PORTA Logic - Be the processor

Do I get a prize or something?

Hmmm, I guess being qualified to play with your own "PORT" isn't worth much when you're married.

144 That's "Gross".
Actually, I don't think I ever got higher than that either.
And I knew the questions ...

I can see a lot of really nifty tutorials with your Flash gadgets. Very cool stuff.

This reminds me of the Microchip eLearning Flash-based training modules. Nice work
DT. P.S. I had a 145 just before this one, but thought I could beat it. Didn't happen...;o}

Sounds interesting. I'd like to see those.
Can't seem to find them though. Google let me down?

Uh huh, suuure you did ...
My next one will impose a 10pt handicap for anyone with Bruce in their username.
not

Here's the link to Microchips flash training modules; http://techtrain.microchip.com/x14/

Those are pretty interesting.
Gives me a few ideas too.

Your game was fun, I got a 109 (better hit the books again)

I have been migrating an application from a 16F887 to a 18F4420. After some debug (few hardware issues - oops!) the two output ports are doing great (B & D). Thanks to you Darrel my Timer 01 interupt is clicking away. I was able to change the config1h register to use the 4x PLL oscillator. But I am having trouble getting my input ports (A & E ) to function (very ashamed )
Oddly enough, there is one bit of the A port that works (bit 4). The rest of inputs on port A and E ignore me. Hardware check of pins show normal (pulled to Vdd via resistor with contact closure dragging them to Vss when applied)

Below is the I/O setup from my program:
================================================== ======
' ~~~~~~~~~~~~~~~~~~~ Define A I/O Port and Define Analog I/O ~~~~~~~~~~~~~~~~~~~
PORTA = %00000000 ' clearing bits as recommended in data sheet
ADCON0 = %00000000 ' turn off all A/D
ADCON1 = %00000111 ' turn off all A/D I/O points - make digital
TRISA = %00111111 ' bits 0-5 declared as inputs

' ~~~~~~~~~~~~~~~~~~~ Define B I/O Port ~~~~~~~~~~~~~~~~~~~
TRISB = %00000000 ' bits 0 declared as output


' ~~~~~~~~~~~~~~~~~~~ Define C I/O Port ~~~~~~~~~~~~~~~~~~~
PORTC = %00000000 ' clearing bits as recommended in data sheet
TRISC = %11110000 ' bits 4,5,6,7 defined as inputs
; LATC = %00000000 ' bits 0,1,2,3 declared as output

' ~~~~~~~~~~~~~~~~~~~ Define D I/O Port ~~~~~~~~~~~~~~~~~~~
TRISD = %00000000 ' bits 0-7 declared as output
; LATD = %00000000

' ~~~~~~~~~~~~~~~~~~~ Define E I/O Port ~~~~~~~~~~~~~~~~~~~
PORTE = %00000000 ' clearing bits as recommended in data sheet
TRISE = %00000111 ' bits 0,1,2 declared as inputs
' bits 3-7 declared as output
' to prototype Application inputs
================================================== ======

Does this look as you would expect? Got any other areas you would recommend I check - I think I am close to being able to recite the 18FXX2 data sheet, but it doesn't mean I might be overlooking something.
