Can I repair TWO Commodore Plus/4's with one spare motherboard ?

TWO Commodore Plus/4 computers and one complete motherboard. None is working!
PCBWay kindly sponsored this video https://pcbway.com/g/sh5u2D great quality PCBs from just $5!
In this video, I take a look at a two non-working Commodore Plus/4. One has a character fault and one shows no video output at all. Is it the TED chip? A bad ROM? Something worse? Join me as I try to bring these classic 8-bit computers back to life using a diagnostic ROM and some methodical troubleshooting.

If you enjoy retro computing repairs, chip-level diagnostics, and classic Commodore hardware, this one’s for you.
