Some days ago I dumped the PALs from a pretty rare board : Money Money by the italian Zaccaria manufacturer.Here’s how board looks like:

Devices were three secured PAL16L8.I reversed two of them in a GAL16V8 while I was able to fit equations of the third one in a GAL22V10 (so tie pin 10 to pin 12 of the IC when installing the replacement in a socket).
