I have spoken with Microchip extensively (as well as with several others
experiencing problems) and Mircochip assured me that either (A) I am a
fruitcake, or (B) the ambient room light where I program the JW parts is
what is making the JW's not work and the OTP's work.  They suggested the fix
of covering the parts before each program with a sticker and insist that
there is NO 'bug'.  Anyone else with experience in this matter?  I can make
the OTP's work fine, and can easily set the cal. constant 'on the fly' with
both types; it is just when setting the constant on powerup in the JW's that
causes trouble.

Anyone with similar experiences please e-mail me privately; I have heard
privately from several of you already.  I am trying to gather more data on
the situation.  However, the 12C508's are my favorite device yet.  Keep up
the good work, MCHIP.  And we obviously want 8-pin derivatives with EEPROM,
A/D, and slave I2C.  Hardware PWM would be nice too.

Thanks to all,

Todd Peterson
