Speed comparison Swissmicros / HP

[Bernd Grubert]

Here is another observation that may be related to the speed difference:
When I use the DM-15L (new version with metal domes) I sometimes (~every 10th to 20th) loose a keypress. The lost keypresses usually happens when I type fast. They cannot be reproduced and are not specific to certain keys. When I type slowly everything seems to be ok.

Mr. Steinmann assumed that this could be a hardware problem and sent me a replacement foil with the metal domes, but the problem persists. I have never had this kind of problem with the DM-41L.

It would be interesting to know, whether others have similar problems with the keyboard of the DM-15L. If this is the case the reasons for this may not lie in the hardware, but may be in the software implementation of the keypress detection.
