Guy,
That is pretty cool. So now I know if you don't mind I am going to pick your
brain a bit: Were there two revisions of the 5322?
I ask because I have two 5322s and while very similar they differ in at
least two areas: The older model seems to have a linear PSU and socketted
chips vs. the newer one with switching PSU and soldered in chips. Just
wondering. Thanks.
Yea, there were lots of under the radar changes especially early on as things got
figured out. The original, original PC had 16KB soldered down and then the next
48KB was in sockets. I think once they figured out that most folks needed more
RAM, they just populated 64KB and did away with the sockets.
