This PB1400c/166 boots fine and installs 8.0, 8.1 and beyond, but I cannot get to boot off 7.6. I also redownloaded all 1400 specific 7.6 from Macintosh garden. I also tried to install a clean install from those CDs after booting off 8.1, but either way the 1400 says that the system os not correct. I am wondering if late 1400c requires 8.0.

PowerBook 1400c/166 does not boot specific 7.6

the 4400 is a good example, I don't think it booted any version between 7.5.5 and 7.6, but it would boot 7.6.1 through 9.1

Sounds strange.
Can you check in System Profiler in Mac OS 8.x? See what the GUID is? Make sure it is reporting correctly.

According to Everymac, the 1400 only works with 8.0-9.1, so try installing 8.1 onto it, as 8.0 was originally going to be Mac OS 7.7 (long story involving Steve Jobs and the clone market), and is pretty similar to 7.6 or 7.6.1

Are you sure? The everymac page I can see says 7.6.1 and above for the 1400c/166.

that makes a bit more sense, I was looking at the page for the 1400cs/166

I'd imaging that would boot 7.6.1 too, it just says 8.0 because it shipped with it, but they have the same gestalt, so the OS wouldn't treat them differently.
8.0 is fine, its 7.6.1 the problem

***Apologies in advance if the following doesn't make sense 100%. I'm way past my bedtime....***
What is most peculiar here is that the 1400 was released in October 1996, which is a little under a year before the release of Mac OS 8 (July 1997), so by all rights, 7.6.1 should work, unless your machine is a post-July 1997-early 1998 machine, and such machines are somehow locked out of booting 7.6.1? That would make sense, given your experience so far, but we need more data to figure that out because it seems kind of far fetched. More likely is that later units shipped with 8.0 simply becasue that was the then-current version, and 7.6.1 had been discontinued, but again, we don't know without more information. For now, it's only speculation on my part.
That being said, can you confirm the manufacturing date of your 1400c/166 somehow? That would probably be a good place to start....

The date of manufacture shouldn't matter. OSes only generally didn't boot a computer if the OS didn't know what the computer was, and unless there was a significant hardware change, or the gestalt changed, that wouldn't be the case here.
