Like the HP-35 and HP-41 and other HP there are versions in the HP-94E.
Pictured are HP-94s with 2 types of serial number labeling.
1st picture is an HP-94E with a stamped serial number
2nd picture is an HP-94E with a printed serial number on a white background
Which type is more common? I think the stamped serial number is more common but am not sure. What type serial numbers do others have?
Are there other HP-94 variations besides the D,E and F series?
