This is a fairly recent addition to the website, so please excuse me while I add more stuff and organise, sort and tidy up what is here. The pages will likely mostly concentrate on the Control Lab and RCX given my interest is in older computer control.

Lego Pages

Some ramblings on motors and motor controllers. This is a work in progress.

Information About Programmable Hardware.

Control Lab LOGO Reference – I extracted the LOGO reference manual from the in-application help system in the Macintosh version of Control Lab 1.0. The contents are available here.
