First Stage, Assemble and Test the CPLD

Start off with a blank Tiny030 pc board:

The first stage is to assemble and test the CPLD by driving a few LEDs.  The CPLD is Altera EPM7128SLC84 hosted in a through-hole 84-pin PLCC socket.

Add the 68681 40-pin socket because jumpers are needed to connect CPLD output to 7-segment display.  Populate the EPM7128SLC84 as shown and insert 4 jumpers from the 68681 socket as follow:

• pin 12 to pin 35
• pin 13 to pin 37
• pin 14 to pin 9
• pin 15 to pin 21

This connect 4 currently unused CPLD outputs to 4 of the 7-segment display.  Also populate the oscillator.  Here is the Altera CPLD programming file.
