Time to pull out the octoinfo file, which shows three different
notations for setting the jumpers; hope you can figure it out...

1. Jumpers indicated by "xxx":

   	256K SIMMs:	1	2	4	8
	Switch 1      xxx     xxx     xxx       xxx
	       2      xxx     xxx     xxx     xxx
	       3      xxx     xxx     xxx     xxx
	       4      xxx       xxx     xxx     xxx
	       5      xxx     xxx       xxx     xxx

   	1M SIMMs:	1	2	4	8
	Switch 1      xxx     xxx     xxx       xxx
	       2        xxx     xxx     xxx     xxx
	       3        xxx     xxx     xxx     xxx
	       4      xxx       xxx     xxx     xxx
	       5      xxx     xxx       xxx     xxx



2. Meaning of each switch having a left or right jumper:


			LEFT		RIGHT
	Switch 1 			SIMMs 5-8
	       2 \      /256K  \	/1 Meg \
	       3 /      \ parts/	\ parts/
	       4        SIMM 1		SIMMs 1-2
	       5  			SIMMs 3-4



3. Meaning of each of the possible left/right jumper settings:
