It makes me remember about a very beautiful sentence I read on a French forum which said "Knowledge grows up provided it is shared". ("la Connaissance s'accroit quand on la partage") So, here's a few more about me : Already as a kid I dismantled everything I grabbed, I've always wanted to know what goes on under the hood. To me, calculators and computers are especially amazing since they're the only machines in which we can -literally- embed some part of of our mental processes. Among my heroes are Isaac Newton, Charles Babbage, Nikola Tesla, Alan Turing, and so on... as a student, days after being given that broken HP21 by a friend, I discovered in the classroom the HP9100 that my IT teacher had teared into pieces because it stopped working. I was astonished : a calculator made up of discrete components ! What a wonder. To the others it was just junk, those were the microprocessor days. I was able to get some boards (ROM, microcode, flip-flops...) which I preciously keep, and I'm still dreaming of a complete machine. I've read the Osborne patents again and again, and so many other patents. All of that definitely triggered what I'm still doing : trying to preserve whatever I can. That's why HP calculators were the first I collected, soon to be joined by TI, Casio, Sharp, Odhner, Friden... and now slide rules :-) My favorite HP is -err, not so easy ! Is it the 9810, or the 67 -and what about the 11C, and the 25 ? They're all special :-) as are the other brands. ...and, speaking of what's going on under the hood : "to better understand it, build it". The 6502 RPN homemade calculator I'm working on is based on Charles R. Bond floating-point library (first tribute) and the hardware I built with great help from Garth Wilson 6502 site (second tribute). The 80's technology is attractive because you can control each single bit. -please forgive me, I'm away from HP. Some of my friends say I'm nuts, now you understand why. I'd rather say I'm assembly-twisted :-) Marc |
