The Vintage Amstrad CPC 464 computer is the first 8 -bit home computer produced by Amstrad, an English company. It was in production from 1984 to 1990. It is equipped with ZIOLO ZIOLO ZOLOGE and supports the CP/m operating system.

La sigla CPC sta per "Colour Personal Computer". Nonostante ciò, il computer Amstrad CPC 464 nella mia collezione ha il monitor Amstrad GT 65, che è monocromatico. Ho deciso di acquistarlo ad inizio 2022, così, ho partecipato ad un'asta su eBay. Gli offerenti erano pochi e sono riuscito ad accaparrarmelo a buon prezzo.
Unfortunately, during transport, the monitor suffered slight damage, due to the packaging made badly. The seller partially reimbursed me, making the purchase of this vintage computer even more convenient.

Starting screen of the AMSTRAD CPC464
The vintage computer start screen is with yellow writings on a blue background. With the Amstrad GT65 monitor, being monochromatic, you can see with green writings on the background ... green!

CP/M operating system
The Amstrad CPC 464 supports the CP/M version 2.2 operating system. In order to load it, you need to have the Floppy Disk Drive connected to the computer, with the CP/m dischet. To start the CP/M, use a specific Amsdos command:
|CPM
Amsdos (abbreviation of Amstrad Disk Operating System) is an operating system integrated in the ROM of the AMSTRAD CPC464, which allows the computer to manage the floppy disk drive.
