Hi, I'm clearing some space in the attic so have various PDP systems available in the UK. In the main these are the desk side style case (can be rackmounted) with 11/83, or similar. All feature a 5.25" hard-disk and floppy (dual DEC style) and one or more serial connections. These are nice systems to use, a bit quieter than UNIBUS :). I also have lots of QBUS cards, memory, etc and CPU boards including some more recent (faster) Mentec boards (M100, etc) with on board RAM, FPU and serial ports. Email if interested. These systems are available in either Bucks (near London) or Yorkshire. Thanks
