Image of CBM 710
I found an image of a CBM710 on Wikimedia, and after searching for more information on the net, I found this page who, unless I am mistaken, states the machine as a CBM II range computer, so I've inserted it. Hope that is ok. --AndersL 21:16, 19 November 2005 (UTC)


 * OK, indeed; Thanks for adding the image! --Wernher 06:38, 20 November 2005 (UTC)

European CBM series only?
The article states that "An optional Intel 8088-based coprocessor board allowed the CBM series to run CP/M-86 and MS-DOS 1.25" Does anyone know if that was only european cbm models, or was it also true for american models as well? --AndersL 20:10, 20 November 2005 (UTC)


 * The two external link resources (of which you supplied one) seem to indicate that the 8088 board was available on some models both in the US/CAN and Europe. However, one needs to look really closely at the docs to determine which machine configs with 8088 boards were sold commercially and which were just prototypes (or quickly cancelled models), in whichever market... Good luck to you; CBM 'historian' that I might be, I'm actually not sure I really want to know that much about all those details! I'm trying to get a life as well. :-) --Wernher 03:15, 22 November 2005 (UTC)


 * These boards were never sold. ALL are engineering prototypes only.  The largest cache was turned over to CBUG in the United States in 1987 when the Commodore plant in Corby UK was closing down along with boxes of schematics, MS-DOS 1.25, CP/M-86 1.0 and 1.1 prototype images.  How do I know?  I was a member of CBUG and I have two of them still from the original hand off to members then.    ;-)   http://www.insectria.net/b128.html  69.165.232.107 13:57, 18 March 2007 (UTC)

Merge proposal with CBM-II
I wasn't the one who proposed this, but I entirely agree with the proposal- it's a no-brainer, two pages covering exactly the same subject. Ubcule (talk) 13:33, 26 December 2008 (UTC)


 * The merge proposal has been there for around 2 years(!!!), even sillier and more annoying is that it was created as part of the first set of edits by that article's creator(!). There is no way it shouldn't be merged, though most of the content seems to be covered already here anyway. At any rate, that page is now a redirect. Ubcule (talk) 22:04, 10 March 2010 (UTC)

Content of old CBM-II article
Here's the content of the CBM-II article as it was before the page was redirected here.

The CBM-II was a series of personal computers sold by Commodore International from 1981-1987. The line was intended to replace Commodore's successful PET series. The model nomenclature of the series is confusing, as Commodore released models under many designations for different markets, including the PL series, but the B-series is probably the best known. The PET case was updated to a striking rounded futuristic look which caused it to be seen in a number of TV and film productions, including Star Trek: The Wrath of Khan and Buck Rogers in the 25th Century.

There were many models planned but never produced due to the runaway success of the Commodore 64 and Commodore's subsequent concentration on the home computer market. The CBM-II series was geared toward the business market, but its aging 8-bit architecture and the introduction of the IBM PC also in 1981, meant the machines were not to be successful. The entire line was discontinued around 1984 and remaining inventory liquidated through Protecto Enterprises which ran black & white ads in computer magazines for many years selling complete B-128 systems at low prices. In 1987, Commodore turned over all materials relating to the B-series and CBM-II to CBUG, the Commodore B-series User Group. Among these materials was a prototype motherboard using an Intel 8088 processor, which hints at the possibility the line could have been made IBM compatible if production had continued.

Time Travel
The Commodore VIC-20 was released before the CBM=II so i have changed the Successor to "none" from "Vic-20". —Preceding unsigned comment added by 213.163.72.149 (talk) 04:42, 2 August 2010 (UTC)

6x0 vs 7x0 machines?
What's the difference between the 610/620 one one hand and the 710/720 on the other hand? It's not memory size, as that is handled by the ...10 and ...20 numbers for 128K or 256K respectively. And what are the 620+ and 720+ machines listed e.g. in VICE? Thanks for any clarification! -- 84.63.237.45 (talk) 20:35, 26 December 2011 (UTC)
