701 Emulator, Version 1.03

A bunch of tweaks, and one larger change: Timing is now much more realistic, reduced to 701 speeds. I/O timing is an approximation, using a simpler model than the 701 itself. For example, the line printer prints at close to 150 lines-per-minute, as it should. The previous version printed much too fast. Also, there are some examples that you can copy with a command on the File menu.
