All, I also have a 90s air cooled mainframe. Sadly I have all the hardware but no Bus and Tag cabling to go with it. I'd like to fire it up, but without the ability to cable it that's a remote pipe dream. I warn anyone taking one of these on to make sure they save the cabling from the copper scrappers as well. ESCON is still easy enough to get. Bus and tag has so far eluded me so I believe it must be getting thin on the ground. If anyone does know of a UK/Western Europe source, please let me know about it! Thanks, Colin Eby
