The DEC DF02 (300 Baud) and DF03 (300/1200 Baud) modems appear to be singularly lacking in online documentation. In the case of the DF03 those would be: EK-ODF03-IP - DF03 Illustrated Parts Breakdown EK-ODF03-PS - DF03 Modem Pocket Service Guide EK-ODF03-UG - DF03 Modem Users Guide Similarly for the DF02. (Note that the actual designations may use a zero rather than a capital letter O in the 4th position; references are inconsistent.) Does anyone have access to these documents? The only, and only slightly, useful technical documentation I've found are within the KC780 documentation (EK-KC780-TM-007_Jul84.pdf), which illustrates the required settings of the two pairs of DIP switches (or jumpers) on each of the two DF02/03 internal modules but doesn't define any of those settings. The functionality of the front panel push-button switches is not described either. Leads, experience, etc. appreciated, thank you, paul
