We've got a computer in the lab from the 70's that we use to upload firmware for some legacy chips still in service on aircraft (a cabin lighting system, not anything vital to the aircraft staying in the air!). I dread the day that it breaks because it's all bespoke software and hardware. We tried to back it up to another device but it's simply not compatible with anything except that computer. When it finally gives up the ghost it's likely going to cost thousands to design a new system with modern hardware, which doesn't even include the cost of writing up all the new safety documentation and grounding the aircraft for a refit! To add to the headache, it's all written in BASIC so the only ones who knew how to do anything with it have long retired or passed away. I don't look forward to the day I have to reverse engineer that bad boy.
