-Microcontrollers known to work with the HV Rescue Shield
+Microcontrollers known to work with the [[http://mightyohm.com/avr_rescue|HV Rescue Shield]] and [[http://mightyohm.com/hvrescue2|HV Rescue Shield 2]]
-Hardware versions < 2.0:
+This list is in progress and by no means complete.  Most devices that are pin-compatible with the ones shown here will work with no modification to the Rescue Shield software or hardware.
+If you have good results with a device that is not listed, please consider adding it.
+Hardware versions < 2.0 (the original version of the shield):
   * ATmega48/88/168
-  * ATmega328P
+  * ATmega48P/88P/168P/328P (only 328P has been tested)
-  * ATtiny2313
+  * ATmega48PA/88PA/168PA (should work, but have not been tested)
+  * ATtiny2313
-Hardware versions >= 2.0
+Hardware versions >= 2.0 (the HV Rescue Shield 2, with 3 IC sockets):
   * All microcontrollers shown above for the original hardware
   * ATtiny13A
-  * ATtiny85
+  * ATtiny25/45/85
+  * most 8-pin ATtiny microcontrollers should be supported, since they share the same HVSP protocol
+  * if you have tested a part not listed here, please consider adding it to the list!
+Note: Not all ATtiny parts have an EFUSE.  If you try to read the EFUSE on a device that doesn't have one shown in the datasheet, it will most likely return 0xFF, and attempts to change it will not work (but could have unexpected results).
