Since writing the PBI BIOS for the Ultimate 1MB and Incognito in 2012, I found myself increasingly focused on developing original and re-implemented firmware for hard disk host adapters, culminating in a ground-up re-write of the entire U1MB ROM firmware in 2015.
As of April 2020, the firmware has reached version 3.10.
