backing up PAL chips

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 Jules
