The .ent files in this directory is software in the entry
format used by Processor Technology CUTER. To load and run
the software:

./altairsim -x cuter-mits.hex < file.ent

This starts the Altair emulation, loads the CUTER OS into memory
and redirects the .ent file to the MITS SIO. Switch machine on
and flip RUN, the CUTER prompt > will be shown on the VDM monitor.

In the monitor window type SET I=1 (upper case is mandantory), so
that CUTER starts reading the software from the MITS SIO.
The .ent files inlude SET I=0 as last statement, so that input
is back from the SIO to the VDM.

To run the programs type EX <start address in hex>. The start address
of the programs is the first load address, usually but not always 0.
