Are the oscillator jumpers set properly on the Lab X2?

[No Oscillator jumpers 4 MH Crystal only]

Is the PIC installed properly?
[Notch in the wright direction]
[I hope so, I puled it up and pressed it down]
I hope so, I puled it up and pressed it down
it reads the chip and erases.
Only one jumper for 5k Pot

I hope so, I puled it up and pressed it down
it reads the chip and erases.

Maybe voltmeter on Lab X2 transformer jack to make sure it's working?

Are there other chips installed on Lab X2 that might interfere?

My power supply is from a regulated filtered 3A 12v Omron
LAB_x hase a 7805 regulator
chip has 5 v power
Jack is working, led is on !
Are there other chips installed on Lab X2 that might interfere?
No no other chips are installed.


The only reason I switch to the 16F877 was because I have one
and I installed it in the meLab LAB-x2 board

I want to make sure everything is from meLab and hopefully works
together including there program samples.

U2 programer, cable, LAB-X2 board , recommended PIC chip,
and there sample software (blink3x2) .
