Hehe - sorry about the thread hijack!
Bill - oh my - log tables - of course all I had at school. I meant to also refer to that other ''miracle'' the analog slide rule - I was thrilled when I was given a small 6" one by a professor and used it for ages. I recall too its smell - that ''ping-pong'' ball celluloid aroma! Ahhhh the nostalgis.
I built a Heathkit audio amp and did build a small programable calc' - in UK and that had the ''Sinclair'' name - was a lotta fun.
RPN - heck - had all but forgotten about that. My TI calc - I guess without checking maybe the TI-50 - was also somewhat rendered obsolete by cost of batt replacement tho I did save one new pack purchase by making a new pack with 3 AA size NiCads and getting it in tho the silly spring contacts often played up and needed cleaned.
Back to regular programing
