I got an e-mail recently from someone offering me an Esco 31 survey
calculator. I'd never heard of one but I decided to take a chance and
bought it sight unseen. It came today. The seller forgot to mention that
it said Tektronix on the back! Yeap, it's a rebadged Tektronix 31! Does
anyone have some instructions for one? Does anyone know where to find
tapes for these?
