Yes. They were pretty much raw RGB data if I recall. They talked to an analog video monitor in TV or Laser Disc resolutions. The ones we had had two video cards. I think one was a Herc mono compatible for the DOS stuff. I think the one connected to the TGA was analog inputs with seperate sync. Until you activated the TARGA card, the screen was blank. I think in later versions we could load a graphic onto the video card for static display until you loaded the TARGA software. I don't recall the term micro-dots, but everything was anti-aliased. I was the technoid that connected the devices, made them all talk, and cobbled together software for moving the images. I also learned a lot about video production. I think their character cenerators were originally Sony MBC-55s. They then moved to Chimera or something similar. I just remember replacing the ROMs and software on these units all the time for upgrades.
