You gotta love a language in which a statement like: >> The definition of ? is >> : ? @ . ; makes complete sense :). Actually, all of you RPN fanatics would love FORTH, as it is essentially RPN based. Add some labels and control structures, and whalla! You have a programming language! 2 3 6 * + . Does just what you expect: 2, 3, and 6 get pushed on the stack, * multiples 3 and 6 and replaces them with 18, and + adds 2 and 18 and replaces them with 20. The period (.) writes the result to the terminal and removes it from the stack. If you do something often, you can add a new operation to the system with a colon definition: : CUBE DUP DUP * * ; and now you can write: 3 CUBE . and it will pring 27! Every modern RPN calculator should come with a built in FORTH :). _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

his Reflector now you want it to be perfect? It was supposed to be a bumper sticker not an app ;) : Honk 7 EMIT ; : Cheers Forth Love? IF 10 0 DO Honk LOOP THEN ; Funny thing about Forth is it is very close to assembly language in speed but writes like a high level language. Wonderful for bit banging and writing AI code in the same robot. I used it for a number of robotic projects in grad school. The very first OO language too. Methods and data were in the same bag way back in 1980 when I started learning it. Great for embedded stuff too. Fast prototyping and great results. You can actually use the prototype unlike a certain Visual language I've used. Kevin.

I'm holding on to my HP15C which I bought in college in 1987, still have the receipt. My boss here was looking for a good RPN calculator and figured he might find that one on eBay cheap. WRONG! Turns out that very good examples of it, complete with manual and case are about $300 to $400. Even one with a broken LCD display was still over $100, more than I paid for it new. Not sure when (or why) HP discontinued it. They still make the financial version (HP12C) which is the same form factor, just different button assignments.
I also have an HP48G+ which is still RPN. Not sure if it is still made or not. I got the '48 about 5 years ago. Some of the '48s have expandable memory slots, however, mine has 128k fixed RAM. I've seen where people have programmed it to use its IR port as a remote control! Hmm, wonder if the HP48 can be used to control the K2?

Hi
I have and use regularly a HP-25 that is about 30 years old. The NiCad batteries failed many years ago so I mounted a 2.5 volt regulator made with a LM117 inside the battery box and power it with a wall wart. Once you learn RPN nothing else seems as easy. I also have a HP-28C and it programs with a sub-set of FORTH. If HP has dropped all of the RPN calculators from the line, one of the several aps for the palm may be the only place you can find it. I also have around here somewhere a little single board computer that is based on a 6809 with FORTH built in in firmware Don Brown KD5NDB PS I have a Helix computer out in the garage now. It was the final generation of the SWTPC 6809 SS 50 buss computer. It probably still works although I have not tried to boot it in 10 years. It's OS was Flex, a much better design than CP/M in my opinion. I still make my living writing 6808 assembly language for small controllers.

HP now makes the HP33s (~$45), which is a slightly enhanced 32sii & does
RPN or algebraic. Looks like marketing was at work, though, since they put the buttons in a strange V pattern. I've also read that the decimal point is tough to see. And for matrices, differential eqns, etc., you can now upgrade to a 49g+. Great functionality, but I think HP has lost a bit in the quality department. The newer calcs just don't have that solid feel of the older brown ones. (But I still buy them!)

Jeeez, all you guys are just kids! I cut my teeth on an IBM 650 as a
Stanford undergrad. OS??? Listen, we entered the boot program through the front panel "switch register". The 650 occupied three large cabinets in a heavily a/c'd room (it was GREAT in the summer!). 2000 10 digit "words", plus sign, of drum memory with an incredible 96 ms add time! Languages? Well there was SOAP, IT and the state-of-the-art FORTRANSIT, which, of course was built on top of IT....a very crude early attempt at FORTRAN! SOAP was an assembler that placed instructions on the drum in an optimum fashion to overcome the drum latency. >From the 650 Stanford "upgraded" to a Buroughs 220 which had 10k decimal words of CORE memory! Also tape drives! BALGOL (Burough's dialect of ALGOL) was the language of choice though assembler was still heavily used for those of us who needed real efficiency. Dick Hamming was at Stanford at this time and chatting with him while waiting for output taught me more math and numerical techniques than I had ever learned in the classroom. We also had a (one of 3 built) IBM 797 which was essentially a 650 with core memory and was plug board programmed with a 402 printer plug board! Of course we went through the 7090, B5000 and 360 series. At that point I decided that my interest in computing/radio/electronics got me into real-time computing with HP-2100 series mini computers. I worked for the Stanford Radio Science Lab (and later SRI Remote Measurements Lab) developing control , data acq and processing/display systems for SRI's experimental/test bed OTH radar using single board computers from Ziatech. Man was that ever off topic! I'll mention something "on topic". I saw a new Elecraft thing at the DX Convention in Visalia. Wow!!

I just got back in town from a Long Weekend at the Visalia DX convention. Looks
like we've had a lot of emails on the list this weekend! (It always seems to happen when I'm off line..) In any case, lets end this non-K1/K2/T1 etc OT thread for now to relieve the email pressure on others ;-) Please remember before posting lots of off topic comments to the list that we have close to 1900 subscribers now, so the number of daily emails can explode in volume when everyone hits the return key a little too quickly or frequently :-) Also, please edit all copied text from previous posts down to a couple of sentences when replying to postings. This makes the list archives and daily digest much easier to read. 73, Eric WA6HHQ List moderator ---------------- _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Jeeez, Doug, you're just a kid! I was a field engineer installing huge
vacuum tube analog computers (EAI 231R among others) all over the East Coast and southern Canada. Customers included NASA, Pratt & Whitney, Perkin-Elmer and just every Ivy League and Bush League university in that region. Digital stuff was sort of interesting in a primitive way. We interfaced them to analog computers to do the mundane number-crunching and flow control chores while a couple of analog computers accomplished the heavy lifting. I notice there is renewed interest in analog computing. Even with all the gigawhiz CPU's out there, it is hard to beat them for differential equations. They are also more intuitive to program for an engineer. BTW, dug up a 650 simulator you might try. I haven't played with it yet, but it might be interesting. http://infinitefish.com/650/ Eric KE6US -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Douglas Westover Sent: Monday, April 18, 2005 11:34 AM To: Robert McGwier; Elecraft Mail; Kevin Rock Subject: Re: [Elecraft] Now that we know Jeeez, all you guys are just kids!

Dick Hamming was at Stanford at this time and chatting with him while waiting for output taught me more math and numerical techniques than I had ever learned in the classroom. We also had a (one of 3 built) IBM 797 which was essentially a 650 with core memory and was plug board programmed with a 402 printer plug board! Of course we went through the 7090, B5000 and 360 series. At that point I decided that my interest in computing/radio/electronics got me into real-time computing with HP-2100 series mini computers. I worked for the Stanford Radio Science Lab (and later SRI Remote Measurements Lab) developing control , data acq and processing/display systems for SRI's experimental/test bed OTH radar using single board computers from Ziatech. Man was that ever off topic! I'll mention something "on topic". I saw a new Elecraft thing at the DX Convention in Visalia. Wow!!
