backing up PAL chips

[Jules Richardson]

what's the most sensible format for backing up PAL chips such that they can be 
  recreated on a different system to that which they were backed up on?

My standalone EPROM/PAL unit seems to understand the following data formats:

   ASCII
   binary
   motorola s rec
   intel std & 8086
   elan fuse map
   jedec
   mos tech
   texas tags
   tex hex

... some of which are presumably EPROM-only formats (I don't have a manual for 
the programmer)

is there some sort of common format/size for PALs too when reading (akin to 
always being able to read a 27128 EPROM as a 16KB device regardless of who 
actually manufactured it)?  I'm concerned that this programmer might be too 
old to have data on some of the PAL chips that I want to archive - but if I'm 
only interested in archiving them (and so can set the type to something of the 
right 'geometry' from a different manufacturer) that's not necessarily that 
big a deal.

Advice appreicated :) I'm used to working with EPROMs, but PALs are a total 
unknown to me!

cheers
