When I count HP-42S functions I get 252 (and that's not including [FIND], [MIN], and [MAX]). Dex Smith

I thoroughly enjoyed your comparison of HP calculators - it was a lot of work! > BINARY > The 42S actually feels the best for interactive bit operations, but > its wordsize is fixed at 36 bits. We chose 36 bits because it is divisible by both 3 and 4. Thus it works out nicely for hex as well as octal. We couldn't afford to implement 64-bit binary operations/display (ROM constraints) and felt 36 bits was a reasonable compromise. > COMPLEX > The 42S is the best of the pack, however, as it is the first to display > complex numbers in polar as well as rectangular coordinates. ... > The 42S particularly is a great complex arithmetic machine ... > MATRIX > The 42S is the winner again for incorporating matricies smoothly with > other types of numbers and overloading the operators ...

Not bad for *half* the ROM !!!!!!! Pam "I couldn't resist - I worked on the 42" Raby pam@hp-pcd

We've seen two follow-ups with the Subject: line as above, dated 9 and 13 Ma, but have NEVER seen the basic posting with the actual HP calculator comparison! We feel very deprived! Would whoever posted that originally please re-post it, or mail a copy to "info-micro@wsmr-simtel20.army.mil" so it gets on the info-micro mailing list on the ARPA/MILNET side, please!?! Thanks much!
