Included are the RAM based drivers and a copy of the ROM (ROM courtesy of SimonSideburns on the StarDot forum).
The original A4 plotter drivers disc is still MIA. The included one is one that has been partly reconstructed by the archive.
The ROM driver appears to be very scarce.
The manual in the download covers both the RAM-based drivers and the ROM drivers and has been re-typeset by the Archive from a similar digital copy downloaded from the internet.
