Cartridge processors are quite likeable. Easy to identify processors, don't need to bother with thermal paste, compatibility is usually good.
Plus the processors just look cool. There's a sense of packaging style that chip manufacturers don't have anymore.
I remember years ago, when I first started with old computers & stockpiling old parts... I was telling everyone how Slot-1 systems are going to be obsolete & difficult to find one day, and also how their value will exponentially increase over time, to the point where they'll probably cost a fortune, again. But people didn't seem to share my opinion & they've been telling me how something like that isn't going to happen due to the huge amount of remaining systems (and parts), which is considerably dropping down their marketing value. Even among collectors.
10-ish years later, I would have to disagree with their statement! It would seem I was right all along, and that Slot-1 really is next in line to become highly desirable, but difficult to come across sort of hardware ... just like 3dfx! It'll certainly be interesting to see the the situation development throughout the next, let's say 3-5 years from now!
And let me tell you this - the very same thing will happen to ALL the "vintage" platforms out there. Socket 370 is the next one after that, so if you (or anyone else, reading this) ever considered to stack up on S370 hardware, now it's the time to do so. As for the AMD, they already have the advantage as Slot A boards & gear is now seriously rare stuff & highly desirable piece of equipment. Socket 462,A will probably take a while longer due to the same reason as Slot-1, but they'll eventually get there.
