Time of day does not print correctly under MCP control

[Google Code Exporter]

Time of day (e.g., in response to a WT SPO command) frequently does not format 
properly, e.g., TIME IS 2L3M.

As observed thus far, the letters in the time are always in the range J-R, 
which may indicate that the internal time counter from which the time is being 
formatted (XCLOCK) has gone negative, as character mode in the processor 
converts negative binary numbers to characters with a "J-sign" in the low-order 
position. Thus, since the hours and minutes fields of the time are formatted 
separately, 2L3M could indicate a time of -2334.

This appears to have been a misunderstanding of how MCP initialization is 
supposed to work. When option 40 (TYPE TIME) or 41 (TYPE DATE) is set, MCP 
initialization does not complete until a TR and/or DT command is entered, as 
appropriate. Until that time, XCLOCK is set to a negative value, and most SPO 
commands are inhibited. This was never a problem.
