Haha, seconded. That list got expanded as well to allow for multiple byte (segment) IDs, and the expanded list still feels like a blast from the past! The only thing about MIDI is that the official standard doc is still only officially available as dead tree. While there's plenty of good (and sometimes better) treatments of it online, I wish they'd just catch up a little - I don't really want to send a cheque from the UK to Cali' for it!
Of course, that's rather a digression - it's a surprisingly decent standard, and what it's enabled is startling. Well deserved, and congratulations to them!

It's like a 1970's and 80's time-capsule.
