Title: Reprogramming a Icon IC-745 ram board
Post by: The Radio Shop on December 10, 2017, 03:43:20 PM
This is a project I will be working on. There were several DOS base programmers made to read and write the content of the ram boards for the 745 and 751 radios.
The problem is they were all DOS base and used the computers printer port to send and receive data.

What I like to do is come up with a USB based programmer to do the same.

I will be adding lots of files and pictures to this thread over the next few days.

Followed along on the EEVblog and saw that you were successful in duplicating the 745 ram board.
Will you be making these and have them available for general purchase or only for use in radios that come into the shop?

Regards.

I'd also be interested on the adapter board to interface the RAM boards to the TL866ii plus. I have an ic-751 here I am working on and also an IC-R71A.

Good night!. My name is Federico (LU1XCF) I am writing to you from Rio Gallegos - Argentina. The information that I am seeing on this site is very interesting and very useful. I came here trying to gather information about the programming of the Icom ic 751's RAM board, only the board that belongs to a 751 came to the laboratory, which lost all functions due to the battery being desoldered from the board. I built the interface to be able to record the card again, use the diagram mentioned by The Radio Shop and use the ICOM-RAM.EXE program, I tried it with windows XP SP 2 and with Free DOS without obtaining results. Could you tell me if ICOM-RAM.EXE worked for you? Since already very grateful for the information. I remain at your disposal ..
