ZLPL - LP25/26/07 line printer test ABSTRACT: This program verifies proper operation of the LP25, LP26 or LP07 line printer and its associated M7258 control unit. HARDWARE REQUIREMENTS: PDP-11 CPU, 16 KW memory. A KW11-L line time clock or KW11-P programmable real time clock is necessary for measuring the time interval from which printing speed is determined. SOFTWARE: This diagnostic has been written for use with the diagnostic runtime services (supervisor). OPERATING PROCEDURES: This diagnostic has been written for use with the diagnostic runtime services (supervisor). For a complete description of the runtime services refer to the XXDP+ User's Manual. RUN TIME: 1 pass takes approximately 5 min. NOTES: Quick startup procedure: Type ''R ZLPL??'' Type ''start'' Answer the ''CHANGE HW'' question with ''YES'' Answer all hardware questions Answer the ''CHANGE SW'' question with ''NO'' Individual tests: test 1 interface logic test 2 ready line interlocks test 3 forms length selection test 4 printing speed test 5 data transfer paths test 6 printable characters test 7 non-printable characters test 8 band pattern test 9 spurious hammer firing test 10 print control test 11 multiple line advance tets 12 character alignment Example: ''START/TESTS:1:2:6-9:11
