The Basic Atom Pro is based upon the Renesas 3664 processor.  Basic Micro
wraps the 3664 processor with standard hardware port assignments, a BASIC
library and programming tools to provide the solution.  

Without hardware or BASIC library support for USB, adding USB is not so
easy.  It requires adding a device like a Cypress CY7C68001 USB Interface,
which only comes in surface mount packages.  It requires an added parallel
interface from the BASIC ATOM PRO, pins that we don't have, so a bridging
solution is needed, such as I2C to Parallel I/O.  The other option is an
integrated RS-232 to USB bridge, but why build something in that is
available off the shelf?

Clearly we should keep the RS-232 interface and keep any USB bridges or
interfaces external to the CVS.

For those without RS-232 ports, buying a 1999-2000 era Intel based laptop is
an inexpensive option.  These will run Windows 98 and have an RS-232 port.
I have one around just for that purpose, purchased for $75 from the local
school surplus store.
