Project Aries. Z80 Cross Assembler and Linker User's Manual.

The Z80 Cross Assembler described by this document is a Zilog-standard cross assembler written in PASCAL. It supports all the Zilog-standard mnemonics, but its pseudo-ops are unique to this assembler (to some extent). This assembler produces relocatable code which may be later linked and loaded by its companion linking loader. This cross assembler was customized for application with the ARIAN II operating system. It is designed to be run on a CDC 6000 or CYBER class machine. The intended operating environment is in a timesharing mode on the host computer with a microcomputer linked to the host for communications and, specifically, downloading. (Author)
