I remember Goupil computer where the year in BIOS was on 4 digit and can be set from 0000 to 9999.
It was computer with memory on large cards and one with 4 cards to obtain 16MB RAM.
Too bad, this good constructor wasn't helped, and closed. So, there was the bad (worst?) constructor providing computer for schools.
Same for OS, or other technology like betacam vs VHS.
