Not sure I understand this sentence but there were lots of Amiga models.
A1000 - The first Amiga. I have one of these and the inside of the case is signed by all of the chip designers. It had 256kb memory with an expansion to 512kb and a separate keyboard to the base unit.
A500 - The one that made it popular. I also have one of these along with the addon CD drive and various peripherals.
A1500/A2000 - Actually the same machine but they were marketted differently. The A1500 was usually bundled with games and the A2000 bundled with application software.
A3000 - A real beast with a 68030 processor. Great for 3D rendering.
A500+ - The updated A500 with 1mb of memory IIRC and Kickstart 2.0
CDTV - Looked like a HIFI CD player but with an Amiga under the hood. Expensive for its time and didn't sell well. No floppy drive and you had to buy a keyboard separately if you wanted one.
A600 - Great little machine but no keypad which made Deluxe Paint tricky to use. Came with or without an internal hard disk and had a PCMCIA slot. Kickstart 3 I think.
A1200 - Released at the same time as the A600 but with a numeric keypad and a 68020 CPU. Again, came with or without a hard disk and had a PCMCIA slot. Kickstart 3 I think.
A4000 - The most powerful of the mass produced Amiga's with a 68040 CPU. Superb machine.
CD32 - Their attempt at a games only console. No keyboard or floppy drive, just joypads and a CD drive built in. It was basically an A1200 under the hood but didn't sell too well.
These are all the ones I worked on (repaired or upgraded). I don't think I missed any out. Great days.
