[QUOTE="2old4this, post: 7302, member: 174998"] What are "C-cards" and "Q-cards"? Where have you come across those names? Your green pcm 16c84 card is no good for digital sicne the "c" version of that chip needs to be an "f" version for digital (more memory). And a goldwafer is a goldwafer is a goldwafer. If the thing is described as a goldwafer then it means it has a 16F84(A) PIC and a 24(L)C16 eeprom. Regardless of what the lines and circuits look like. And a goldwafer is the most commonly used for digital systems. There have been various types of card produced in plain white plastic. You need to find out the specification of the internal chipset. Some are NOT suitable for digital reception (eg the single-pic cards, or the dual-pic master/slave arrangements used for some D2MAC) Almost all programming utilities cause an implcit erase before writing to the card. But if you're in doubt, do it as a separate step (it's only one click more with the mouse....) 2old [/QUOTE]
