This document outlines the procedure for updating the KA50/KA52 CPU firmware, last updated in August 1993. The process involves booting the update program from a chosen medium (tape or CD), following the console prompts to flash the FEPROM, and performing a system power cycle to verify the new firmware version. A troubleshooting note mentions the use of an update enable jumper on the CPU motherboard if update issues arise, with a diagram provided for installation.
