TRS-80 Coco 1 Repair and Mod - #SepTandy 2020
About this video
Never-opened since new, a TRS-80 Color Computer gets a keyboard repair, a composite video output mod, a motherboard recap and a clean, with chapters for each job.
Good to know: Mains voltage may be present inside the case, and capacitors can stay charged after unplugging. Soldering brings burns and fumes; old solder contains lead.
Why watch it
Chapter markers split the work, including a stretch at 15:17 on whether the board is 64K or 32K, and the composite mod design is explained before it is fitted.
