Hello to All.. Thank you so much for the various respomses to my P 300 inquiry. In doing some research, I discovered several sites with info, but nothing specific about this model, other than someone here in SoCal who has several of them for sale ($500..... not!). I have a call in to see if they might have docs and, now that I know such a thing exists.... an RS232 or Centronics I/O card. I would like to re-iterate my previous request, though... I am interested in buying, trading, copying, or otherwise acquiring a nice set of manuals for this printer.. engineering, user, etc. I like to have the docs for stuff... it cuts down on the guess-work when they break. ;) Thanks again for all the other info... and especial regards to the individual who took the time to FAX me some critical material on VMS magtape issues... taken from an important book I don't have. Yet. I am further interested in getting a VMS 5.x Grey Wall. Purchase/ship/trade/whatever. Cheers John
