[cctalk] PiDP 8/I space wars on PI hdmi screen

I have a PiDP-8/I with a VT-220 connected via USB to RS-232 and an HDMI display. How can I get the Space Wars Program (boot IF=4) to run on the HDMI display using the VT-220 keyboard for the controls? I have cross-posted this to the PIDP-8 google group as well. Thank you.
