I've tried the O2 technology site (www.o2tech.com), but that URL is for sale. I've also tried the ardent software site (www.ardentsoftware.com), but that just links to www.ascential.com. I then emailed Ascential support, with no luck. They didn't appear to understand what O2 was. I've also searched Google a number of times. Anyhow, I'm wondering who has taken over support and development of the O2 object database originally created by the Altair consortium in 1986? I'm looking for ODBC drivers for NT/2000/XP that support O2.
Thanks,
Tom
