**********MAP SUMMARY**********
Maintenance Concepts for Type B Adapter Failure
This MAP is entered from Chapter 2, Step 4, Figure 2-3 (failure
code to card replacement). After cards that can cause Devise
Adapter Type B failure code 1000 were replaced this MAP is used
to isolate a failing 3277 display or printer that can also cause this
failure code. First the device adapter IML tests are run without
testing the attached display or printer and then the attached
devices are tested for readiness. The first to be found ready is
used for additional device testing, if no device is ready the
remaining device tests are bypassed. NOTE: the same IML
testing is performed when attached device is a printer or display.
CAUTION: Before removing cards or cables switch power off.
Is the IML test failing with error code 10007
