This software lets you control the Lego DACTA Interface B (8751) from
Classic Mac OS, from System 6 onwards.

You can write programs in the LOGO language and create your own user
interface. There are a number of UI elements you can use including
graphs, which can plot data from analogue sensors.

Download #1 - LEGO DACTA Control Lab 1.0 Mac floppies (Color + Black &
White), compressed in a StuffIt file.
Download #2 - LEGO DACTA Control Lab 1.0 Mac floppies (Color + Black &
White), in a more FTP friendly hqx and SEA format.

If you have a newer version (later than version 1.0) please upload it!
I've seen versions as new as 1.4 mentioned in a PDF online.

Note that the [RoboLab][1] software is also compatible with the
Interface B.

I believe that this software is based on [MicroWorlds][2] by LCSI.

Compatibility
Architecture: 68k

Macintosh Plus or newer I think. There is a colour and a black and
white version.
