Sure, any good engineer loves a challenge :-)

I my early professional career (mid 70's) I can remember working for days to get one more byte of code space in an intelligent (?) terminal that had 4k of memory, 2k of which was dedicated to the display.  We even did unthinkable things like self-modifying code to save space (hangs head in shame ...) ...

Anyone else ever work with Incoterm terminals?  You might remember the rather large blue, metal cased terminals that United Airlines ticket agents once used.  They we Incoterm 1020's I believe (boy, that's reaching way back in the databanks!).  If the agent mad you mad all you had to do was reach down and press the little red "boot" button and she was out of commission for quite awhile.

Wow, amazing what you can find with Google.  Here's a page that talks about it and United Airlines: http://www.vintagecomputing.com/index.php/archives/33

Back to the world of today:  At the moment I'm running more into a RAM limit than a flash limit on the ATMega32A.  I expect to add significant functionality down the road which will eventually consume more flash ... and I learned my lesson ... go big! :-)
 
Cheers,
