It likely would have been based on the PowerPC-based ThinkPad like laptop they produced which also ran AIX (IBM's version of Unix). like these https://en.wikipedia.org/wiki/ThinkPad_Power_Series

I was familiar with both the "laptop AS400" and the PowerPC thinkpad - these were different hardware unrelated to each other. I believe the sales demo machine was a CISC architecture demo machine that predated PowerPC, but I'm not 100% confident here. I never laid eyes on the AS400 sales demo machine but we were told about it in IBM AS/400 training school. I also had one of the PowerPC laptops running AIX for a while, nice little machines for the day.

Yes, they ran AIX, NT, OS/2 and Solaris, although the latter two only in half baked betas.

		Yes. I could not fathom why anyone would want to run anything besides AIX on them though. You can run all the other OS's on cheap commodity hardware, the draw for me was having an AIX system to work with.
