+kheller2 Posted August 5, 2018 Share Posted August 5, 2018 I'm not an Intellivision gamer by any means but i do happen to have two nice units and recently considered selling them along with maybe two dozen or more boxed games. I noticed one was a 2609 and the other a 2609A. I have yet to find any technical details on the difference between these two units other than an off handed mention they use different screws. I didn't see anything in the FAQ either. So what is the difference? I also noticed that the controllers fit snugly into the 2609 but not the 2609A plastic. On the 2609 they almost become part of the case, where on the A they extend out the side just a hair. Also, of the four controller (two on each unit) one of them does not have a lip at the top of the controller but is rounded smooth. And I also noticed that on the 2609 unit the controller cables are excreting an oil but the 2609A's are not. These units have been packed away and stored in climate controlled rooms for decades, so I don't think its an environmental issue. Quote Link to comment Share on other sites More sharing options...
mr_me Posted August 5, 2018 Share Posted August 5, 2018 (edited) What are the serial numbers of the two units? The 2609A should be Intellivisions manufactured in Hong Kong (or Taiwan) for the US market. Serial numbers are larger than 300k. The 2609 should be the early Intellivisions made in the USA. Serial numbers under 180k. Perhaps yours is one of the earliest because it lacks the lip on the controllers. Sounds like there are some other subtle differences. A 2609 made in Hong Kong should be an Intellivision for the Canadian market and have a serial number over 1M prefixed with RH. There are some rare US models made in Hong Kong with serials starting at 4M. As far as I know they should all have the same Exec ROM inside, and the same sound chip. Over time there were some minor changes to the mainboard e.g. number of ram chips. There were also sone changes with the power supply board as indicated by the maintenance guide. Not sure if that has anything to do with some models saying 15W others 18W. Edited August 5, 2018 by mr_me Quote Link to comment Share on other sites More sharing options...
+JasonlikesINTV Posted August 5, 2018 Share Posted August 5, 2018 (edited) The SN Database may be of some help, although it doesn't distinguish between 2609 and 2609a (all are listed as 2609). http://www.intellivisionrevolution.com/serial-number-database-mattel-intellivision Intvfunhouse also has a helpful page: http://www.intellivisionrevolution.com/serial-number-database-mattel-intellivision Edited August 5, 2018 by JasonlikesINTV Quote Link to comment Share on other sites More sharing options...
