#CIA's and stuff
I opened up my 2000 to make the CIA switch. I had to remove the mounting
for the power supply and disk drives to find the chips. This meant that I
had to unplug the disk drive bus and power supply bus.
To make a long story short, after I switched the CIAs and was plugging the
disk drive bus back into its plug, I noticed that a pin was missing and
that the remainder of the pin was inside the socket.
I tested the CIAs to make sure that they were definately not the cause of
my problems. I then opened the computer up again to see if I could fix the
pin in the disk drive bus, but I had no luck…I think the pin is too
short.
I think it is pin #4. The male connector on the printed ciruit board has
the missing pin on the left side, second from last (closest to the back of
the 2000). I think this pin is indirectly connected to the Gary.
My belief is that when the previous owner of my A2000 replaced the Agnus,
the guy at store snapped the pin. He probably tried to fix it like I did
to avoid replacing the socket, tried the computer and thought it was okay.
Sigh…I guess I must ask my Dad to replace the socket. I'm not that good
with the soldering iron yet. My last project (an audio digitizer) looks a
little metallic! I guess I should try anything myself on the mother board
