A Casio Pokécom Compendium, fixing up a collection of Casio pocket computers

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

In this video we take a look at some Casio pocket computers in my collection that still needed some sort of TLC. The first order of business was to #GTDBO (Get The Darn Batteries Out), then we’ll concentrate on three different models which have three different issues. We’ll dissect an LCD, build a battery pack, and attempt a internal RAM upgrade. How did we make out? Join us and find out!

Timeline:
00:00 – Welcome
02:23 – PB-100, LCD dissection
12:23 – FX-820P, new battery pack install
30:59 – FX-840P, internal 32K RAM upgrade attempt
49:16 – Wrap up. Thanks!
