The Compact Computer 40 (or CC-40 as it is often called) is a small computer that is quite big on power. The built-in BASIC is quite extensive, rivaling its bigger brothers and sisters from the time period. Like other portable machines of the time, the CC-40 uses static RAM which means that all the programs and data that are in it survive for months, even when the power is turned off. The unit can run on 4 AA batteries or with an optional AC adapter.

The CC-40 promised integration to a Wafertape digital tape drive for mass storage but the unit was never available for mass production due to reliability problems. An RS-232 and printer interface were available (let us know if you have these, because we don't).

The system allowed for expansion via a cartridge slot that could contain either a solid-state program (we have the Finance cartridge for example) or you could also buy additional RAM expansion. The static memory was called Constant Memory by TI although this was simply a trade name for something many other companies used.

The screen shows 31 characters on its 5X8 dot matrix LCD screen although the system treats "lines" as 80 columns, scrolling to let you see more. There is only one working line at a time although there are various indicators permanently on the display that light up under certain conditions (ERROR for example).

The systems uses a TI TMS 70C20 processor running at 2.50 MHz and has a 34KB ROM.
