Propeller Professional Development Board Rev. B (PPDB)
The Propeller Professional Development Board is a collector’s item now, no longer available from Parallax. In very good condition. This was from my bench collection which I must, sadly, part with.
This is the Blue Rev. B model. I do have a few of the original Gray Rev. A model as well. Please see the description below for complete product details.
Scribbler Robot w/Pen Lifter (S1)
The original Scribbler Robot. Now a collector’s item. This robot was the original unit used for the Pen Lifter modification I posted in Savage///Circuits TV Episode 9. I have just this one unit which hasn’t been operated since the video. See description below for complete product details.
