OT (Sort of): Programming algorithm for PALCE devices

Pardon if you've heard this before, but... I'm looking for the programming algorithm for Lattice/AMD/Cypress old PALCE devices. I've got a bucketload of them (mostly PLCC) and I'd like to do something with them or trash them, if no luck in the programming department. I've found algorithms for the PEEL devices as well as NS type plain GALs, but nothing on the PALCEs. I know that programming info is usually supplied to OEMs under a NDA, but the technology has passed through a sufficient number of hands that it's hard to believe that nobody has any information. Note, unless it's very cheap (i.e. it costs less than thowing the PALCEs out) I'm not interested in another programmer, but I'm not opposed to tinkering a bit. Thanks for whatever help, --Chuck
