Nice finding in a drawer
Today I have found this in a drawer at my work:
[img][/img] [img][/img] It is dated 1968. Not sure if it fits in the "HP handheld calculator" category :-) I'm not sure about its intended use. Apparently it can calculate the rise time measured by an scope as a function of the probe parameters, but the resistance range seems low (up to 10 kOhm) to me (perhaps that was the norm in 1968, but I cannot say). The back can compute the signal loss in the probe. |
