Title: What exactly is this in the world of IBM keyboards......?
Post by: Elrick on Sun, 19 August 2012, 20:34:41
This is a first for me, I have never seen this type of Model M/F type of keyboard before.

http://www.ebay.com/itm/IBM-KEYBOARD-104-KEY-DATA-ENTRY-P-N-09F4231-/110784583539?pt=PCA_Mice_Trackballs&hash=item19cb469773

It looks like some kind of rubber membrane but the key samples shown by the seller look very different to what I have seen.  Can anyone shine any light as to what exact key switches it uses, because it is an old IBM afterall.

Rubber dome; I have one.

Same interface as other terminal keyboards, easily adapted with Soarer's converter.

To sort of expand on the switching mechanism: there are two metal plates similar to a Model F, with individual slider mechanisms mounted to the top plate, and individual domes per key with a membrane below to pick up the keystrokes. It doesn't feel especially great.

Oh thanks for that.  So IBM did make some rubbish then.

It's a shame because the keys themselves looked complicated and fooled me into thinking it was some kind of "SPECIAL" keyboard perhaps with some unique features similar to an early version of a Topre like switch.  But it's no way near that switch.

It's nice to see we are all mature here... not.  ^-^

Fortunately, it was made by Honeywell. :D

It's supposed to be pretty good for a RD.
Note IBM also made the same layout as a model F. The "space unsaver" or 1387033. I have always wanted one.

To up the maturity ante here, Cumming is indeed a very unfortunate name.

Worse, Forsyth County itself (a northern ex-urb of Atlanta) was, until very recently, one of the most blatantly racist counties in the country, hosting Ku Klux Klan parades on main street into the early 1990s, if I remember correctly.

That abruptly collapsed in the late-1990s housing boom, and now, at least, the southern third of the county is now hardly distinguishable from other Atlanta suburban areas.

It will crush your heart, then, to know that I know of a parts reseller that scrapped possibly two of them.

I was a little ticked off.

Broke my heart  :(
