According to the artist, the small, colorful keys gave "a somewhat playful air to the computer", as it was for domestic use, thus needing to "harmonize with even decorative objects".

[11] Although the design of the CP 400 is attributed to the aforementioned Italian artist, its notable similarity with the Timex Sinclair 2068, also launched at the end of 1983 in the United States, remains unexplained.

[9] Due to a design error, there could be problems with the unit overheating.The CP 400 COLOR II, launched at the end of 1985, offered an external power supply, better keyboard (with four extra keys: CTRL, PA1, PA2 and PA3) and 64KB of RAM.

Prológica itself has launched dozens of game and utility titles, including: Attack, Crash, Bingo, Castle, Checkers, Dinosaurs, Editor, Climbing, Skiing, Graphics, Islands, Invaders, Labyrinth, Meteor, Nebula, Pegacome, Pipoca, Saltimbanco, Tennis, Horror, Target Shooting and Chess.

In fact, it was "Disk Extended Color BASIC" ( DECB or RSDOS) from Tandy Radio Shack, renamed and, most likely, used unlimitedly without prior license or knowledge from the American company (a practice that became "very common" in Brazil at the time of the Market Reserve and which possibly contributed to the end of Prológica, when it was sued for piracy by Microsoft).

Even Editele - a company belonging to the Prológica group - specializing in the publication of technical books in the IT area, made only a single title available: "Indo Além com o CP 400 Color", by Paulo Addair (1985),[21] which presented lists of programs aimed at exploring more advanced features of the equipment.

Very few titles were published: As a result, software houses such as Micromaq, Plansoft, Peek & Poke, Softkristian and Engesoft, among others, reproduced and sold foreign works, especially by North American authors, given the success of the TRS-80 Color line in that country and the greed for information among Brazilian users.

Sporadically, however, it was possible to find listings in Color BASIC in generic computer magazines, especially in the then highly respected Micro Sistemas .

On the other hand, the magazine Geração Prológica, published by Editele, had a brief life: just 18 issues; materials and programs related to CP 400 occur only between numbers 9 and 17.

Its direct competitor was the TK-2000, from Microdigital Eletrônica, with similar sound and graphic abilities, as national clones of the Apple IIe were considerably more expensive.

This situation would soon change, initially with the launch of the TK-90X, a clone of the ZX-Spectrum introduced by Microdigital in June 1985, and mainly with the beginning of sales of MSX standard micros by Gradiente and Epcom/Sharp in December 1985.
