Finally got around to imaging the +/- 80 floppies that came with my ACI-90 Pascal Microengine system. Disks of general interest can be downloaded on ftp://ftp.dreesen.ch/WD9000/MicroEngine.zip These are mostly variants of the OS and a set of system selftests. Image SYSTEM/OS_F0_SingleDensity.IMD might be of particular interest as that is a single-density OS-disk, might be needed for those with very early systems. All others images are for double-density systems. Sorry for the lack of documentation, I don have anymore than this, and have yet to check the contents... As a sidenote, all BASF disks were unproblematic, unlike the ControlData and noname parts that were also in the mix. Jos
