Yet another MBHP SID synth, this beast of a project contains four SID chips that can be controlled through the full Midibox SID control surface. Built into a breadbox C64, this project was also pretty much about testing how to use other parts besides the plain enclosure. If you’re planning to build one, the posts for this project might give some ideas about how huge a project you’re about to start working on.. ;) Completed in 2005.
