The final part of my quest for 8 MB of RAM on my Radio Shack TRS-80 Model 16B! In this video, I modify the 68000 CPU card for the MMU upgrade, install the MMU, and test it out. Music (in order) “Elevator Music“ (Digital Juice, used under license) Chapters: Intro (0:00) Installation / Test I (1:46) 68000 CPU Board Modifications (0:56) CPU Removal and Burndy Sockets Suck (3:50) Installing MMU and CPU (6:32) Jumpering the SRAM Board (7:06) Moment of Truth (7:43) Outro (10:56) I do these videos unscripted, so I apologize if the in-the-moment descriptions of things are a bit scattered. If you have any questions/comments about this video, you can find me in any of these fine locations: The Tandy Discord Server The CoCo Nation Discord Server The TRS-80 Color Computer (CoCo) group on Facebook The CoCo Crew Podcast group on Facebook On the Vintage Computer Forums () The TRS-80 Models I-4/4P Group on Facebook Tandy /
