+====== Taking apart the ReinerSCT nPA RFID Basisreader ======
 The ReinerSCT basis reader is a pretty basic reader for mifare cards and the new german ident-card (ePA or nPA).
-It was sold with german computer-magazine ComputerBild 26/2010 for €3,70 instead of the initial €34,90. It comes with a OWOK rfid card.

 There is a [[http://www.mikrocontroller.net/topic/199865|thread]] on german µC-related forums [[http://www.mikrocontroller.net/|Mikrocontroller.net]] discussing the hackability of this reader as well.

 For handling the USB connection and controlling the RFID transceiver, the reader uses a Cypress PSoC microcontroller.

+**Specs:**
   * 32KB flash
   * 2KB RAM
   * M8C architecture
+    * There is an open-source assembler for this architecture called m8cas, which is part of [[http://m8cutils.sourceforge.net/index.html|m8cutils]]
+    * contains a disassembler as well, m8cdas
+    * There's another disassembler called m8cdis: [[http://www.cypress.com/?app=forum&id=1573&rID=43998|forum post]], [[https://code.google.com/p/m8cdis/|code]]

+    * Yet another assembler, GPLv2 bootloader, USB code [[http://iguanaworks.net/projects/IguanaIR/browser/trunk|here]]
   * internal oscillator with up to 24MHz
   * supports ISSP (in-system serial programming)
-    * it doesn't seem that there are any open-source programmers like for the AVR out there
-    * the Cypress [[http://www.cypress.com/?rID=3412|CY3210 MiniProg1]] seems to support the CY7C64316
+**Notes:**
+  * [[http://m8cutils.sourceforge.net/index.html#progssrc|m8cprogs]], as part of m8cutils, contains schematics for various programmers, <del>but it is unclear yet if it works with the enCoRe V series of PSoCs (to which the CY7C64316 belongs to)</del>
+  * the Cypress [[http://www.cypress.com/?rID=3412|CY3210 MiniProg1]] supports the CY7C64316
+  * I hacked m8cprog to support the chip, by sniffing what the MiniProg1 does, so it is now possible to flash custom code via ISSP without the need for a quite expensive MiniProg1
