I think it was an episode of computer chronicles (via archive.org) I was watching that was showing off a new cd based encyclopedia. Bragging about the capacity and amount of cds and it could be used on the $800 cd player for the ibm pc. I think the episode of dr who representing our history with "the ipod" (a jukebox) is pretty likely though. Technically 50 years from right now would be quad core processors and lcd flat panels. I'd almost dare to say an fps gaming rig might represent 2012s home computer. -----Original Message----- From: Eric Smith <eric at brouhaha.com> Sender: cctalk-bounces at classiccmp.orgDate: Fri, 04 Jan 2013 23:02:27 To: General Discussion On-Topic and Off-Topic Posts<cctalk at classiccmp.org> Reply-To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: Re: NASA computers circa 1969 Tim Shoppa wrote: I lost track of the thread somehow, so I'm not sure *what* somebody here did. I have some CM100 players but no CM153 cards. I think the player is equivalent to the DEC RRD50, so it should also work with a KRQ50 (M7552) for a Qbus system, but I don't have one of those either. Some years back I reverse-engineered two versions of the CM100 firmware (8051). The interface uses DA15 connectors with four EIA-422 differential pairs. If they had made the interface only a *tiny* bit different, they could have supported eight CM100 drives on a single host adapter. The CM110 is the same drive with an additional board that interfaces it to SCSI, but I've never gotten my hands on one. Eric
