Places to Eat in Maynard

This document is a compilation of diverse materials. The first page presents a map titled "Places to Eat in Maynard," illustrating various locations such as restaurants (French Restaurant, Pizza House, Tutto's, Russo's, Mister Takeout, Pizza Place), parking areas (Municipal Parking, DEC Parking for Training), and other landmarks (Powder Mill) in relation to several streets and routes (Rt. 27, Rt. 62, Summer St., Nason St., Walnut St., Thompson St., Hill Side St.).

The subsequent pages consist of a series of "PDP-9 Maintenance Homework Sheets" (numbered 1, 2, 3, 4, 6, and 7, along with an unnumbered PDP-9/9L Homework sheet) and their corresponding answer sheets. These homework sheets feature multiple questions designed to test knowledge of PDP-9 computer architecture and maintenance, covering topics such as:

• Instruction coding and decoding (DZM, LAC, TAD, LAW, CLA, JMS, AND).
• Memory Reference instructions and program sequencing (JMP, SAD, ISZ, JMS, CAL).
• Register contents and states (AR, PC, MB, MA, AC, Link) after various operations or program executions.
• Digital logic and circuit behavior, including inputs, outputs, delays, flip-flops (R111, B310, SAO F/F, SM flip flop, Digit Write Sink), and logical expressions.
• Memory operations, including address locations, cycle timing, access conditions, and effects of flip-flop failures.
• Program execution analysis, involving tracing code, calculating results (e.g., ADD overflow, end-around carry, octal results), and understanding instruction counts.
• Console operations and their effects on program execution and display.
