That's a fascinating story! I'm assuming those 'bugs' were also present on the HP-80, HP-70 and HP-22 then. So would be really interesting to see what kind of results people get from these devices and after.

Unfortunately the HP-80 failed at all the "solve for i" tests, so maybe we won't pick it up. There was a second part to problem 1 where we do a relatively easy solve for i, so maybe I'll integrate that into the answers.

Also, this is far cry from the HP more recently (referring to their practices around printer ink subscriptions).

EDIT: Also, strange to tell a consultant they don't need to know what a part of the calculator does, when you're asking them to test it!
