Just a couple of days ago, I was wondering about the origin of the prefixes HSS- and HST-, used in the model/catalogue numbers of Japanese consoles and games respectively peripherals and systems. I could have believed that HSS stood for Hwatever Sega Saturn, if it weren't for HST directly contradicting this idea.  although Black Squirrel, combined with my mistake I just scored out, make me feel dumb for not thinking of SaTurn [/edit] Lo and behold, today, one of the many fruits (I exaggerate tremendously) of my wanderings on the internet: Does this explain their origin? If this is a silly or old question, for example having been discussed to death in one of you guys’ big threads, then oops. But I'm interested to know either way.
