My buddy just picked this up, and since he's not on here i thought I'd share. It has a mid'84 build date.
It runs real well, and a pretty cool little machine.
I've gotta do some more reading about them, but any info is welcome.
Looking to help out a buddy that is the owner of the machine in the pics...
Anyone have a seat pan for an ALT50, or any info for what models shared parts?
