The setups I have seen require a lot of square footage. You have printers, tape drives, and big DASD farms connecting to controllers and communications controllers and finally the mainframe which may itself be a complex consisting of more than one physical box. I have not seen a machine room that wasn't all raised floor. I don't know that a small setup exists with the bus and tag technology but that was years ago. The new stuff is smaller and also doesn't need raised floor. Seems like it's probably an either or situation. When you need raised floor you need a lot. When you don't, you don't. ------Original Message------ From: ben Sender: cctalk-bounces at classiccmp.org To: cctalk at classiccmp.org ReplyTo: General Discussion: On-Topic and Off-Topic Posts Subject: Re: wanted: raised flooring for cheap Sent: 7 Dec 2011 18:26 On 12/7/2011 11:10 AM, Vintage Coder wrote: The other problem with raised flooring is who's floor are you on? With a small system, could a raised island be built, with the computing equipment raised say a foot or so, with just false floor between the equipment. Ben.
