Upper case

The workhorse printing device of the 1960s/early 70s, the 10 character-per-second Model 33 Teletype (trademark of the Teletype Corporation of Skokie, IL), printed only uppercase. If you sent it an ASCII character code for a lowercase letter, it simply printed the corresponding uppercase character. It printed on 8.5" wide rolled paper, usually "canary yellow."

In the minicomputer world, file name extensions were 3 characters long (uppercase of course), since we figured out a way to cram 3 characters into one 16-bit word (2 bytes) by limiting the character set to A-Z, 0-9, $, -, and underscore. The 3-character convention lives on to this day.

Lower case became popular in the mid-1970s with the invention of the 5x7 dot-matrix printer and, later, the daisy-wheel printer.

Here's a couple websites I recently found which others may be interested in.

http://seattleavionics.com/products.shtml

Voyager Free Flight, free version, similar to AOPA's Flight Planner but with DUAT weather, terrain, etc. It's web based and can be customized. It's a huge program, a real memory hog and needs a fast internet connection. My three year old laptop barely handles it. Has Alaska also. Interesting to play with as planning tool for this VFR only, low time, low experience pilot.

This has current sectionals including Alaska.

I just found these this week. I'd been looking for a sectional site so I could look into planning a route to central Oregon to visit my only sibling without buying the necessary sectionals.

Ah, now THEY have remembered that there are 50 states not 48 (see my earlier post) :wink:
