A R71E RAM board programmer based on Arduino Uno

[rz]

BI1EIH and I designed a programmer for EX-314 RAM board which was used on IC-R71, IC-745, IC-751, etc. It's base on Arduino Uno with an adapter to connect EX-314 to Arduino. The project is opensourced, hope it can bring convenience to rescue the old rigs.
The ROM in the source code is dumped from my R71E. If you have IC-745, IC-751, IC-271, IC-471, IC-1271, you can share the ROMs here.

Usage
1. Connect ICOM EX-314 to the adapter, then plug the adapter on Arduino Uno.
2. Connect serial port on the adapter to computer, if the details of the backup/restore process are needed.
3. Power on the Arduino Uno.
4. Click the button on the adapter to dump the data of EX-314, output to serial port and backup the data to EEPROM simultaneously.
5. Press and hold the button for 1s to restore the data in EEPROM to EX-314.
6. Press and hold the button for 5s to restore the original data in the program to EX-314.

Hope you enjoy it.

Hi,

I have a couple of questions.

First of all, while I am computer literate, I am not at all familiar with the Arduino.  Can you tell me which model of the Arduino Uno the Gerber files are for?  I see different versions at our local computer store.

Also, which would be the correct file for the Icom IC-271?

Thanks for the info.

The connector footprint and pinout are the same for any Arduino UNO clone.

Great.  Thank you very much for the rapid response!

Hi,
Great job on the programmer.
One thing that puzzled me is that the dump didn't seem to make sense.
Looking at the PCB's I saw that RAM D0,D1,D2,D3 has been mapped to D3,D0,D1,D2 on the Arduino.
Makes no difference if you make a dump from a board and write it back, but if you try and use one of the dumps posted on the NET, it wont work.
I remapped your dump and put it through a decoder program that I wrote. Output as shown below. (sorry, but the spacing has gone to pot int the cut-and-paste ;



file to decode: reverse.out
Hex Dump of file reverse.out (note RAM is 4-bit wide)
