OK, I think I'm ready to do a retrofit to at least 2 machines now. Price is of great importance so, to date, it looks like EMC2 and Mesa boards.
I can find bits and pieces about doing this particular retrofit but nothing on the 5th grade level.
Can someone point me to a more detailed site or give info on cost and complexity of this retrofit?

TIA
