Pins 1 through 34 are the same with the exception that pins 8, 26, 28 and 
30 are tri-state as opposed to open collector.  This means that ytou'll 
need to connect 10 Kohm pull=up resisters from these pins to +5v.  Pins 
37 through 40 are ground +5v, ground and +12v respectively.  This maps to 
a 'standard' power connector as

37-------------------- 2 (ground)
38-------------------- 4 (+5v)
39-------------------- 3 (ground)
40-------------------- 1 (+12v)

I pulled this info from CIS a while back.  It seems to work fine.

Hope this helps.
