Early (earliest?) HP-41C find.

[Diego Diaz]

Yes, my earliest production unit is also a three transistor with CPU board H-1914.

It comes into an HP-41C s/n 1941Axxxxx and D, D, E, OS version.

Tall keys, golden ball AC contacs and *shiny* faceplate (instead of the matte one) with grey frame line (instead of silver).

   

Hope you can see in the picture.

Cheers!

Diego.
