PDP 11/70s For Sale

<Which series is most compact (sized for desktop or tower style) pdp An 11/53 thats a 11/23 cpu in a BA23 box. About 6Wx28Hx30D and an easy 110v outlet. With a RD52(30mb) and a RX50 floppy you can run most any PDP11 OS including unix (starting with 2.9 or 2.11). The other choice is a BA123 (end table) with a 11/23 or 11/73 in it. Fast and plenty of disk drives, not to hard on power(110V 600Wmax). If you want something really low power, a PRO350 (or 380) that's a PDP11 or a PDT11/150 (tiny and very low power, less than bigger PCs). PDP-11 line run from the really big like the 11/70 down to a single board (falcon card T-11 cpu, 2 serial, Parallel, 2kw ram, rom, one dual card!). So having a PDP-11 os some sort is very possible and they are all for the most part PDP-11s differing mostly in speed, IO and maximum memory. Allison
