The first Amiga computer was the "Lorraine" by Amiga Corporation in 1984, developed using the Sage IV system. [1] It consisted of a stack of breadboarded circuit boards. Commodore International purchased the company and the prototype and released the first model, Amiga 1000 in 1985.
In the A3000 and A4000 series, Ramsey controls the on-board 32-bit Fast RAM, four banks of either 1 or 4 MiB, and provides address generation for Super DMAC. The SDMAC in the A3000/T provides DMA and bus interface for the integrated WD33C93A SCSI controller. Officially, SDMAC rev 02 requires a Ramsey 04, and SDMAC 04 a Ramsey 07 counterpart.
Amiga is a family of personal computers produced by Commodore from 1985 until the company's bankruptcy in 1994, with production by others afterward. The original model is one of a number of mid-1980s computers with 16-bit or 16/32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems.
While AAA was a reinvention and huge upgrade of the Amiga architecture, project Hombre was essentially a clean slate. It took what was learned from Amiga and went in new directions, which included an on-chip CPU with a custom 3D instruction set, 16-bit and 24-bit chunky pixel display, and up to four 16-bit playfields running simultaneously.
This accelerator board was designed for the Amiga 3000 and Amiga 4000. The accelerator board was famous for its high performance due to its 64 bit wide memory bus and PowerPC 604e processor. [25] According to Phase 5 it could sustain memory transfers up to 68 MB/s on the 68060 and up to 160 MB/s on the 604e. PowerPC 604e at 150, 180, 200 or 233 MHz
Minimig 120x120 mm PCB board (Nano-ITX size) [1] Minimig (a portmanteau of Mini Amiga) is an open source re-implementation of an Amiga 500 using a field-programmable gate array (FPGA). Minimig started around January 2005 as a proof of concept by Dutch electrical engineer Dennis van Weeren.
MS-DOS compatibility was a major issue during the early years of the Amiga's lifespan in order to promote the machine as a serious business machine. In order to run the MS-DOS operating system, Commodore released the Sidecar for the Amiga 1000, basically an 8088 board in a closed case that connected to the side of the Amiga.
The best-selling Amiga games sold about 25,000 copies in 1986, said Gordon, compared to 125,000 to 150,000 copies on the Commodore 64. [21] In 1994 BYTE wrote "The Amiga was so far ahead of its time that almost nobody – including Commodore's marketing department – could fully articulate what it was all about. Today, it's obvious the Amiga ...
