Fixed. I found via email that my issue internal OSC setting problems were because I needed to turn off MCLR, and use the OSCCON setting for 8 Mhz, and it works fine.

OSCCON=%01111000
DEFINE OSC 8

The 18 Parts have LOTS of switches. More difficult a switch than I thought it would be. Working now however.

My settings are:

@ __CONFIG _CONFIG1H, _OSC_INTIO67_1H
@ __CONFIG _CONFIG2H, _WDT_ON_2H & _WDTPS_128_2H
@ __CONFIG _CONFIG3H, _PBADEN_OFF_3H & _MCLRE_OFF_3H
@ __CONFIG _CONFIG4L, _LVP_OFF_4L & 0bfh ;_XINST_OFF_4L

Not sure if I have it all right yet, but at least I am moving forward!

Thanks.

Tom
