This is good info. Someone should post it as a
mini-FAQ.
Feel free...
Do you have any info on which ones used 7 bit refresh and which ones used
8 bit refresh?
I probably have the info somewhere, but I can't remember where (so I
might as well not have it!). All I can suggest is to try it. It won't do
any harm if you use the wrong sort of chip. If it works, then either it's
a 7 bit refresh type, or an 8 bit refresh one that still refreshes the
part you're using conrrectly.
