The first main frame computer I had to work with was a DEC PDP11. It was still a little too large to call a PC. It ran at about 2meghz. The 8 inch floppy disks held anywhere from 300-600 kilobytes. The computer was not turn-key nor user friendly. To boot it you had to type in several keyboard memory locations.
The opsys was loaded on a floppy.
When they went to a hard drive (a ten megabyte Western Hard drive w/ 10k hours mtbf) we thought we were in hog heaven. They did make a cardinal error though.

Afterwards they did install firmware for it to look for boots on the floppies.
It is amazing to see a single thumb drive holding just 16 gigabytes of data that would have taken more than 11,665 double sided floppies to hold. This is not to mention trying to load a program that needed 15-90 floppies and expecting no read errors.

At any rate we decided that a compression test was in order so we could verify the internal engine status. That way we wouldn't buy any tune up parts until we were sure that the engine was in reasonable mechanical condition. Our tests showed a fictional compression reading of 85, 80, 82 and 86 psi. That is well within a
