Good points |
Easily portable. |
Bad points |
There was no provision for external program storage, not even by using an audio cassette recorder as employed by most other home computers of the time. |
How successful? |
The lack of any means of storing or loading a program meant the only way to enter programs was to type them in on the small keyboard. This was a serious disadvantage of the CC-40 and the likely reason it only sold in small numbers, despite its appealing design. |
Comments |
There was going to be a TI CC-40+ which would be the same as the CC-40 but with connections for a standard cassette recorder. Unfortunately in March 1984 Texas Instruments decided to withdraw from the computer market and the CC-40+ never appeared. |
