Interestingly, I was thinking the same thing. Although I wouldn't go as dense as an FPGA, I wouldn't do wire-wrap either. I was thinking of reducing it to a small VME enclosure with each of the major functional boards on a single VME board. Somewhere he must have the schematics such that you can grind it through an PCB/CAD + autorouter and come up with four VME boards while preserving the individual TTLs. It still gives you the feel of "old" but much easier for people to build. I saw a Java-based DSKY simulator, so I would definitely want to add a realistic DSKY enclosure. Radar and landing data could be emulated by another computer, feeding the output of one like a tape into the AGC. Neat project.

Also I would think the project done on a single small board with an fpga would be a better way to do it, brought out to the DSKY, or built into it. I was wondering what the annunciators, and servo outputs were hooked to. If this guy is not running the full colossus, then there won't be a problem when the program tries to gimble the descent engine, or is trying to track the radar in high, low or auto mode. very impressive though.
