Hi everyone,

does anyone on this list have a pointer to a (freely available) JEDEC
file disassembler that also supports N82S153 (PLS153) or at least a
document showing which bit in the JEDEC file maps to what fuse in the
PLS153?

Unfortunately, also the N82S153 datasheet on alldatasheets.com doesn't
really help (unless someone could confirm that the order of bits in the
explained TWX format is the same order as in the JEDEC fusemap).

Regards,
Rainer

You might look for simulation models of it. I've seen vhdl models for
PALs, etc. that read the jedec file and configure the model
accordingly.

While they may not "disassemble" the file to the higher level you
want, at least you could configure an emulator with it.

Didn't find any. But since I had a JEDEC file at my hands where I also
possess the equations, it was rather simple to rev-engineer the fusemap
as laid out in the JEDEC file.

Not sure why you are using JEDEC for this. If you have the 82S153,
just put
the device on the programmer and read the fuse locations back. I did
this
many times 25 years ago. What device programmer are you using?

Uhm, yes. And which format but JEDEC do you suggest?

Data I/O Unisite.
