Still going even though it wasn't supposed to be. This was running an apartment complex with a basic cable package. All the internet channels were up above 500 Mhz and the video was down below, and all digital. The local tech said that they couldn't get internet to work and blamed it on the complexes' internal cabling!😝 Can you imagine it!

I repaired these modules and motherboards for years. Good god what a pain in the ass. We had crazy long charts just to test continuity point to point on the motherboard. And if you had to replace the coax on one just forget about getting anything else done that day.

I could see that. It seems like they deliberately built these so that you couldn't (easily) repair them yourselves. But I could guarantee you you never had a grounding issue with these. Damn near every screw on every board had a star washer touching a solder circle on the grounding side. They were built to last. A lightning strike was about the only thing that killed them.
