Good time is back

I bought my HP34C on middle 1981, when I began technical high school, works good for the next 10+ years, went to Engineering College, after then used in my job. R.I.P. But now it is back… 😃

Awesome app

It is obvious this is a sophisticated, mature app. RPN-34 CE has surpassed my highest expectations. Amazing!

Faithful Reproduction …

… of the calculator that got me through tech school, a few years of Uni, and then beyond. If you can’t do it with this math powerhouse (now enhanced in all sorts of ways by CuVee), then you just haven’t the patience to learn.

Terrific !

The HP-34C was the Cadillac of the Spice series. It’s built in functions were even more powerful than the HP-67, but with one glaring drawback. The original had no way to save programs. RPN-34 CE fixes that with an easy way to save & retrieve programs to several different media, even email. What’s more programs can be up to 999 steps long, with no loss of storage registers. Lots of wonderful extras!

Another win for Cuvée Software

This simulator is just too great! I have an HP-34C from my undergrad days in the early 80s. I've used fairly regularly until the last 10 years or so. The switches have become noisy so I've archived it just so that it stays fully functional going forward. I couldn't be more thrilled to now have it in my iPhone !!!! RPN-34C is well done indeed.

Cuvée Software has created fantastic simulators of some of HP's best calculators with TONS of enhancements. I absolutely love the work. It's fun to take trips down memory lane but it didn't take long to get addicted to enhanced features and speed of RPN-34CE :) I use the RPN-67/97 simulators to solve very real problems. I'm now including the RPN-34C for that purpose too. I don't normally sing praises like this but I'd be dishonest if I didn't in this case! Cuvée products are truly a cut above the norm (maybe even >2sigma ;)
