Amiga Hardware DatabaseCompany Computer System Associates, USA | Date 1986 | Amiga A1000 |
- processor card - Turbo Amiga CPU (CSA 00920)
- 68020 and 68881 @ 14.3 MHz, PGA, synchronous
- both chips are overclocked 12 MHz units
- when addressing the Amiga custom chips or the motherboard memory, the 68020 throttles back to 7 MHz
- 68000 fallback mode selectable by jumper
- optional static memory card - Turbo Amiga Memory (CSA 00919)
- without this RAM card, the 68020 performs 15% slower than the original 7 MHz 68000, because of the additional time it takes to generate 24 bit addresses for the motherboard memory
- the card fits into a free Zorro I slot, but instead of transmitting data via the Zorro bus, it attaches directly to the CPU card via four ribbon cables, and create a 32 bit memory bus
- with the memory card installed, performance is increased to 2.8 times of a standard A1000
- sixteen 32 pin DIP sockets for up to 512 kB static RAM
- takes 32k×8, 100 ns SRAM chips in groups of four
- does not autoconfig its memory
- multiple Turbo Amiga Memory cards can be installed
