Editing Commodore 64 (section)

=== Third-party books ===

Sixty-nine third-party Commodore books are hosted on this wiki; [[:Category:Commodore Books]] is the annotated index. Almost all are programming or games books with no hardware content at all, and none should be cited for a component value. '''Four of them do reach the hardware''':

* '''[[Troubleshooting and Repairing your Commodore 64]]''' &mdash; Art Margolis, TAB Books, 1985, 377 pp. Twenty-one test point charts and a master schematic in the appendix.
* '''[[Commodore 64 Troubleshooting and Repair Guide]]''' &mdash; Robert C. Brenner, Sams, 1985, 183 pp. Symptom-first diagnosis, a power supply chapter and a chapter on testing capacitors.
* '''[[The Commodore 64 Kernal and Hardware Revealed]]''' &mdash; Nick Hampshire, Collins, 1985, 213 pp. Reproduces Commodore's own schematic by permission, and traces the cassette motor supply and its output waveforms.
* '''[[The Anatomy of a Commodore 64]]''' &mdash; Data Becker / First Publishing, 309 pp. Chip level rather than board level: the 6510 and the 6526 in detail and a full ROM listing, but no schematic and no parts list in this edition.

All four are secondary sources. Where any of them disagrees with Commodore's service manual or technical manual, those are primary. '''No figure on this page has been taken from any of them.'''

Two more are worth naming for what they are:

* '''[[DIY Robotics and Sensors]]''' &mdash; John Billingsley, Sunshine Books, 1984, 141 pp. The only book in the collection that is about '''electronics''' rather than software, and it documents the '''user port and the analogue port from the outside''' &mdash; signal levels, data direction registers, address decoding, and analogue output from CB2 on the PET. It contains no Commodore schematic and no component value for any Commodore board; its circuits are the author's own designs for things to plug in.
* '''[[Machine Language for Beginners]]''' &mdash; Richard Mansfield, COMPUTE! Publications. Its Appendix B holds the '''Commodore 64 memory map''', but '''the scan hosted here is missing about 117 of its 350 printed pages''', including the PET/CBM and VIC maps and the PET 4.0 ROM routine list. The gaps are documented on that page.
