All, Finally got an AIM-65 I've been meaning to sell wrapped up and listed: https://www.ebay.com/itm/275425213541 This one was used in some industrial control application and had custom ROMs in it when I received it. It was also missing the plastic display mounting blocks, so a friend of mine measured his and 3D printed replacements. The displays were gone through and a number of bad ones replaced. The main board had to be basically entirely resocketed. The flex cables to the display board were of course crumbling, so they were replaced with two new Nomex jumpers. The printer works but has two columns which are light. I don't know if that's just that the paper I had that fit it was ancient (out of my HP 5150 thermal printer, which I don't have working yet) or if the printer is weak in those two columns. Thanks, Jonathan
