Hello PICante,
The 628A has analog comparator inputs, so unless you are using them turn them off with
CMCON = 7
then read the post on config fuses
try:

@ DEVICE pic16F628A, HS_OSC ' Change HS to XT for 4mhz

@ DEVICE pic16F628A, WDT_ON
' Watchdog Timer

@ DEVICE pic16F628A, PWRT_ON
' Power-On Timer

@ DEVICE pic16F628A, MCLR_ON 
' Master Clear Options (Internal)

@ DEVICE pic16F628A, BOD_OFF
' Brown-Out Detect

@ DEVICE pic16F628A, LVP_OFF
' Low-Voltage Programming

@ DEVICE pic16F628A, CPD_OFF
' Data Memory Code Protect
' Set to CPD_OFF for Development Copy
' Set to CPD_ON for Release Copy

@ DEVICE pic16F628A, PROTECT_OFF

DEFINE OSC 20 ' for 20 mhz, change to fit your OSC speed

that code should setup your configs if using the default compiler, MAPSM uses different configs.
