|HP-19C with a strange S/N|
Message #1 Posted by Ernst Fueloep on 10 Oct 2011, 11:17 a.m.
I have a HP-19C which has a very strange serial number:
Has anybody seen this?
What is the meaning of it?
The battery contacts are broken. I never saw this before on any HP-19C.
Because of this I am currently unable to verify if this unit works or not.
Here is the serial number close up and rotated 180 degrees for easy reading.
I have never seen such a serial number.
What is it? Is this some kind of prototype?

My guess is that it is a prototype. The 4 zeros are also mentioned in another thread about 71B's:
