The first sentence states the VCPI spec was published in 1989. The final sentence states the "Extended" VCPI (XVCPI) spec addressed some issues with the original spec "in the late 1980s." Are both of those time references accurate? If they are, maybe "later that same year" would be more apt for the final sentence. PlaysWithLife (talk) 07:54, 27 August 2011 (UTC)[reply]

XVCPI?

I removed the following unsourced paragraph from the article: "In the late 1980s an extended version of the specification XVCPI addressed some of these problems and was implemented or used by a small number of products including Interactive Unix and Digital Research operating systems.[citation needed]" This has been flagged with "citation needed" for 1.5 years now and the original contributor in 2010 ([[1]]) didn't respond to my query as well. Although there might have been proprietary extensions to the VCPI standard I am quite sure a standard named XVCPI never existed. It remains unclear, what could have been meant by this. --Matthiaspaul (talk) 18:54, 21 May 2013 (UTC)[reply]

I have reverted myself and expanded the XVCPI section since I found "Extended VCPI" and Intel briefly mentioned in the DPMI 1.0 specification. Mark was able to locate some information on the XVCPI API entry point (INT 67h AH=DEh, as VCPI, with currently known subfunctions AL=40h and AL=43h) and three involved companies (Digital Research with Concurrent DOS 386, Interactive Systems with Interactive Unix, and Viewport). This may help us to find more detailed and reliable information in the future. --Matthiaspaul (talk) 21:52, 27 May 2013 (UTC)[reply]
