Hi mackrackit,
Sorry for the late reply, Sunday is 'family' day

(say no more!).
Did my code work on your PicKit1 board?
I did find a couple 684s in the bottom of a drawer. Once the pins were straightned out they worked in the test board. But I had to program them with a PicKit2 The PicKit1 kept giving an error?
I had some errors on Compiling the first program, so had a hunt around looking for Configuration_Fuse info (found this page:http://www.picbasic.co.uk/forum/showthread.php?t=543)
So changed your code to this for the 684:
Code:
DEFINE OSC 4
CMCON0 - from CMON
@DEVICE_INTRC_OSC_NOCLKOUT
@DEVICE_WDT_ON
@DEVICE_MCLRE_OFF
@DEVICE_CP_OFF
The program compiled and ran a treat. What happens is that when a Voltage of 2.5V appears on PORTA.0 (pin13 on the 684) the LED's on D0-D3 light in turn on after the other. If the Voltage drops below 2.5V they turn off. How does that sound.
