Editing TRS-80 Color Computer (section)

==Clones and cousins==
The [[Dragon 32/64|Dragon 32 and 64]] are British cousins of the CoCo based on a reference design from Motorola that was produced as an example of the capabilities of the MC6809E CPU when coupled with the MC6847 Video Display Generator and the MC6883 Synchronous Address Multiplexer. The [[BIOS]] for the Dragon 32 was written based on specifications and API drawn up by Microsoft and, to a certain extent, [[PA Consulting Group|PA Consulting]] of [[Cambridge]].{{Citation needed|date=August 2020}} The Dragon was a much improved unit with video output in addition to the [[television|TV]] output of the CoCo and CoCo 2. It also featured a [[Centronics]] [[parallel port]] (not present on any CoCo), an integrated [[6551]]A serial [[Universal asynchronous receiver/transmitter|UART]] (on the Dragon 64), and a higher-quality keyboard. In 1983, a version of the Dragon was licensed for manufacture for the North American market by [[Tano Corporation]] of [[New Orleans, Louisiana]]. Tano started production at their {{convert|48000|sqft|m2|adj=on}} facility in September 1983 and were running at capacity one month later. Sales did not meet expectations and Tano stopped production and support after a year.<ref>Dragon Archive History [http://archive.worldofdragon.org/index.php?title=Dragon_History Worldofdragon.org] {{Webarchive|url=https://web.archive.org/web/20100412195715/http://archive.worldofdragon.org/index.php?title=Dragon_History |date=2010-04-12 }}</ref>

In Brazil, there were several CoCo clones, including the [[Prológica CP-400|Prológica CP 400 Color]] and CP 400 Color II,'''<ref name=":0">{{Cite web |title=1000BiT - Computers list by manufacturer |url=https://www.1000bit.it/database2.asp?id=381 |access-date=2022-12-19 |website=www.1000bit.it |archive-date=2022-12-19 |archive-url=https://web.archive.org/web/20221219233750/https://www.1000bit.it/database2.asp?id=381 |url-status=live }}</ref><ref>{{Cite web |title=ITENS DO FABRICANTE: Prológica |url=https://www.velasco.com.br/index.php?fabricante=%27Prol%C3%B3gica%27 |access-date=2023-01-06 |website=Marcos Velasco - Museu de Tecnologia e Software |archive-date=2023-01-06 |archive-url=https://web.archive.org/web/20230106153437/https://www.velasco.com.br/index.php?fabricante=%27Prol%C3%B3gica%27 |url-status=live }}</ref><ref>{{Cite web |title=Sistema Brasileiro de Televisão - SBT |url=https://www.sbt.com.br/variedades/sbt-games/fiquepordentro/227389-documentario-revisita-os-games-para-primeiros-computadores-de-uso-domestico |access-date=2022-12-20 |website=www.sbt.com.br |archive-date=2022-12-20 |archive-url=https://web.archive.org/web/20221220090220/https://www.sbt.com.br/variedades/sbt-games/fiquepordentro/227389-documentario-revisita-os-games-para-primeiros-computadores-de-uso-domestico |url-status=live }}</ref><ref>{{Cite web |last=Soares |first=Gustavo |date=2022-12-02 |title=Documentário conta como nasceram os primeiros jogos de computador brasileiros - Juiz de Fora/MG |url=https://www.acessa.com/economia/2022/11/107255-documentario-conta-como-nasceram-os-primeiros-jogos-de-computador-brasileiros.html |access-date=2022-12-20 |website=Acessa.com |archive-date=2022-12-20 |archive-url=https://web.archive.org/web/20221220090225/https://www.acessa.com/economia/2022/11/107255-documentario-conta-como-nasceram-os-primeiros-jogos-de-computador-brasileiros.html |url-status=live }}</ref>''' the [[Varix VC 50]],<ref name=":1">{{Cite news |last=Scharf |first=Luciano |date=July 2019 |title=Varix VC 50 História e Legado do Mítico TRS-80 Color Nacional |language=Portuguese |pages=60–64 |work=Revista Jogos 80 |issue=21 |url=https://www.jogos80.com.br/edicoes/arquivos/jogos80-21.pdf |access-date=2023-03-21 |archive-date=2023-03-25 |archive-url=https://web.archive.org/web/20230325133106/https://www.jogos80.com.br/edicoes/arquivos/jogos80-21.pdf |url-status=live }}</ref><ref>{{Cite web |date=2016-03-03 |title=Micro Varix 50 - TRS Color |url=http://www.cobit.xpg.com.br/micros/varix.htm |access-date=2023-03-21 |website=Clube Old Bits |archive-url=https://web.archive.org/web/20160303233959/http://www.cobit.xpg.com.br/micros/varix.htm |archive-date=2016-03-03 |language=Portuguese}}</ref><ref>{{Cite web |date=2019-07-01 |title=Microcomputador Varix VC50 - Operação |url=https://datassette.org/manuais/br-brasil-hardware-trs-color-tandy-manuais/microcomputador-varix-vc50-operacao |access-date=2023-03-21 |website=Datassette |language=pt-br |archive-date=2023-03-21 |archive-url=https://web.archive.org/web/20230321102123/https://datassette.org/manuais/br-brasil-hardware-trs-color-tandy-manuais/microcomputador-varix-vc50-operacao |url-status=live }}</ref><ref>{{Cite web |title=epocalc - Computer models database |url=http://www.epocalc.net/php/liste_models.php?texte=varix&look=All+fields&yearmax=2025&nocomp=pc |access-date=2023-03-21 |website=www.epocalc.net |archive-date=2023-03-21 |archive-url=https://web.archive.org/web/20230321102115/http://www.epocalc.net/php/liste_models.php?texte=varix&look=All+fields&yearmax=2025&nocomp=pc |url-status=live }}</ref> the [[LZ Color 64]],<ref name=":02">{{Cite news |date=August 1983 |title=Equipamentos: Color 64 |pages=46 |work=Micro Sistemas |url=http://www.datacassete.com.br/uploads/revistas/micro_sistemas/micro_sistemas_23.pdf|archive-url=https://web.archive.org/web/20141022111445/http://www.datacassete.com.br/uploads/revistas/micro_sistemas/micro_sistemas_23.pdf |archive-date=2014-10-22 }}</ref><ref>{{Cite web |last=brancorp2000 |date=2021-02-17 |title=Review de um LZ Color 64 |url=https://oldplayers.com.br/wp/2021/02/17/review-de-um-lz-color-64/ |access-date=2023-03-20 |website=OLDPLAYERS |language=pt-BR |archive-date=2023-03-20 |archive-url=https://web.archive.org/web/20230320203144/https://oldplayers.com.br/wp/2021/02/17/review-de-um-lz-color-64/ |url-status=live }}</ref><ref>{{Cite web |last=Campos |first=Daniel |title=Color 64: Uma raridade carioca!

