Adding 32-bit compatibility for old and very old binaries

I have a stats package 32-bit binary (P-Stat) which is no longer produced (this is the last version ever). I run this successfully by adding sudo dpkg --add-architecture i386 sudo apt update sudo apt install lib32stdc++6 lib32z1 lib32ncurses6 I did this after installing Linux Mint 22, and have also done so successfully on older 64-bit systems. The /lib/ld-linux.so.2 interpreter is present on the system, corresponding to the details from running the file command on the p-stat binary. I have now been sent an even older version of the P-Stat binary to test on some very old data formats, and file says it needs /lib/ld-linux.so.1 which I don't have [yet]. Two questions: 1. can I have both ld-linux.so.1and ld-linux.so.2 present on the same system? 2. what do I need to install to get ld-linux.so.1?
