It did, the earlier ones like the VT05 (and perhaps the VT50/52) didn't as far as I recall. They had a ton of boards with a whole lot of discrete logic! A bit like the early computers where the 'processor' was not a chip but also several boards with discrete logic chips.
As a result, those earlier terminals are even harder to emulate as there wasn't really much 'firmware' and definitely no standard CPU architecture. However those were pretty barebones anyway in terms of control codes.
I loved the VT05's design though. It looks really star trek. It won't fit on a modern desk because of the depth (all those custom boards take up a ton of space) but it looks so cool.
