I'm gonna suggest they both were hand drawn as duplicate letters were sightly different: A and O on this one.

I suppose the irregularities are due to a scan (?) of the t-shirts.

Looks like a distorted and slanted version of Techno by Dave Berlow.

It's definitely distorted from the scan of the shirt. I would say it's Techno now that I see it. Does any one have this? It's apparently on the newer macs, so I don't have it with my system. Any help would be appreciated.

Nope, it was part of the 9.x systems …
