Tandy PC-1 / Sharp PC-1211 New LCD, Printer/Cassette Interface Refurb

Video sponsor: PCBWay: $5 for 2 layer PCBs with 24hr turnaround at https://www.pcbway.com/

In this video we fit a new replacement LCD in a Tandy PC-1 which is the same as the Sharp PC-1211. Thankfully someone is reproducing the LCDs for these vintage pocket computers. (Link further down.) Inside we’ll find a mystery bodge board.

We’ll also refurbish the printer and cassette interface. There is a crusty old battery pack to replace and some corrosion to clean up. Join us and see how we made out.
