Can anyone out there tell me where to find interface specs for the printer port on a DMF? I need things like timings, pin designations & definitions, etc. John Sherwood Dalhousie University Halifax, Nova Scotia BITNET: SHERWOOD@DAL

John, The DMF32 printer port pinout is described in the most recent version of the _DMF32_User's_Guide_, EK-DMF32-UG-003 (or later), Appendix C. Earlier versions have errors in the pinout. (They erroneously claim that "strobe" is available on pin 37, while it is actually on pin 8.) Unfortunately, the DMF32 manual doesn't include signal timings. The signals are "Data Products" compatible: polarity is reversed with respect to "Centronix" signals. Dataproducts' manual _B-Series_Line_Printers_Models_B300/B600_Maintenance_Guide_, publication number 255137, describes the signal timings on page 3-19, and the pinout for the connector at the printer is shown on page 2-14. Your local DEC Field Service office should have a copy of this manual, since DEC resold those printers as LP25 and LP26. Alternatively, our copy of the manual claims it can be ordered from Dataproducts Corporation 21300 Roscoe Boulevard Canoga Park, CA 91304 (213) 887-8033 I hope this helps, Selden E.
