AWWWW!!!  Wait a minute!!!  Are you guys asking what power supply I am using???  I was using a multi-voltage (3V to 9V) Archer power supply from Radio Shack.  You and Parallax advise me to try the power supply Parallax sells for the Tech Board.  Its ratings are 7.5 volts at 1 amp.  The Archer power supply I am using cranks out only 300mA - one third of what is recommended.  That should be the culprit!  Radio Shack probably is still selling wall adapters of 3 to 12 VDC, even at 1 amp.  The 7.5V, 1 amp power supply Parallax sells may also be selling at Radio Shack, too!  I'll personally find out if that is the problem.  By the way, the breadboard I was using to test the chip is 12VDC with a 7805 regulator that regulates the voltage to 5 VDC at 1A.  When I try out the power supply with the specifications Parallax recommends and this solves the whole thing, I'll let you know.

Oh... one more thing... the $500 I mentioned is planned for purchasing a Xeltek 280U Universal Programmer.  I want to program more than just SX chips and this universal programmer (and an alterlative called 'Leaper') may support SX18 and SX28 Chips.  When I resolve the issues, one of the experiments I would like to work on is to take my SX/B programs and convert them to HEX formats for the universal programmers like the Xeltek.

Thank you for your support.  I appreciate your replies!
