The three chips pictured below found in the BC slot1 board contain key software at risk of preservation unless we act today.
IC3 is a 2mbit flash and contains the cpu code, according to the manufacturer datasheet it has a data retention guarantee of 10 years. IC107/108 are 256kbit eproms containing key system signals, their data inside will last 30-40 years depending on conditions.
If you would like to help preserve these please dump/read these chips and provide me a copy along with your CRT monitor model and year, BC board revision code, and software revision (menu->status). If you don't have a chip reader you can buy the inexpensive TL866II Plus from Ebay, IC3 will dump as AM28F020, and IC107/108 as any 27C256 eprom variant.

Thanks for collaborating in preserving such fantastic monitors.
