certain positive identification of powerbook ram card?..


Well-known member
so I have a 1993/1994 silk-dated apple 820-0455-A populated only on one side (other than for the 70-pin connector header on other side) and just for further confirmation it has eight of these nec D42S4800G5 -70-7JD chips, so question is is this the 8mb variation of a 8mb/16mb card option for powerbook 5xx's yes?

and just curious but would that be like 70mhz ram or did the suffix numbering come to mean something different?
