	I'm having a small crisis.  I believe I erroneously clipped resistor 35
when performing a memory upgrade to 2.5 Meg.

	I was making 2 Meg upgrades to four of our department's Macs.  The last
machine was a recently acquired SE with two floppy drives.  The SIMM sockets
were a light biege -- first time I've seen that.  Upon powering the sucker
up the screen quickly came up with a checker board pattern with the flashing
question mark on the floppy image.  Normally it takes a while to perform
memory test.  Drats!  I forgot to clip the resistor 35(?) as required.   I
open it up, clipped the resistor and ...

	Same thing.  Upon closer inspection of the board I noticed that there
is a jumper where I don't remember seeing before.  Has Apple gone ahead
and revised the board by using a jumper instead of clipping a resistor?
(Without telling me?  :-)  If so, how should it be properly set for 2.5
Meg?  If not, any ideas as to what is wrong and how to fix it?

	As it turns out it's the department chairman's Mac, wouldn't you
know? :-(

	Please respond via e-mail.  I will summarize and post.

Thanks,

	joe piazza
