hi eric,

"5) You need to buy a programmer. If all you need is to 'rescue' a few chips with the reset vector or status byte blown, your local, friendly Philips FAE will help you I'm sure"

I have managed to, probably mess up my boot vector byte, or maybe it the status byte. What a strange coincidence :-( And i was stupid enough not to use the notouch procedure!! So I can't seem to get my chip to boot in the ISP mode again... I do have access to a parallel programmer. Now what exactly should i do to get the chip back to the "ISP" mode?
