Equipment for the Home Office

I am using a programmable calculator my first piece of equipment for my small office/ home office.  It uses a dialect of the BASIC language for programming.  It has function and menu keys that lend itself to the application of everyday math (& physics) in the home office.  Storage of programs and data is non-volatile and therefore it is a great addition to the home office library.  It can be utilized indoors and outside as well.  The design of the programmable calculator allows it to be an important component in the development of a portable home office.  Operating costs for the programmable calculator are about the cost of 1 exchange of triple A batteries per year (approximately $5) and therefore it serves as an economical component in the development of a portable-electronic home office.  I am currently involved in a study of energy and equity considerations in the design of SOHO (small office/home office  outdoor summer showrooms .  I am developing a program named CG (calculator graphics) using the drawing features of the programmable calculator.  Programmable calculators can be linked to one another to share data and programs well as to other computing equipment such as a netbook or a mini desktop computer.  There is even a video display unit for connecting the programmable calculator to a TV for educational and entertainment applications.  The programmable calculator serves as an all-in-one asset for the home office.
