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,
