Palasm? Oops! Correction.

  I was tired when I wrote the information below and I made a serious goof.
The part that plugs into the model 29 programmer and that the PAL socket
adapter plugs into is the LogicPac and not the Design Adapter. The DA
(Design Adapter) plugs into the LogicPac in place of the PAL socket
adapter. After you use the DA to convert your logic equations to the JEDEC
fuse mappings, you remove the DA and replace it with the correct socket
adapter for your type of PAL and then command the programmer to burn the
fuse pattern. I don't think the DA is absolutely reguired, I think the ABEL
software will also compile the logic equations into a fuse mapping. However
the DA will do tests on the PALs that the software alone can't do.

  FWIW the LogicPak works with the model 29A, 29B, 19 and 100A programmers
and orginally cost $1795. The LogicPak is REQUIRED in order to read/program
any PALs.
