 == Introduction
 The **Stellar Dynamics SD-8516** represents a categoretroical reimagining of microprocessor architecture. This 16-bit CPU, implemented in AssemblyScript for the VC-3 computer system, delivers performance exceeding conventional silicon constraints through advanced cross-boundary resonance microcascades.
+The SD-8516 is intended to be an easy to learn architecture which remains era-authentic.
