RAM is read/write random access memory.? Power goes off, contents vanish.? EPROM is erasable programmable read only memory.? Power goes off, data stays.
RAM is the arduino's ram memory, EPROM is two varieties in an arduino, and is either the EEPROM, or the FLASH memory program storage.
Chuck Harris is to be found on the Tekscopes2 forum.

Hi Mark,
Thank you for your response. What you have suggested is interesting and may well work, but it is way over my head. I have no computer programming experience (other than a bit of dabbling with Arduino stuff). Not sure if what you are referring to as the EPROM is the same as the RAM chip (which in my scope is an NEC D4464C-15L chip).
It would be terrific if I can find a way to write the cal data via the screen. I recall reading in one of the posts from Chuck Harris on this Forum where he appeared to imply that it was possible to do so, but no details were forthcoming. I am hoping that Chuck will respond and clarify the issue.
