<I do. I always wanted to turn it into a semi-portable UNIX machine < <> It's a VT100 with a 4-slot Q-bus backplane inside (!). Actually it was 3 quad wide or 6 AB slots. <Some even had TU-58's in the front. Never. that was a PDT11/130 that was demoted to a Vt100 then had one of two possible backplanes installed. The 11/130 TU58 would ahve the board swaped out was it was the ONLY parallel version and the rest were serial. <> There's a paddleboard in <> the STP slot that links to 2 ports on a DLV11-J (4-port RS232) card in <> the backplane. < <*That* I don't have. :-( Not required just means different cables. The STP card interconneccted the VT100 but you could to that with a cable from the VT100 DB25 to a MXV11 or DLV11j just as easily. <> The VT100 becomes the console for whatever processor you <> stick in the Q-bus, while the connector on the back is a normal serial <> port, also on the Q-bus system... If you have that STP card. Otherwise it's just a console and you use a modem program to (VTcom, Vterm). <For compact systems, the MXV-11 also works with the paddle card - two port <and some memory. MXV11 x2 gets you 32kW, 4 serial ports and boot roms plus a cpu card is a system. The only other card would be a RXV11 or RXV21 (or similar) for a floppy. The TU58 if you have one of the cases with it uses a serial port and the MXV11s (x2) will certainly provide that. Another config is KDF11A (11/23 m8186), one or two 256k cards (q22), DLV11J (4 serial ports), M8212 (boot) and a RXV21 (or RQDX3). With Qbus 11s you can slice and dice it a lot of ways. Allison
