Hello GDIY,
We are approaching the BBC LIM/2 as an "add-on" device devised to compliment Custom Tube Console specs. @ruffrecords
Before I get ahead of myself, we have to thank Heikki for suggesting the BBC LIM/2 as a build option for learning as well as providing all the specs, schematics and R&D papers linked here. The R&D paper in particular is a very informative and fun read.Given the documents shared are photocopied and we are sifting through details while searching online for more, If you find/have anything worthy of mention in regards to the BBC LIM/2 please let us know ad we will add it to this heading post. To get started I have cropped a few images to discuss.
