Compaq Deskpro 386/20e VGA Connector?
I just got a very nice, maybe never used, Compaq Deskpro 386/20e computer
from Ebay. Except for the big scratch on the top that the seller never disclosed it looks great. Even came in original carton and had brand new keyboard and sealed software/documentation! Boy was I surprised however when I went to hook it up to my new Viewsonic E70 monitor. Apparently, Compaq used a keyed VGA connector that has no hole for pin 9. My monitor has a pin 9. Anyone have any ideas? Is there such a thing as an adapter that will allow a 15 pin VGA male to connect to this computer? Do I need to get an ISA video card? Will that have the same problem? Would it work with this computer? I HAVE been able to hook up my IBM PS/2 Model 30 286 to this monitor. Both computers are around the same vintage (~1990). Thanks. Mark |

Your monitor isnot supposed to have the pin.
Are you sure the cable isn't installed backwards? Tom "Mark" wrote in message ... I just got a very nice, maybe never used, Compaq Deskpro 386/20e computer from Ebay.

I might be going crazy, so I'll check again. But I'm pretty sure the
connector has the pin. I also looked at my girlfriends monitor today and it didn't have any missing pins either. If I don't post again it means that the pin IS there.

Oh, I believe the pin is there. Many monitor makers stopped removing the
pin, as computer makers stop keying the plug. The problem is that the 'standard' such as it is at the time of that machine had a keyed connector. That pin isn't used. Worst case, you should be able to find a cable without the pin. If you're adventursome, break off the pin. Not recommending that though, as I don't know if the pin is really used now.

Yeah, I think you're right. I looked at the "standard" pinout and the pin
isn't used. Must be as you say, they just stopped removing the pin. Unfortunately I think my VGA cable is hardwired into my monitor. So, unless there was an extension cable that didn't have a keyed female but did have a keyed male, I'd be out of luck. And, I really don't want to mess with the new monitor. I wonder if I can poke a hole through the female connector on the computer. LOL Open to any ideas. Mark "Tom Scales" wrote in message . .. Oh, I believe the pin is there.

Actually, in newer connectors (with blue overmold) the pin IS supposed to be
there, carrying 5 VDC to power the DDC (Plug-n-Play comm. channel) even if the monitor is off. VESA adopted that in the mid-90's. Since this is a '90 vintage machine, I expect you'll never want to run any up to date OS with P-n-P, so it's likely OK to just remove the pin (if you can without munging anything else). Or, if you *do* want to install win95/8, just be aware that you will always need to turn the monitor on before you boot they system. HTH, NGA "Mark" wrote in message ... Yeah, I think you're right.

Buy a cheap extension cable. Break off the pin on the extension cable, not
the monitor cable. Problem solved! Tom "Mark" wrote in message ... Yeah, I think you're right. I looked at the "standard" pinout and the pin isn't used.

Thanks everyone. I learned about this VGA connector in the process of this
problem. Yes, I'd like to buy the cheap cable, but when I find one it says it will only work for smaller than 17" monitor...who knows why! I don't want to remove the pin from the monitor because I use the same monitor for my new computer. I might be able to use two gender changers back to back. It does appear that often both the adapters and extention cables don't have the keyed female but do have the missing pin 9. So, one way or another I'm sure I'll work this out. Thanks again.

Thanks Tom. From the picture, no cutting of pins will even be needed. :-)
