   Actually, IBM did not supply a TTL-monitor for CGA until 1983 (the 5153). So in the early days, using the composite output (which is standard on IBM CGA cards) would be the easiest way to get CGA output to a screen in 1981.

   That is correct. All you need is an IBM 5150 with an IBM CGA card and 640KB of memory. The 640KB of memory may have been a very expensive option in 1981, but not impossible. Most parts of the demo don't need nearly that much memory any

   Oh nevermind, I thought you were referring to the intro screen of the demo... but there is something about Z80 in the article.

   Not sure why you are referring to the Z80? We compare against C64, which uses a 6510 (6502-derivative), not a Z80.

   We used a real PC obviously (my machine), and a capture device plugged into the NTSC composite output of the CGA card.
