Commented disassembly of the GI(tm) CTS256A-AL2(tm) Code-To-Speech Processor

The CTS256A-AL2 is an 8-bit microcomputer programmed to create text-to-allophone address sequences, in flexible and cost effective manner. It sources the SP0256A-AL2 which is a speech synthesizer whose output drives an audio amplifier to produce speech output.

Input of the CTS256A-AL2 is standard English ASCII characters, which makes connecting to a stand-alone terminal or any personal computer simple.
