T series adapter card list

I am attempting to compile a list of the Txxx cards commonly found in 6000 class machines. I have info on quite a few, but either sketchy or meaningless descriptions of some and a cryptic name or even nothing for others. I seem to recall an online database of these, but I am unable to find it in any of my bookmarks or even in my email archive. I am currently searching the Digital/Compaq sites, but not finding much of use so far. Several resellers list the cards by number and some even have descriptions, but I was hoping for something more complete. For instance, an XMI 32Mb ram card is a T2014XX where XX is a 2 letter suffix detailing (I think) the speed of the ram and therefore it's suitability for a particular model. A full explanation of what these mean would be good. Any help appreciated, acknowledgements given etc. Cheers Geoff Roberts Computer Systems Manager Saint Mark's College Port Pirie, South Australia geoffrob(a)stmarks.pp.catholic.edu.au netcafe(a)tell.net.au ICQ: 1970476
