References works for DEC hardware

You can find online manuals by searching at http://vt100.net/manx but that searches document titles only. There is a scan of the Options Module List (aka the Dick Best list) but I don't have a pointer. Be warned it's 1000s of pages long and is scanned but not OCRd (I'm probably not the only one to have tried and failed ...) but if you can get it you may find it helpful. As for microfiche, there's plenty (just look at ebay) but noone has yet started to scan that. You can also fire up the usual search engines and just hunt for your 2-5-2 part number and see if anyone else has already asked (be sure to use deja to search newsgroups too). You can obviously ask here too (although doing some leg-work up front never hurts!) Antonio -- --------------- Antonio Carlini arcarlini(a)iee.org
