found the izek operation software cart and taikyoku renju at a pawn shop here in los angeles the other day. didn't think at the time to look for the sewing machine itself. (didn't know anything about it until i got home and websearched and found, among others, the assembler write up.) $10 each but i don't mind that too much...
My mom used to work for a sewing machine store, and I played with one of those once. If I ever wanted to sew I woulda used that.
