Hi Brian, for a moment I thought it was an SSP, but the SSP would have some 8 inch floppy drives. IIRC the SSP (System Support Processor?) was needed to startup the 1100 series before you could mount a tape with a sysgen'ed bootable system. Unisus (Sperry) machines required a sysgen for every disk or tape drive or whatever. Very unlike PDP-11's which recognize what options are connected to the bus. But then again, an 1100 is quite a different league, as is EXEC, the Operating System. This is all very vague to me. Anybody, please feel free to correct me. So, I am not sure Brian. The SSP's I ever saw where alike, but then different :~) my 2c, - Henk, PA8PDP. -----Original Message----- From: cctalk-bounces at classiccmp.org To: cctalk at classiccmp.org Sent: 11-7-2005 20:27 Subject: univac something or other Anyone know what this is? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7335084988 It appears too be a CRT terminal of some sort, but the box is pretty large, which is odd. Key to disk maybe? From the styling it looks like late 70's, early 80's? This is the item's second time up. I've written to the seller twice for more info but he's not bothered to respond. I'm curious to know if anyone recognizes this. Google didn't turn anything up. Brian
