I acquired a new keyboard yesterday from a thrift shop. It's an old IBM rubber dome keyboard from what what I can tell. It is large and built like a model M but doesn't have the click in they keys. On the back of the keyboard is a 3 way toggle switch which changes the volume on the built in speaker. The model number is 6247440. I tried using it on all my computers but had no luck. It would not register, just make a loud humming sound. Does anybody out there have any info on this keyboard? Thanks.

Great find ! ^^ are rubber dome model Ms popular in here? ^^
-
Here are a few more stats on this keyboard: Manufacture date September 4, 1989. Made in Japan.
-
Barney, how much did you pay for that ?
-
Hmm, Japan? Mind putting up some pictures of the thing?
-
Here are several pictures of this keyboard. Let me know what you can about it.

Those keys are awesome. Wish I could make use of them on some of my boards, but they don't fit the BS keyboards, if I recall correctly.
-
I paid $10 for it.

The port on the back is a ps/2 port. I was able to plug a cable into it and connected it to my modern computer. It made a buzzing sound out of its speaker but did not work. I tried connecting it into two older systems (486/DOS and Win 95/K6-2) but the computer didn't boot correctly. The video would not work with this keyboard installed.

I think your right. It did make a buzzing sound, but I don't think it was harmful in any way. My computers still work fine and Im sure the keyboard does also.
-
Cool...next step would be inside :)
I'll tell you right now, IF that is indeed for the 5086, it is not PS/2 or anything like it and further connection attempts could fail in spectacular ways...those connect via, if I am to understand it correctly, a D-sub on the other end of the cable and are super-proprietary. (don't quote me on this - may or may not be true - as I said, I'm sitting on info that needs to be confirmed)
Out of curiosity, what info are you sitting on? Is my keyboard worth $225,000....I wish. Do you know somthing fascinating about this keyboard that I don't. Let me know, I'm dying to know.

Well, for a while there you had me thinking I had a rare as hell keyboard....only a total of 8 ever built. Oh well.
-
You could always buy it from him kishy. I'm sure we'd all see internal pics then.
-
I can get you some internal pics. I already opened it once but It was a pain. Everything is mounted to the top of the case instead of the bottom. I'll get some together and post them tomorrow.
-
I figured what the hell, why not do it now. Here is a pic of the inside. I didn't remove the metal plate from the casing but you can see a good shot of the circuit board inside.
