tto terminal output
clk 100Hz and TODR clock
13-Jan-12 MP Normalized the saved format of the TODR persistent
file so that it may be moved around from one platform
to another along with other simulator state files
(disk & tape images, save/restore files, etc.)
28-Sep-11 MP Generalized setting TODR for all OSes.
Unbound the TODR value from the 100hz clock tick
interrupt. TODR now behaves like the original
