Posted by El Hefe on 13th Feb 2025

We're happy to announce that our 32-Input and 32-Output board for the TRS-80 Model I is finally available!  It's been a bumpy ride to get here, but we have arrived, finally.

Here's a brief overview: This board hooks up to your TRS-80 Model I (either directly or to the Radio Shack Expansion Interface), and the board gives you 32 digital outputs that you can control using the BASIC command "OUT".  Similarly, it has 32 digital inputs that you can read using the INP command.

The board comes fully assembled with a ribbon cable, all you need is a 5V DC power supply and you're ready to go !
