- 68030 @ 50 MHz, PGA
- 68882 @ 50 MHz, PGA
- notes
- add-on processor board for the Commodore A2630
- plugs into the CPU socket of the A2630
- on older (Rev. 6) A2630s the Rocket Launcher fits only in 90° position and thus towers the A2630 about 3.5 cm
- works together with the Access 32 and DKB 2632 memory expansions

- 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

- processor card - Turbo Amiga CPU (CSA 00992)
- 68020 @ 14.3 MHz, PGA, synchronous
- Turbo Amiga CPU (CSA 00992B): 68881 @ 14.3 MHz, PGA, synchronous
- Turbo Amiga CPU (CSA 00992D): 68881 up to 25 MHz, PGA, asynchronous
- the 14.3 Mhz chips are overclocked 12 MHz units
- when addressing the Amiga custom chips or the motherboard memory, the 68020 throttles back to 7 MHz
- rev 4.2 motherboards have to be modified (a trace has to be cut and a jumper installed) to get the CPU card work, rev 3.9 motherboards work without problems
- 68000 fallback mode selectable by jumper
- optional static memory card - Turbo Amiga Memory (CSA 00993)
- 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 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 A2000
- sixteen 32 pin DIP sockets for up to 2 MB static RAM
- takes 32k×8 or 128k×8, 100 ns SRAM chips in groups of four
- the sockets can also take four 28 pin 64k×8 ROM chips containing Kickstart 1.2.2
- does not autoconfig its memory
- multiple Turbo Amiga Memory cards can be installed
- optional 16 bit RAM card adapter - DragStrip
- allows using two 16 bit Zorro II RAM cards as a 32 bit RAM expansion
- consists of a converter card (16/32 Bit Converter) and a connector board for the RAM cards (StepLadder)
- the converter card has to be installed in the first Zorro II slot (closest to the CPU slot) and connects to the CPU card via the same four ribbon cables
- the connector board with the RAM cards are placed between the CPU and converter cards
- any Zorro II RAM cards work like the Commodore A2052 or A2058
- the converter card has four 28 pin DIP sockets for 64k×8 ROM chips containing Kickstart 1.2.2
- notes
- the first 32 bit accelerator system for the Amiga
- all of the cards have four diagnostic LEDs for the four ribbon cables
- does not work with the Commodore A2090 hard disk controller - CSA has its own hard disk system for the card
