Guardian CPU buffer and DAT board

Introducing BoysonTech Guardian+ CPU DAT board with buffer protection.
  • Full CPU buffer protection built into the Guardian+ including NMI, HALT, IRQ, RESET, FIRQ, and DMA/BREQ lines.
  • Disable 2Meg jumper for non-patched Original Sierra games and other programs that only work with 512kB RAM.
  • Programmable Tricolor LED to illuminate the inside of your CoCo3.

The upgrade requires the removal of the soldered in Motorola 6809 CPU chip and replaced with a CPU socket. A machine socket is included with the kit.
It is highly recommended that the socket should be installed by experienced bench technician. The CoCo3 is a 30 year old computer and can be easily damaged by an inexperienced person or by improper solder equipment.
Professional installation is available - contact BoysonTech for details.
