My Headland HT-12A based 286 board has 2 American Megatrends branded bios chips in the standard Odd/Even configuration. I'd like to back them up using my TL866 but none of the numbers look like prom numbers:
1st Line is a date code and AMI
2nd Line: 286E-0 A
3rd Line: #C18864
4th Line: 764-117250-020D
Any ideas of how to read these chips safely and what modern eproms (or eeproms) might be compatible?
