Playing Czorian Siege on the IBM PC
21The following is footage of Czorian Siege, produced for the IBM PC by Computer Applications Limited in 1983. It is not a complete playthrough, but rather just enough gameplay to serve as a reference for how the game performs on the original hardware it was developed for.
This footage was recorded from an IBM PC (8088 CPU running at 4.77MHz) with a ("new-style") CGA card. The audio was tapped from the PC speaker and the video was recorded from the CGA composite output. The result was post-processed from 30i to 60p; all source frames are intact.
Personal notes: This game, coupled with Dunzhin, is one of the first two games to produce speech on the IBM PC. They predate Castle Wolfenstein on the PC by at least a year.
If the game seems like it aligns to an 80x25 grid in graphics mode, you're correct -- the exact same game is playable on a monochrome screen using 80x25 text characters. If you boot it on a dual-monitor system, it asks you which version you want to play.
