YAPDP (Yet Another PDP). Indeed here is another. Its a PDP11/73. It is a QBUS based system. The 11/73 came out in the early 1980s. This one spent its working life running custom software and a multi-user OS called TSX-Plus at a local pharmacy. TSX-Plus actually ran on top of RT-11. Sort of like the early versions of Windows using DOS to boot. And this PDP 11 actually boots. It is running RT11. It has an RQDX2 drive controller, KDJ11 processor board, DEC memory, serial ports and Ethernet. It is in a BA23 case with the proper rack mount hardware. No games are loaded at the moment. I guess I could go to my own website – RT11 Games at Saracom and get them. Anyway, here is some pics and Easter eggs too. And a picture of the nifty RX50 5.25 inch diskette drive. Space of two diskette drives but used one spindle motor. You put the bottom diskette in upside down. I also assigned the drive letters so it would mimic MS-DOS letters. I guess I was bored that day.
