Heya,

I have a full tower AT-form case which is being used for another project here I've posted about.

It has the LED screen (not LCD, the one made of LED segments) which I would like to set to display "4" normally and "8" with turbo button pressed. The turbo button connects to the screen to adjust what it says; jumpers configure the actual numbers.

I can't seem to find any references to this online, or I just don't know what to search for. Can anyone help me please? Photos available if requested. I imagine this was a standardized thing at some point.

Thanks
Kishkizzle

You would have to track down the instructions for that particular case as they were all different.

I wouldn't worry about it to much though. Those displays were little more than gimmicks which didn't actually do anything. The Turbo button just changed the clock frequency of the CPU to slow it down for some DOS games that wouldn't run correctly at higher speeds. At higher speeds were are talking 80486 speeds at around 100 MHz.

Aw, well, thanks. I was hoping maybe the configuration was universal.

I'll monkey with it through trial & error, ultimately it is not important but I just don't want the screen dead when it's on.

Seems to be a completely generic case, and to make matters worse the panel with the display goes in a 3.5" opening, meaning hundreds of case varieties could have used the same one, but no way to identify it specifically.

I have 2 or 3 of those. The trial and error method is about the only option; but, it is pretty exasperating when you need to move 10-20 jumpers to try for the desired results.

Some will go up to 99 on the display but I've seen a couple that wouldn't go past 25 or 33.

I do recall downloading instructions/jumper settings for one about 6 or 7 years ago...I think it was for a Digital brand workstation.

Maybe this page will help

Thanks, that kind of inspired me. I actually burned out a few segments of the LCD...no idea how, was hooked to +5V...the norm.

So I dug out a second case with display, and the info you provided helped, but not directly.

I was able to determine the letters were switched with letters, for example I had a "2" pin appear 3 times...2 being one of the segments, and there are three digits on the display. Anyway, I got it to successfully display "4" on one digit and "8" on another dependent on switch position.

Thanks, problem solved...just means I'm using a different case. I know its a superficial thing but it adds to the experience lol.

Yeah, it's frustrating trying to configure those. I usually ended up pulling their power wire, figuring no display was better than the wrong display.

Glad you got it sorted out. I'll continue to use the DAVEINCAPS method or stuff an old zip drive in the slot.

In the past, the method I used was to move or remove one strap at a time and see which led segment changed.

This I recorded, replaced the strap and then moved another.

Seem to recall not all straps related to the display.

Also the display had the ability to display different numbers, depending which mode the pc was running. e.g. normal or turbo.

Good Luck - Keep us posted.

Mike, I resolved the problem and configured the screen as I said a couple messages up, but thanks for the info.

In this configuration, there were three digits on the screen. Each digit has 7 segments, meaning the highest number it can display is 999, and the number which lights all of the segments is 888.

Segments are numbered starting at the top, going clockwise around, and then the middle segment is the last one. #1-#7

Each segment number appears three times (as that segment is present three times due to there being three digits) in the jumper block. Each segment number corresponds to a pin, and then each pin has a "t", "n", or "b" setting, being turbo, normal or both, respectively.

This made trial and error much simpler, as while you do not know WHICH of the digits you are adjusting, you do know which segment and which mode. The only trial and error part becomes identifying which of the three matching segment numbers you use, which is easy enough.

Thanks again folks, it worked well. Just a little put out by burning segments on the original case.
