New digital microscope and the 19C

[Geoff Quickfall]

As usual at HP they would create something for many products.

The third photo shows the ability to show a colon. Maybe some of the uses for this display in other machines that were not created was for a time display such as the HP 01.

Hi Bruce, will get to a meeting in the new year. Say hi to everyone for me.

Cheers, Geoff

An aside, the HP 34C display (not good resolution as the LED protective red lens is very thick). I will be photo-documenting the LED displays for the book.

You can see hp logos here but none are wire bonded and I don’t think, even if they were there would be a use. Their position would only be good for a colon and the lower one is not co-commitment to the decimal.

Also the decimal is two small rectangular LEDs.
