It's by Acroatix. "The Most Precious Commodity." It's big, but it is well designed. I think with REX in the picture it makes a lot more sense since you can devote a "virtual model T" instance to it and quickly swap it in as necessary.
It's in the M100SIG archive. I should have a .CO file around somewhere. Otherwise I found I needed TS-DOS in "DOS" mode to load if via HXFER format since the archive has text encoded rather than binary files. At the time I was using DLPilot, but it should load the same via LaddieAlpha. -- John.
