Early IDE interface for ISA bus, 1990

I'm doing a bit of cleaning out of my collections (making space for a Data Point 2200) and one thing I found was an early IDE interface. I can't find out anything about where it came from and the silk screen says "Rev 0.0" and the pal program version is V1.0 Date codes on the IC:s points to an early 1990 date for manufacturing. I tried to find out some more about the development of the IDE interface and the two dates I found was Compaq introduced the first computers with IDE controllers in 1986 and the first standard was finalized in 1994, putting my card in the middle of that span. I put it on eBay to see if there is any interest for it and to show some pictures of it. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=111203086292 Any one recognizing it? Is it just a generic card or does it belong to a specific computer? /G?ran
