Using tu56 on the PiDP-8
************************

You need to run full Raspbian, not Raspbian lite, to display tu56 on the screen.

Use the PDP-8 DECtape driver:

  cd 
  cd Tu56/simh/pdp8_dectape_driver
  chmod +x install
  ./install

Building a new version of SimH with install will take a while, especially on slower Raspberry Pi
models. The new DT driver generates a status byte in /tmp/tu56status, which can be used by tu56.

Instructions for using DECtape provided by Warren Young:

  MOUNTING a DECtape image
  ctrl-e
  Simulation stopped, PC: 01210 (JMP 1207)
  sim> att dt media/os8/al-4691c-sa-os8-v3d-1.1978.tu56
  DT0: 12b format, buffering file in memory

  BOOTING FROM DECtape
  To reboot the PiDP-8 to DECtape:
  set IF field to octal 3
  then toggle Sing_Step, then set IF switches back to 0
