The official AT&T 1Meg upgrade for 5620's simply has you replace two things

	memory chips with 40256's

	one of the 74xxx chips with a slightly different version.
	(don't remember details; I think the new chip was an LS part)

Ages ago I had someone tell me they simply replaced the memory chips
and everything just worked.

Ages++ ago I tried using the official 1Meg upgrade to upgrade "my" 5620.
Oops..  didn't work.  And we didn't try tracking down what was wrong.
