 * Verify that the Arduino type you are using is a supported board or that its I/O port definitions match one of the supported boards.  Some other Arduino boards, like the
 Duemilanove, appear to be compatible but have not been tested. Others, like the Micro,
 have different port mappings and definitely will not work without software changes.

+## 28C256 PCB
+
+I built a PCB version for the 28C256 and 28C64 chips because so many burns of these were
+needed for a SAP-1 TTL breadboard computer.  The PCB version with the ZIF socket was much
+easier to work with, compared to prying the chips out of a breadboard without disturbing
+any of the wires.

+## TommyPROM-32
+
+A new PCB is in progress for 32-pin EEPROM and Flash chips.  This design uses a set of
+headers that allow any of the signals to the target chip to be re-routed.  The default
+configuration, with just jumper shunts installed, is wired for the SST39SF0x0 chips.
+
+Many other chips, particularly if they follow JEDEC standards, can be supported be adding
+just a few jumpers.
+
+Chips with few pins can also be supported.  There are power pins in place to support
+28-pin and 24-pin chips with a shunt to the correct VCC pin.
