HP 1980B oscilloscope Measurement System Analog/Digital 100MHz

I think it was released in 1982-83, and i think my model is about about 85
Last calibrate 1993 sticker on mine, so it was maybe only used for 10 years,
Tons of cool info online about this model, just google a little bit, manuals and schematics and full how to use and all.
I found a few problems with mine, super happy i did a deep going visual before power up.
I found a weird sw bug, but I think it is how they just are ? really ?
this is my number 63 Hewlett Packard video, go have a look..
