Some books and articles:
[1] Protocol by Alexander Galloway
[2] 10 PRINT CHR$(205.5+RND(1));:GOTO 10 by Nick Montfort et al
[3] On "Sourcery" or Code as Fetish by Wendy Hui Kyong Chun
[4] The Exploit by Alexander Galloway and Eugene Thacker
I can list many more.
There was also a doctoral seminar taught by Alexander Galloway at NYU in 2010 called The Politics of Code. The reason Galloway's name pops up a ton is that he worked with r-s-g.org and has a fair amount of experience coding in addition to his academic credentials in literary theory.
I've never used an MSX or C64 before, but since I'm interested in generative art, I've became curious about these program when a book with the same title was released:

Feeding Back: Conversations with Alternative Guitarists from Proto-Punk to Post-Rock by David Todd

Rise of the Videogame Zinesters: How Freaks, Normals, Amateurs, Artists, Dreamers, Drop-outs, Queers, Housewives, and People Like You Are Taking Back by Anna Anthropy
Some interesting ideas; the referenced tech is now dated. It's even easier to make games now then when this book was published.
