I apologize for this being my first post, I believe that this the right place where this gear will be appreciated.
Located in SF Bay area, I have accumulated a large collection of Atari hardware (520 to Stacy era) with its related peripheralia. The equipment was mostly used for music production and thus includes related MIDI software such as Midisoft and Dr. T's. I have yet to evaluate its current market price, but I will entertain reasonable offers.
Atari Stacy 4, in beautiful condition. Yes, it works, boots, and spins floppies:
