If you want only to READ the KI, you need a phoenix compatible device (like dejan's schematic).
If you need to program a new, blank Silvercard with Sim-emu firmware, then you need a PIC-programmer.
this are 2 different modes. The Pic-programmer PROGRAMS AND WRITES on the card, the Phoenix-reader COMMUNICATES WITH THE PROGRAM that is already on the card.
This is also the reason why you will always (except the new pll models) find a crystal on a phoenix device (3.579, 6, 10 Mhz) as this is the part for the communication.
the original sim has already a software (firmware) in it, that for you read the content with a..... phoenix.
The silvercard when new is BLANK. There you would make use of a PIC-programmer to write ONCE ONLY the Sim-emu firmware. When this step is done, you can use a phoenix to communicate with your Sim-emu card.
Hope this will clear some of your questions
