NMI Parity Errors while Parallel Printing

[Bob Ames]

Anybody seen this?

We've got a 3B1 which panics with NMI parity errors after 2-10 lines
have printed through the parallel Port.

Starlan printing works fine.  We've tried other computers with this
printer/cable and they print OK.

I developed a theory that somehow the parallel port drains some power
and causes memory to forget.  I'll probably get 20 letters from people
telling me how silly this theory is.  |-)
