Im going to do a mac SE/30 hack (battery powered, portable.) and im going to need to figure out the pins on the power/video connection. (going to replace the monitor and power board.) Im also going to have to make a 9 pin VGA to SE/30 video adapter of some sort. (for a screen like http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1722295102) Any idea where to start? |

Well, you need to pinouts for the SE/30 video, if you can get that to the standard mac DB-15 tyhere's no problem: you can get a cheap VGA adaptor for it.~Coxy - Leader, Tactical Operations Unit

fuggeduboudit! get a PDS video card! don't think you're going to get VGA off that board!from Guide to the Macintosh Family Hardwareby Apple Computer Inc.

Like the Macintosh II Video Card, the pseudo-slot video has a declaration ROM containing a video driver and initialization routines. Because the pseudo-slot video in the Macintosh SE/30 supports only the built in black and white monitor, it does not need a programmable video timing controller or a color look-up table.
i'm pretty sure the PDS cards that supported grayscale on the internal and color on an external monitor supplied those two components for the internal circuitry via the PDS as well as the full-blown video interface required to drive the kind of monitor you want to externally. the system patch to work around the built-in's ROM based driver and initialization routines would be your biggest hurdle, i would think.i'd look for a PDS card and see which circuit i needed for that eBay monitor and break the other one out to an external connector. i think that one of the links on our site or in my links project may have info on the signals (pinouts sounds a lot easier than i think it should is in this case!) for the SE/30's video, but my brain just went offline, so i'm not sure! good luck! jt  ™
