6. Do a hard copy printout of the BIOS. Its flash memory will have become erased in 50 years.
7. Dito for any BIOS in your video hardware
7b Ditto for the hard disk and cd/dvd-reader (their integrated controllers have their own firmware stored on flash eprom) and check if the rest of the hardware has other microcontrollers with firmware on flash eprom.
The best strategy is to store on cd/dvd the bios, firmware and all the documentation for the programming interface (usually JTAG) and the exact protocol and procedure needed to reflash the chips from scratch (usually you find them in.pdf format in the technical documentation of the chip manifacturer).
Better if there are multiple copies on different disks of exactly the same data so even with damaged or "faded" disks it will easier to perform at least a partial recovery by comparing the disk content .
