Machine Language for the Commodore 64 is selling for $75 on Amazon

[ChuckT]

If you have an old "Machine Language Programming For the Commodore 64", it is worth at least $75 because it is selling for that much on Amazon.com.  I have at least two copies but I haven't decided to sell them.  There might be gold in your old books.

Machine Language for the Commodore 64 by Jim Butterfield

Not just any book, the book. Jim Butterfield passed away recently, which created more of a demand for a book that has always been considered the gold standard anyway. I feel fortunate to have picked this book up for $30 on eBay a couple months ago. It will only go up in vlaue from here.

RIP Jim Butterfield :-(
