Yes it does. 
Home switch, reverse direction, index pulse, 2 times speed to home, and back 
the sxis offset.

I am not aware of a jumper on the STG board that affects the index pulse, but 
correct my if I am wrong. 
I just tried to open the stg2 hardman.doc word documentation file with 
staroffice, but it does not work :-(
Please contact Don McLane about this to be sure. Or download it yourself at

CPU AMD K6-2 300 MHz here.

Try to decrease homing velocity, I the index pulse found under slower speeds ?
Have you tried to debug with the diagonstics macro ?
Can you see the index pulse when you connect to the index port/wire with on 
osziloscope ?
