3421A CAL RAM

[BobVA]

I managed to get the cal information out of my 3468A, but only after this hilarious goose chase:

- Dig out 82160A HP-IL interface, only to realize HP-41 has packed up.
- Fix HP-41, connect to 3468A then realize that 41 only accepts 24 characters in an HPIL response.
- Dig out PILBox and set that up on bench computer. Side trip on failed quest looking for second HP-IL cable. Bodge something.
- Realize ILCtrl can't issue a "Talk" command, so even though I can send the "B2" command, there's no way to read it.
- Consider learning C++ or VB so I can modify it to do this, but then realize I'm not smart enough.
- Re-read 82160A manual and realize that the entire string *can* be read by the HP-41 using multiple "INA" commands. Bang head on bench.
- Connect printer to HP-41 and use 5 line program to read and print cal data.

Done! :-)

(Still not sure how I'd write it back if I had to, but perhaps the B3 command followed by the data would work from ILCtrl, since a response isn't needed.)
