<b) The Intellec MCS8i panel can access not only the 64K address space of
<the 8080 but also the 256 I/O ports. If you flip the right switch you can
<use the top 8 switches to select a port and output data to it using the
<bottom 8 switches. All this is done in hardware (the frontpanel simulates
<an 8080 I/O cycle) without the use of the 8080.

It was a neat hack too!
