You could try having an LLM port it to Linux :) As an aside I was always (well, no longer) hoping that Photoshop gets ported to Linux because at least an IRIX port existed, so there has to be some source code with X11 or whatever library code.

If it uses Motif and IrisGL (now MESA3D) the amount of porting effort it's near NIL.
And, for purity/completeness, avoid Maxx Desktop and/or NSCDE; EMWM with XMToolbar it's close enough to SGI's Irix desktop.
As an experiment, I gave the source zip file to Claude and told it to make a WASM version of the app, by translating the Pascal to Go.
It nailed it, first try.
I cannot, unfortunately, share a link to the website it created because of the license.
LLM translations of historical software to modern platforms is a solved problem. Try it, you'll see.
I used https://exe.dev/ and their Shelley agent to drive Claude. Give it a try, it is jaw dropping.
Photoshop was ported to IRIX using Latitude, Quorum Software's implementation of Mac OS System 7. Apple later acquired the Quorum's code and it became part of Carbon.
