Editing Dragon 32/64 (section)

== Differences from the TRS-80 Color Computer ==
Both the Dragon and the [[TRS-80 Color Computer]] are based on a Motorola data sheet design for the MC6883 SAM (MMU) chip for memory management and peripheral control.

The systems are sufficiently similar that a significant fraction of the compiled software produced for one machine will run on the other. Software running via the built-in Basic interpreters also has a high level of compatibility, but only after they are re-[[tokenize]]d, which can be achieved fairly easily by transferring via cassette tape with appropriate options.

It is possible to permanently convert a Color Computer into a Dragon by swapping the original Color Computer ROM and rewiring the keyboard cable.<ref>{{Cite web |url=http://www.onastick.clara.co.uk/cococnv.htm |title=Coco to Dragon Conversion |access-date=5 August 2008 |archive-url=https://web.archive.org/web/20091126225659/http://www.onastick.clara.co.uk/cococnv.htm |archive-date=26 November 2009 |url-status=dead }}</ref>

The Dragon has additional circuitry to make the MC6847 VDG compatible with European [[Lines of resolution|625-line]] [[PAL]] television standards, rather than the US 525-line [[NTSC]] standard, and a [[Centronics]] parallel printer port not present on the TRS-80. Some models were manufactured with NTSC video for the US and Canadian markets.
