It's time to upgrade my 512K CoCo 3 Tandy Radio Shack TRS-80 Color Computer 3 to a whopping 2048K and also install a Pro-Tector+ MMU board to protect my Hitachi 63B09E CPU then play the awesome retro game King's Quest by Sierra Online! Let's go vintage technology!

The TRIAD + 2028K SRAM upgrade board runs 90% cooler than other memory upgrades, uses 1/20th of the power and it's also half the size! Note to use this memory upgrade board you will need the Pro-Tector + with MMU. Without the MMU version, your CoCo 3 will only see 512K.

Using the Pro-Tector + board in your CoCo 3 all lines are buffered and protected, not just the address lines, giving your microprocessor the best chance of surviving jolted multi-paks and cartridges. It protects the address, E, Q, FIRQ, Halt, IRQ, NMI and R/W lines of the 6809/6309 CPU.
