I am an EE looking for the EPROM image of prom #40 (the lower one) on the CP-07 board of a MV Junior. I managed to wipe mine, before I realized that I did not have a good image of it. Bonehead move, I know.... I had previously imaged all of the EPROMs in the whole machine, for a rainy day, and that day has come. Unfortunately, EPROM#40 is a 27c256, while all the rest of the EPROMs are 27128's -- When I previously imaged the EPROM#40, I only read out half of it! - I wish I had paid more attention. So, to make a long story short, I need an image of #40 on CP-07. This is called the "ladder software" EPROM, (it ruins the ladder logic CPU on the CP-07) I will trade / share all of the other roms that I imaged for this, and I am willing to help others repair/give advice on the MX-2 (I have spent a TON of time reverse engineering the dam thing thanks to Yaskawa's totally-closed mouth nature of tech support) Thanks, ---Lou |
