I have a Basic Stamp 2 interpeter using aPIC16C57-HS.

I have it all hooked up with a 20 Mhz crystal. and the 2K EEPROM.
Using my scope it looks like it is running. But I cannot DL anything to it.
I tryed a MAX chip after the NPN/PNP interface want working.

Has anyone used the BS2 interpeter chip before and can help?

Thanks
Alan Nickerson
