About the resistors. The people (many) who gave me instruction on how
to do it all mentioned resisitors needing to be put in. On the REV D
board there are 4 68-69ohm resistors as follows
-***-
-***-
-***-
-***-
and then 9 or so 330ohm
-***-
etc.
The two I put in were in that space there in the 4 and underneath the 4
68-69 ohm type. We looked at a 1040STf REV B board (which is totally
laid out on the board differently -- RAM, not ROM under power supply,
CPU not on right, etc.) and it two had 6 (not 4) 68-69 ohm resiistors
and 9 or so 330 ohm resistors with the RAM. Someone told me the resistors
are there to be nice to the MMU chips and that some early 520 ST models
didn;t have them but they do now.
We are going to first try reseating the MMU and then try to get one.
(anybody have one cheap???)
