Though it doesn't cover all of computing history, this site is a comprehensive timeline of personal computing history from 1947 to now.

Apparently the author has been maintaining that timeline since 1995 and is still doing it!

While it doesn't cover things like computer science, I think it's an excellent jumping off point for learning about notable people and events.

Not exactly what you asked for, but you may also be interested and may give you some insight I think more programmers should have.

EDIT: Also, don't stop at Babbage & Lovelace. Although Babbage's analytical engine was one of the first, if not the first programmable computers with a form of memory, there were people working on extremely primitive computers (or rather advanced calculators) way before Babbage. Schickard, Pascal, and Leibniz conceived of and developed calculating engines that did basic math with support for interim value storage, which one might consider to be the earliest form of computer memory.
