Adrian from Adrian’s Digital Basement was given what superficially appeared to be a TRS-80 Model 4. But it also had suspicious signs it might be a mash-up of a Model 3 and Model 4. What he found inside was perhaps more mash-up than he could have imagined.
Laugh along with him as he spelunks his way through the digital artifacts he finds inside the machine.
After figuring out what all of this strangeness was about, Adrian thought he might get lucky and have the motherboard boot, but no joy. He’s not giving up though and will update his progress in a 2nd video.
UPDATE:
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
