It always seems cheaper half the world away. I found a long time ago I could get cheaper dive equipment from Fla. even though it was made up by Chicago (Dacor). Same with flying. Our little regional airport CIRA (BMI) has flights to FL, CA, Mexico for $99 to $149. BUT try to fly from here to Oklahoma City or Kansas City and its $400 !!!!

...and, I probably contributed to this momentary "de-railing" when I jumped on the EEPROM issue (I'm an EE ...

Then you should check this link out.

Me too, BTW, with a dash of Comp Sci thrown in on the side.

I gave up on the 'stripped-down' idea and just ordered a complete Davis Vantage Pro2 with 24-hr Fan and WeatherLink Package from Rob at Rainman·Weather.

The wife wanted to know *why* I was buying something from Florida that was made just next-door in California? My tongue-in-cheek answer: 'cuz YOU guys (here) recommended him (I support those who support us)!

Thanks everyone!

I'm sure you'll love it.  Good luck!  Smile

...nice write up. Laughed my ass off at 'Mad Scientist Labs.'

...now, it's your turn, Google: "TRS-80 Assembly Language Made Simple"

You wrote that?  I'm impressed!  First computer game I ever played was "Taipan!" on my teacher's Model I.

Anybody who programs should take a crack at assembly.  Nothing like programming on bare metal.  I did some 6502 and PDP-11 way back when, with some x86 not that long ago (video game emulation is another interest of mine).  Might have to learn AVR assembly for this Davis stuff before too long as well.

To appreciate symbolic assemblers, you should start with absolute machine language.  [IBM 650, 1957]

The "first" microcomputer "kits" (MITS, IMSAI, Pertec, Scelbi) were all machine-programmed in 'native' binary code via front-panel toggle switches; UP for "1" and DOWN for "O", as were the DEC PDP-series (pink & black), although "boot-strap" loading through RS-232 Teletype paper-tape was popular.


Of course, you had to first toggle in the codes to cause the paper-tape reader to work.

(On the IBM 650, it was toggle in the codes to cause the punched-card reader to run).

Today, that's called the BIOS.
