ST-412 Jumpers

I'm just trying to figure out the jumper settings on a ST-412 drive. I've read the manual and it sort of helps, but its somewhat obtuse in style. I have two drives which are taken from working PDP 11/23's - they both have the same setting on the jumper block. The jumper block is a 16 pin DIL socket, with a 14 pin DIL plug inserted. The plug has 7 metal bars, 3 of which are open circuit, the rest are closed. Working from the connector end of the PCB, the first bar - open second bar - open third bar - closed fourth bar - open fifth bar - closed sixth bar - closed seventh bar - closed Looking in the manual the first bar would persumably be written as 8-9, the second as 7-10 etc? Anyway, I'm trying to use this in a PERQ just to test the EIO is working, and I can boot of floppy. So I need to set this as drive 1. What bars would I need to open and close? Thanks Ian. ____________________________________________________________________________________ Yahoo! oneSearch: Finally, mobile search that gives answers, not web links. http://mobile.yahoo.com/mobileweb/onesearch?refer=1ONXIC
