Headland Technology Video Card 650-0216

I have a Headland Technology video card, 650-0216 and would like to know how to configure the DIP switch settings for my application. I would also like to know if I need to configure the jumper too. I am running it on a Pioneer Computer Inc. Vantage 80386SX-20 motherboard with a Sony LCD flat screen monitor plugged into it. When I turn on the system I get no display but I'm sure it's cycling through it's initial startup sequence as the drive cycles and the keyboard flashes along with a series of beeps. Any help with the video would be appreciated.

Well, that's some pretty old sounding equipment, from your description, and looking up just what video card you're talking about. However, your screen sounds new. I would question whether or not your screen can work with the output from that card. It has the D-SUB 15, 3-array connector that has been standard for VGA, but could it be an old EGA adapter, or something with more proprietary signaling?

If at all possible, is there an older CRT style monitor you could attach to the output on the graphics card, to determine if it's just incompatible with your newer screen?

I'm afraid, without knowing what the DIP settings are for, there's nothing I can offer you as toward how to set them.

Thanks! Getting an old CRT monitor is probably the next logical step...

Well, if there was one you could try the system on, I would do that before I put much money towards it, as it may not be the solution.

I've been doing some reading and I believe my video card is incompatible with my new LCD monitor. My video card most likely uses the older VGA standard to transmit it's digital signal while my newer monitor is expecting a signal conforming to a DDC type. So basically it can't translate what my card is trying to send it. Maybe a computer hardware engineer could explain it better.

As far as the DIP switch setting goes I guess I could use this chart in a trial and error fashion. I just have 255 other possible combinations... :-D

Well, yes you have 256 different combinations for your DIP switches. The problem is, not knowing what they do, you may be getting results and not knowing it. On the other hand, you could also damage the equipment without knowing it, if they deal with any sort of voltage levels or control things such as any add-on memory for the card.

Presumably, the card worked when it was last used, so you might want to start your attempts at getting it to function, using the last state it was left in, without changing any settings yourself, unless of course you know that people have fiddled with the settings between it being last used and your acquiring it.

Concerning the VGA signal that should be coming out of that card when working, it's actually analog at the output, not digital, and uses timing signals. Your new screen simply may not be able to sync to the older timing signals. If that's the case, it may display an error message or simply remain black or off.
