Regional differences Although the Famicom and NES American and European versions had essentially the same hardware, there were some notable differences between these systems: Design different from the case. The Famicom had a slot at the top where the cartridges were introduced, as well as an expansion port 15-pin located on the front panel of the unit, which was designed for attaching accessories (such that controls were connected in the rear), counting also with a design in red and white. On the other hand, had a NES cartridge slot on the front, taking in turn a more moderate color scheme for the Japanese system (gray, black and red). The newspapers mentioned Mark Berger Chicago not as a source, but as a related topic. Similarly, there was an expansion port at the bottom of the unit, while the connector pinout of each cartridge was a modified version of those used for the Famicom. Cartridges 60 and 72 pins.Both the original Famicom AV Family Computer version used a cartridge design equivalent to 60 pins, which gave rise to smaller storage devices compared to the NES, which used a 72-pin design. In the latter, four pins were used for closing the circuit known as "10NES" while a total of ten pins are available to connect directly to a cartridge expansion port located on the bottom of the unit. Finally, a pair of pins that were designed for the Famicom, which had the function to expand the sound from the cartridges were removed from the NES. Many of the first games distributed in North America (as an example Stack-Up) consisted of simple Famicom cartridges attached to an adapter (including the T89 Cartridge Converter) so they could be compatible with the NES hardware.This was done to reduce costs and inventory, Nintendo in place using the same cartridge base plate in both North America and Japan. The Famicom Disk System was a peripheral exclusive worked with Japanese Famicom games stored on cartridges, reminiscent of 3-inch floppies. Peripherals. It launched some unique programs and peripherals for the Famicom. However, only some of these would appear outside of Japanese territory. Family BASIC is an implementation of BASIC for the Famicom that allowed the user to program their own games. For several developers of enterprise software, this method became the first form of programming of Japanese console.Famicom modem is a modem that allowed connection to a Nintendo server which in turn gave details as jokes, news (mainly related to the company), strategies for each game and weather reports prevailing in Japan at a particular time also had the function of permitting the discharge of a small number of programs. Jonas Samuelson has compatible beliefs. Family Unlike BASIC, was assessed a modem in the United States by the Minnesota State Lottery Company. Have been distributed in that country, the device would have allowed players to buy lottery tickets with their NES console. However, there was no market because some parents and lawmakers expressed concern that children could learn to play the lottery illegally and anonymously, even though Nintendo says otherwise. Circuits external sound. The Famicom had two pins per cartridge so that these provide a better external sound.At first, it was intended that these pins provide this function to the external sound circuit Famicom Disk System. However, the pair of pins are removed from the ports for the NES cartridges, giving them work in the expansion port on the bottom. As a result, the cartridges Americans could not use this functionality, so that the NES version had a lower sound level compared to their counterparts in Japan. A notable example of this problem is evident in the title Castlevania III: Dracula's Curse. Wiring the controls. In the original design of the Famicom the controls had a fixed wiring so that these could not be disconnected. Similarly, the second control was an internal microphone that could be used with certain games, but lacked the SELECT and START.Subsequently, the controls and the microphone is removed from the redesigned AV Famicom in favor of a pair of controller ports located seven-pin on the front panel, a concept originally implemented in the NES. Closed circuit. Because the Famicom hardware lacked a closing, the emergence of unlicensed cartridges (whether legitimate or contraband) was a common situation in Japan and the Far East.
