IBM is printed on my PA6T, but maybe TI did manufacture it(?).

I'm not saying it was poorly designed, just that the design was unimaginative.
Why not another southbridge type chip with some different functions for example.

When I say the SE/XE are not that much different from the X1k I'm speaking of functionality not 10 years of technological advancement.

Does it have a PPC CPU?
Does it have card slots?
Does it have a southbridge?
Etc.

Well, anyway that's why I prefaced my post with IMHO, and that's worth about nothing.

Too bad the PA6T disappeared. Rotten luck.
