After recording and checking a program cassette, you can
break out the tabs at the top of the cassette to prevent
accidental erasure. In the event you wish to record on a
cassette after you have broken out the tabs, you can do so
simply by pasting tape over the tab holes. You can record and
keep your own cassette software library starting with the game
programs in Appendix D. Cassette recording or playback
should require 5 + 2.5N seconds. N is the number of pages
recorded on tape. Recording or loading the entire 2048-byte
RAM (8 pages) will require less than 30 seconds. Ile next
section describes how you can design your own programs
using a unique easy-to-learn programming language called
CHIP-8.
