How do I erase an Altera EPM7064 with JTAG lockout

Subject says it all really.

I'd like to erase a number of EMP7064SLC44's that have
been programmed with JTAG disabled. Anyone have the
'secret formula' or the special programmer equipment
that can do it ?

As far as I know, a standard Data IO (or so) programmer should be able to do
this - assuming you can put the device into the programmer's socket. If
not, you've got yourself a problem.
