Editing Commodore 65 (section)

===Chipset names===
The custom chips of the C65 were not meant to have names like the custom chips in the [[Amiga]]. Although there are names printed near the chip sockets on various revisions of the circuit board, they were not intended as names for the chips. According to former Commodore engineer Bill Gardei,<ref name="cccom_bill">{{cite web|title=The Story Behind 'Bill' and 'Victor'|url=http://collectorcomputers.com/truthaboutbill.txt|date=2013-11-16|access-date=2013-11-16|publisher=collectorcomputers.com|archive-url=https://web.archive.org/web/20150610201234/http://collectorcomputers.com/truthaboutbill.txt|archive-date=2015-06-10|url-status=dead}}</ref><blockquote>The Legend on the PCB was to let others in the organization know [whom] to go to for advice on the chips. We did have an issue with that. But that wasn't the name of the chip at the time. The 4567 was always called the VIC-3. I can see why others outside of Commodore made the connection. But again—no—we never called these chips "Victor" or "Bill".</blockquote>The custom chips for the C65 are:

* CSG 4510: processor (commonly called "Victor" after Victor Andrade)
* CSG 4567: VIC-III graphics processor (commonly called "Bill" after Bill Gardei)
* CSG 4151: DMAgic DMA controller (designed by Paul Lassa)
* F011C: FDC (floppy disk controller, also designed by Bill Gardei)

The C65 also contains one or two programmable logic arrays depending on the version:

* ELMER: PAL16L8 (C65 versions 1.1, 2A, 2B), PAL20L8 (C65 versions 3–5)
* IGOR: PAL16L8 (C65 version 2B only)
