Can anyone help me identify the cause of the following problem(s)?
Configuration: Mac SE upgraded to 2.5m, Sys 6.03 (I think)

Last night, the mac would not start up: sad mac code 0000000E,
000000FF. (Data bus failure, right?)  I used to get this top
line occasionally, but this is the first time since I replaced
the 1 meg SIMMS.  And it had a different bottom line.
This morning, the machine starts up fine, (in Multifinder, BTW).
I go to About Multifinder to check the memory. Total memory is 
fine, but the system heap number is switching between (I think)
561 K and 565 K.  (Whatever the actual numbers were, I am sure it 
was a 4K block).  The "largest available block" was increasing and
decreasing as well (every 2 seconds or so). I could not investigate
further, as I had to come to work.

Are the problems related? In any case, what's the deal, particularly on the 
second. I am pretty computer and mac literate, but haven't used
multifinder much, so the system heap business has me a bit puzzled
in general.

Many thanks.  E-mail encouraged.
