The ASCII Translater Codes
April 14, 2002
Three devices were designed to help visualize the processes
of our CAPC computer. You can see translaters in the image
below. We were able to identify SENDER, VALUE, LOADER1, LOADER2,
and MACHINE STATE. Their current values are displayed in the
translater. The coloured bar on the right side lights up to
show the current signal of the fetch/execute cycle. Whenever
something is read from RAM, the READRAM unit lights up. In
this example, PC is sending its value to MAR and X during
the fetch cycle. The table below shows the ASCII codes utilized
in the translaters.
