Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides an integrated circuit component (hereinafter referred to as "engine C") that can be installed and removed from a computer main body and replaced.
This invention relates to a computer that can be made to perform operations according to the situation. For details, see RO that computer users can use for video games, business, education, etc.
This relates to a computer that can use various software and expand its memory capacity by replacing M or RAM.

Conventional configurations and their problems In recent years, computers, especially personal computers, are equipped with only the basic functions on the computer itself, and the application software required by the user is stored in the form of floppy disks, cassette tapes, ROM cartridges, etc. There was much to supply. Among these, special [.

-Currently, many end computers use ROM cartridges, which are easy to use even for beginners and are less likely to cause incorrect operation.

Because of the functionality of the computer, I other than ROM
Cartridges for C (for example, RAM for expanding memory capacity) or signal conversion circuits for peripheral devices (for example, interface circuits for printers and floppy disks) are also available.

Conventionally, there have been two types of cartridges for integrated circuit components (hereinafter referred to as 1-ICJ) such as ROM or RAM as described below.

In the first form, the IC is handled independently, and a connector corresponding to the shape of the IC to be used is provided in a part of the main body, and the user connects the IC as required to the connector. It is something. This first type of IC cartridge is generally called an IC pack (for example, a ROM pack). Therefore, herein, a device that handles an IC alone or in combination with a simple holding means will be referred to as an IC pack. The method for replacing ICs using such an IC pack is that only one type of IC can be connected to one connector (C). ROM,
This has the disadvantage that ROMs having the same memory capacity but different program write start addresses cannot be used by connecting them to the same connector. Furthermore, when handling the K1C bag, it was easy to touch the IC terminals with one's hands, and there was a risk of deforming the IC terminals or destroying the IC due to static electricity.

In the second form, the IC is attached to a circuit board such as a printed wiring board and is used by being built into a plastic ring case or the like. Since this type of cartridge is generally called an IC cartridge in a narrow sense, hereafter only this second type of cartridge will be referred to as an IC cartridge.
This will be distinguished from the first type of IC pack. In the case of the second type of IC cartridge, if a printed wiring board with a circuit according to the IC specifications is prepared, an IC cartridge with different specifications can be used.
It is also possible to connect cartridges for signal conversion circuits (for example, printer interface circuits, etc.) with other devices that incorporate multiple integrated circuits (ICs).
The problem is that the size of the cartridge is large, the number of types of printed wiring boards that must be prepared is large, and the product price is extremely high.

Purpose of the Invention The present invention solves the above-mentioned conventional problems, and
It is easy to handle without touching the IC directly, and it can handle ICs with different specifications such as memory capacity and program writing start address.
An object of the present invention is to provide a computer that can be used by attaching and detaching a pack.
