Now the other issue is capacitors that begin to leak after 30 to 35+ years: I haven't tried yet to "recap" these machines but... "one day". The SMD caps in the A1200 and Mac Classic will have almost certainly started to leak, and the fluid will eventually corrode traces and vias if it hasn't already. On multilayer PCBs this can make for at best very annoying repairs. Ironically the older machines like the Atari, TI and C128 are most likely fine. Those older, larger through-hole caps are generally of high quality and don't leak.
