Welcome to the nanoPEB & CF7+ Website!

nanoPEB and CF7+ were designed to bring the full experience of the TI-99/4a home computer into the 21st century and yet be affordable. This site offers the support programs and manuals needed to run either. As time progresses, articles and a FAQ will be added to help get the most out of both.
