A metà anni '80 il CEO e fondatore di commodore Jack Tramiel lasciò per ATARI portando con sé molti progettisti ed ingegneri; la compagnia si trovò così improvvisamente senza risorse per industrializzare il proprio primo PC a 16 bit. Allo stesso tempo, per fortuna, alcuni degli originari progettisti ATARI avevano fondato una compagnia chiamata AMIGA; Commodore, orfana del suo fondatore, vide l'opportunità di inglobare AMIGA al fine di dare vita al primo COMMODORE a 16 bit. Il risultato fu il lancio nel 1985 dell'AMIGA 1000. Poco più tardi nel 1987 venne introdotta l'amiga 500, con un istantaneo successo di vendite. La A500 condivideva l'architettura della A1000 e fu commercializzata fino al 1992. Presentava un hardware di assoluta avanguardia; processore motorola 68000 a 7,19 MHz con 512 Kb di ram, lettore floppy disk integrato nel case con tastiera e mouse a 2 pulsanti. Si collegava alla tv mediante uscita A/V era dotato di sistema operativo denominato AmigaOS in parte residente in rom. Le prestazioni incredibili per il periodo (altri impiegarono almeno 5 anni per raggiungere il medesimo livello) si devono alla divisione dei compiti tra sottosistemi di cui la CPU 68000 fa da supervisore: i chip denominati DENISE (memory controller) Paula (Audio controller) e Agnus (video controller). Infatti il motorola 68000, pur consentendo un clock potenzialmente 7 volte più veloce del MOS 6502 presente nel C64, risulta meno efficiente del MOS il quale riesce ad eseguire molte operazioni in un solo ciclo di clock; così l'incremento di prestazioni si riduce a circa 3x. La vera differenza risiede proprio nell'uso di coprocessori. Tali caratteristiche avanzate di grafica e suono ne fecero una piattaforma molto popolare ed indimenticabile per i videogiochi. Un'ultima menzione merita l'interfaccia grafica workbench che già nel 1985 offriva un vero ambiente multitask di tipo preemptive.Un grazie all'amico Luca per aver messo a disposizione questo splendido cimelio.

But it is in part definitely so. In the days of the basic, the dos, the assembler or the cp/m he 'turned' with very little ram and there were nice programs to do everything. It wasn't a graphic environment, but it wasn't a tragedy. :-D

Hello Valerio, you can find the c64 in my gallery. Unforgettable.
I am pleased to share many memories and with a lot of participation.

Dear Loris, however, I appreciate your passage, with the amiga ending in my opinion the most beautiful period of a certain computer science. I remember with great pleasure that period. ;-)

Hello Alejandro, the amiga series was the last success of commodore and the beginning of the decline of this historic brand that some all those who lived that period in person remember

This period of computer science is completely in the dark, a big mistake I made. I'm an accountant I worked for 4 years in the bank in Argentina, I snubbed computer science and the same mistake I made with the arrival of digital in photography. Unfortunately I did not understand the changes and in a way I paid dearly. Thank you also for this information. A warm greeting.

Alejandro I don't know if it was a mistake. It was a good time but home computers soon ended and replaced by compatible ibm clones, the era of ms-dos and then windows began. It lost a little bit that push to the "homey" programming started with the basic. When you turned on the computer, you had to do something :-D
The merit of commodore was to introduce in the homes computers at "low" cost, to trigger curiosity about machines and operation if you wanted to deepen. I do not hide from you that I also lost much of the initial interest and today I find much more satisfaction in other type of programming.

I got out of the time machine but now I'm going up and I'm going to take another ride

Compliments Giancarlo