In Mexico, the Micro-SEP, a CoCo 2 clone with 64 KB of memory, was introduced by the [[Secretariat of Public Education (Mexico)|Secretary of Education]]. The Micro-SEP was intended to be distributed nationally to all the public schools teaching the 7th to 9th grades. They were presented as a design of the [[CINVESTAV|Center of Advanced Research and Studies]] of [[Instituto Politécnico Nacional]].<ref>{{cite web|url=http://blogs.redescolar.org.mx/ezequiel/?page_id=10 |title=Red Escolar y el modelo de uso de las Tecnologías de la Información y la Comunicación en Educación |access-date=2008-06-11 |date=October 16, 2006 |work=4º Encuentro Nacional de Red Escolar |language=es |url-status = dead|archive-url=https://web.archive.org/web/20071226014402/http://blogs.redescolar.org.mx/ezequiel/?page_id=10 |archive-date=December 26, 2007 }}</ref> Like the Dragon, these computers also included video output. Whether these computers were "designed" by this institute, or were licensed from the original design, is unclear.

A Taiwan-based company, [[Sampo Corporation|Sampo]], also made a CoCo clone, the Sampo Color Computer.<ref>{{cite magazine |url=https://archive.org/stream/byte-magazine-1982-11/1982_11_BYTE_07-11_Graphics#page/n215/mode/2up/search/sampo | title=Computers in Taiwan, R.O.C: Color computer and BTC-14000 terminal from SAMPO CO|page=192-22 | date=November 1982 | magazine=[[Byte (magazine)|BYTE]] | volume = 7 |issue = 11}}</ref><ref>{{cite magazine | url=https://archive.org/stream/byte-magazine-1982-11/1982_11_BYTE_07-11_Graphics#page/n199/mode/2up/search/sampo |type=Advertisement |title=Introducing a duet of SAMPO computer products! |pages=192–7 |date=November 1982 | magazine=[[Byte (magazine)|BYTE]] | volume = 7 |issue = 11}}</ref> The Sampo was supposedly available in Taiwan, Korea, and possibly other Asian countries. It is believed that Tandy blocked sales in the US with legal action due to [[copyright infringements]] on the ROM code.

The [[TRS-80 MC-10]], or Micro Color Computer, was sold in Radio Shack stores as an entry-level computer at a lower cost than the CoCo. Released in 1983, it was similar in appearance to the [[Timex Sinclair]]. Like the CoCo, it uses the MC6847 VDG and Microsoft BASIC, but with the MC6803 instead of the 6809.
