Paid too much for a vintage copy of Machine Language Routines for the Commodore 64/128, but still glad to have it. ML fundamentals are not hard to figure out, but mastery requires experience. I like to read code by others to see what I’m missing—and what I’m not missing.
Vintage computer books are going for crazy money these days.
Add to that the crazy current international shipping costs and they really do become personal treasures once acquired. :)
