I hope I have chosen the correct group for this problem.

I have a Mac Plus which has been showing some erratic behavior.  
On startup, periodically I will get the SadMac icon with a variety
of numbers.  The most frequent (repeated the last three bombs) has 
been 03FF00.  I am unable to identify what this indicates.  I thought
the 03 meant a memory problem, but my listing of codes does not 
indicate what the FF00 would point to.

Of importance, I have a Supermac 2Meg upgrade that was installed in 1987,
and I am on my third power supply board (replaced 1 year ago).

I am also having a real problem with the machine when trying to insert
a disk.  If the machine has just been turned on, disk insertion (it normally
starts from an external HD) will cause a system bomb (ID=02, or sometimes
03?).  Frequently, insertion will also cause a reset, periodically followed
by the infamous SadMac.  Restarting, and then inserting a disk usually
results in normal performance. (but not always :-(...).

My first suspicions of the cause(s) is the memory board.  Since I have
been considering an upgrade, I want to insure that doing that will cure
the problem, and not be money down the drain (sure, I can use the memory
in another mac, but my other mac is a portable...).

Any and all help would be appreciated.  It can be posted here, or to me
by email.
