I mean, yes, there is documentation, but not the kind you would have had access to as a developer with access to the project internals.

Realistically, “from scratch” back then would have been a lot easier – here, you are having to do detective work on defective material from decades ago, with no access to the developers or to most of the documentation. That’s in no way “easy”.

For the Altivec acceleration, I remember TenFourFox once made a point of advertising that it had used it in a _lot_ of places, including some you just described as not amenable to vectorization, which makes me wonder how that was done. I don't know how relevant or useful this observation may...

What company made THAT? Never seen such a thing before.

Nicely done! Those tube clamps come in many slightly different sizes, so congratulations on finding an appropriate specimen. (It seems like I am always short on whatever size I happen to need at work!)

Meh, I'll rather spend my pennies on the guy who's actually doing the work before I patronize a “zero-value-added” seller. Seems only fair. Open-source hardware is meant for people to improve on the original, not just to act like concert-ticket scalpers and undercut actual development.

Is there a link or something for that? I checked this thread, and the other thread linked above, and all either one said was "it's for sale" (and the price). I've never used Tindie. Heck, I'm not sure I'd ever HEARD of Tindie before this. I'm assuming it's a dot-com rather than a .biz or...

Could “BurstCap” be short for “burst capability”?

It says on the left: "20 - connects to: DDC - 16" – but the right side says DDC is 17, with 16 being SDA.

Provisionally, yes, but I don’t manage to get my classic Macs out for exercise anywhere near as often as I’d like. :¬)

The only complicating factor would be whether ot not any larger data structures are defined to incorporate a 32-bit date. You'd have to track down and redefine ALL of them as part of the first item on that list I just gave.

I've been thinking about this, and in my opinion the "general case" solution would have to be something like what Apple had to do when moving beyond 4GiB disk volumes: Implement a larger data structure that can handle wider values (say, 48 or 64 bits); implement a Gestalt selector to indicate...

It starts with higher IDs because that's how SCSI is defined – barring a reason to think otherwise, higher IDs get priority.

As far as I'm aware, it is an ADB connection - they just wouldn't have bothered making the Reset connection on a device that doesn't use it.

When you write MAC in all caps while discussing low-level components, I keep thinking you mean a Media Access Controller chip or similar, but from context you appear to be talking about the Macintosh as a whole? That’s needlessly unclear.
