Univac Document Archive: 1106/1108 Assembler Programmer's Reference Added

I have added the following document to the Software section of the Univac Document Archive. This is a PDF of a scanned paper document in my collection. This document was published in 1969 (two earlier editions date from 1966 and 1967). This describes the “classic” assembler, which was derived from the SLEUTH II assembler for the Univac 1107. As of the publication of this manual, the assembler supported only FIELDATA character code and six bit characters; it would later be extended to support ASCII code and nine bit (quarter word) character representation. In the 1970s, the new Meta-Assembler developed by Derek A. Zave became the standard assembler for 1100 series systems, although the original assembler remained available and many people continued to use it.
