 ## Introduction
 
-The DuPAL board is a simple circuit that mounts an AVR MCU (A classic ATmega328P of Arduino fame), three 74HC595 SIPO registers, one 74HCT166 PISO register, a MAX232 to adapt the serial port to RS232, a linear voltage regulator and a bunch of other passive components.
+The DuPAL boards are tools meant to help in dumping/reversing the content of some PLDs and memories.
 
-This board was designed and built to help myself bruteforce PAL devices. It has the hardware facilities necessary to scan all the inputs of the PAL, to check whether an output is high, low or hi-z and to report back the status to the host.
+The original DuPAL revision 2, currently supported by most tools, but limited in support to PAL devices (with the exclusion of PAL22) can be found [here](boards/DuPal_DIP).
 
-Details on how the features are implemented can be found on the Firmware's repository.

-## Software
-
-### Bootloader
-
-This board uses the [Optiboot Bootloader](https://github.com/Optiboot/optiboot), currently at version 8.0, built for an **ATMega328** running at 20Mhz, and with a baudrate of 57600bps.
-
-The command line to build the bootloader is
-
-```shell
-make atmega328 AVR_FREQ=20000000L LED_START_FLASHES=8 BAUD_RATE=57600
-```
-
-See [Compiling Optiboot](https://github.com/Optiboot/optiboot/wiki/CompilingOptiboot) for details.
-
-The resulting bootloader can then be loaded via the ISP header. For example, by using `avrdude` and an **AVR Dragon** programmer:
-
-```shell
-avrdude  -c dragon_isp -P usb \
-  -p atmega328p -e -u -U efuse:w:0xFD:m -U hfuse:w:0xDE:m \
-  -U lfuse:w:0xFF:m -U flash:w:optiboot_atmega328.hex
-```
-
-### Firmware
-
-Details on the firmware can be found on the **DuPAL_Firmware** repository.
-
-## Hardware
-
-The board was designed with [KiCad](https://kicad.org/) EDA.
-
-In its current form, the board is a pretty simple build, using exclusively through-hole components.
-
-### Powering the board
-
-The board can be powered with a DC supply voltage between 7.5V and 9V, 12V is possible but the regulator starts to get hot.
-
-The power connector has a positive tip, and is protected against reverse voltage by a 1N4001 diode.
-

-## TODO
-
-* New version with additional 74HCT166 to support PAL20L10 chips...
+The [DuPAL V3](boards/DuPal_DIP), AKA "dupico", has more potential and will eventually support a much larger number of devices, but most of the tools have not yet been ported to it. Adapter pods for the dupico can be found [here](boards/dupico_pods).

+## Introduction
+
+The DuPAL V3, AKA "dupico" board is a simple circuit that mounts a Raspberry Pico (RP2040), 74HC595 SIPO registers, 74HCT166 PISO registers, and some glue logic and passives.
+
+The board is designed to help me analyze and dump various types of PLDs and memories.
+
+![Rev. 1 PCB](pics/rev1.png)
+
+Various adapters (or "pods") can be designed to suit different types of ICs. The pods will be plugged in the ZIF42 socket.
+
+## Software
+
+### Firmware
+
+See [here](https://github.com/DuPAL-PAL-DUmper/dupico_firmware) for details.
+
+## Hardware
+
+The board was designed with [KiCad](https://kicad.org/) EDA.
