Changing wire-wrap configurations on DEC circuit boards

Hi there,

I've got a couple of DEC QBUS boards (including a quad SLU) for which
configuration is set by wire-wrap jumpers. I don't have a wire-wrap tool,
and have found that trying this by hand without one is not workable.

Has anyone come up with a clever way to permit reconfiguration of these
boards without semi-permanent changes? Or, alternatively, what wire-wrap
tool would you recommend?
