O.K., I'm back.  The ZIP drive works just fine.  With USB debugging turned
on in the kernel, I'm getting all kinds of STALL messages from /dev/ulpt0
when I try to send to the Z51.

Curiously, I haven't gotten some of the message traffic
intervening--probably my buggy ISP again.  Anyway, I think the Z51's USB
port just doesn't want to play.  Back to the drawing board . . .
