Hi Bill,

There are two types of SE's. Resistor models and Jumper models. For the 
Resistor model, you have to clip the resistor; for the jumper model, you 
have to remove the jumper. Do NOT clip the resistor if you have a jumper model!

According to the handbook "technology Works Memory Upgrade: Installation 
Guide" (1990):

"If you have the Resistor Model, the logic board will be marked 
"820-0176-A" or "820-0176-B" just to the right of the 68000 processor. 
Above SIMM 1 on this model there will be a box marked "RAM size" stenciled 
in white on the motherboard. Within this box there will be a resistor 
marked "R35" and a blank space labeled "R36".

After installing the RAM, clip R35 on one end and bend it aside to prevent 
contact.

If you have the jumper model, the logic board will be marked "DIP SIMM MAC 
SE, 820-0250-A, 1988, 630-4250" just to the right of the 68000 processor. 
Above SIMM 1 on this model there will be a black jumper with "1M  2/4M" 
Stenciled in white under it on the motherboard.

After installing the RAM, remove the jumper completely. If you wish to 
store the jumper [for later conversion back to 1 MB], you may place it over 
just one of the jumper pins so that no two of the pins are jumpered. NOTE: 
although there is also an R35 resistor on this model DO NOT CLIP IT!

I did a RAM upgrade a couple weeks ago and it was easy-peasy, even for my 
all-thumbs self. If you need help, give me a call at 207-786-8248.
