Seven Segment Calculator

Seven Segment Hex Value Calculator

This utility was written to make it easy to figure out how to display an ASCII character on the Talking Electronics Computer TEC-1.  The TEC 1 has a weird way the segments are connected to the data bus.  To save me heaps of time, I wrote this program to help me work out the Hex Value I should use.

To Use:

Click on the Segments with the mouse to activate them.  The corresponding HEX/Decimal value is shown for the TEC and Standard Segment Setup.  Click on the Button "ASCII", to automatically fill the segments based on an ASCII character.  Use the left and right arrows to change the ASCII value.  Click on "Free" to make a custom segment combination.

Byte Connection to Segments:

From Bit 7 to Bit 0
Standard ->  DP-G-F-E-D-C-B-A
TEC->  D-E-C-DP-B-G-F-A
