In 1983 I and Fabio Cunha designed a Logo computer with the 6809 processor: http://www.merlintec.com/lsi/pegasus.html http://www.merlintec.com/lsi/pegasus.html The project evolved into a more advanced 68000 based Smalltalk computer, but I regretted not finishing and releasing the original machine as years later I saw what schools in Brazil were doing with MSX Logo and such. The big mistake in the design was using the same chipset as the TRS-80 Color Computer which had a bunch of needless text and low resolution modes but no nice high resolutions ones.
