The 41C was about three times as fast as the 67/97, but still it does not even come close to a contemporary home computer (with 1 MHz at that time). Execution times of one or more minutes are common for iterative math programs (e.g. matrix inversion).

Thx... feel better now. BTW anyone ever try the DM41L (*want*)? Does that run at HP41 speeds, or closer to V41 speeds? Might put this on my Christmas list just to keep the company a float. Since I've endoctrinated my kids with hp calculators, it would be nice for some company to continue to make an hp clone.

Ahhhh, so it turns out CAPLOCK != TAB. Yes, that is much much better. Thx

Wow.. I just realized that '4.0' uses more program memory than '4'. That really surprised me. I'll need to start looking at how opcodes and constants are stored.

I sent my syllabus / lesson-plan for the computer class I teach, but it's not really in the same realm as Calculus III. Might be interesting to add a section on low-level programming. The RPN 'language' has some similarities to assembler and microcode that would be fun to present.

Got my approval as an Educator *hurray*, so now I'm offically sporting hp35s emulation.

Got the EP file from clicking in the keys at breakfast. Took just over an hour to key in, and just under half and hour to review for errors. Found 2, so I was keying at about a 99% success rate. It runs very well on the sim, I'll report on the physical HW later. In the meantime, can anyone speak to the 35s emulator speed -vs- the actual HW? Where they well aligned?

I'll update the release to 0.2 with the updates as well as some bug-fixes (WIN-BEANS was bugged).
