If I wanted to vibe code something like Photoshop, I would start with the source code for version 1.0 [1].

It’s written mostly in very readable Pascal with some 68000 assembly.

For those not familiar (or not old as me), Pascal was popular in 80s. The syntax is clean and is strongly typed, which I understand LLMs like.

LLMs are good at converting programming languages; it probably wouldn’t be that difficult to convert it to Swift, Rust, etc.
