<snip> Hi, For the video pinouts, take a look at http://www.classiccmp.org/pipermail/cctalk/2001-July/176233.html. To repeat part of that thread, the signals come from the bottom of the edge connector on the front panel and the shunt carries them to the top, where they go to a single inline connector that connects to the monitor. Looking at the edge connector from the front (numbered right to left, odd on top, even on the bottom), the signals are: 2 Ground 4 Brightness High 6 Brightness Low 8 Brightness Arm 10 Ground 12 Horizontal sync 14 +12V 16 Video out 18 Vertical sync 20 Ground The shunt just connects the top contact to its mate on the bottom: 1 to 2, 3 to 4, etc. There is/was a pdf of the Osborne 1 Technical Reference manual online. I don't have a link handy, but it has been posted before, so just search the archives. Bob
