ACA1234 Amiga A1200 Accelerator 68030 128Mb Fast Ram
£233.33 Ex. VAT
ACA1234 Amiga A1200 accelerator is the latest 68030 CPU based card from Individual Computers. This is far more than just another 68030 accelerator, it adds high-speed mass storage, improving the overall speed experience of your A1200 even more than the IDE speeder does, which is also available on this model. With 8MBytes of local flash memory and a local CF card slot, the ACA1234 is ideal for the hobbyist or power user.
While iComps IDE speeder technology accelerates the onboard internal IDE port to raw transfer rates of up to 14MBytes/s (resulting in every-day performance of around 5MBytes/s with CF cards, or up to 9MB/s with physical hard drives), the ACA1234 onboard CF card slot can exceed 9MBytes/s. Other than competing products, both options do not require opening the computer or even removing chips from their socket. The IDE speedup to PIO mode 4 is activated with a software setting. NOTE: The IDE speeder feature is not available if connected to an ACA500Plus.
The ACA1234 boards take memory performance to the limit of what a 68030 processor can transfer in a burst sequence: It’s a sequence of four 32-bit transfers in four CPU cycles, You therefore get the best performance per MHz compared to other 68030 accelerators both modern and and legacy 68030 designs. In addition to that, the ACA1234 makes sure that the exec base in burst-capable, cacheable 32-bit fastmem.
Another huge improvement over older accelerators is memory mapping to the legacy 0x00c0.0000 address. This is the location where many A500 games expect a trapdoor memory expansion. The ACA1234 cards give a good compatibility boost only because of this little chunk of memory in the right place.
The ACA1234 is PCMCIA-friendly: It will not disable the onboard PCMCIA slot, so you can continue to use a networking card or a CF card adapter in that slot. For the easiest-possible transfer of files, drivers for a PCMCIA-CF card reader are included in the flash of this accelerator card. You can access PC-formatted and Amiga-formatted cards with ease, straight out of the box. you can even boot from a CF card in the PCMCIA slot..
Customers who are returning to the “hobby Amiga” often have the problem of lost installation disks, or even a defective floppy drive after all these years. Installing a system becomes almost impossible in such cases. The ACA1234 includes media to install a system in such a case as well: Both ROM and install disks (Workbench 3.1) are licensed from Hyperion and included in the flash of the ACA1234. The installer, which has been successfully used with the ACA500Plus and Buddha Plus One IDE Controller as well, installs a system way faster than it will ever be possible with floppy drives – and it only take a few mouse clicks. This includes automatic partitioning of media that’s larger than 4GBytes!
All features
- 127 MByte RAM auto-configuration
- 1 MByte RAM reserved for fast Kickstart re-mapping (you can also kickstart from other roms including 3.2).
- 8 MByte flash for installation files and Kickstart ROMs
- Local CF card slot as high-speed mass storage
- IDE speeder technology for read and write
- Drivers for PCMCIA-CF card reader in flash
- ROM and OS 3.1 in flash, extremely fast system installation
- Clock rate can be reduced (reset required)
- Card enable/disable in software without power-cycling
- Faster clockport gives 55% speed increase
- Field-proven high A1200 compatibility
Memory of the ACA1234 is auto-configuring. This means that all memory is available from a power-up without installing any software on the computer.
If you do not require full speed, the card can be slowed down in order to save power or reduce heat. You can also increase the speed beyond rated clock rate for a trial period – if you find that your CPU can accept a certain level of overclocking, you can purchase a permanent overclocking license.
Some software does not like accelerated execution. For these cases, the ACA1234 can be switched off and put into a “stealth mode”: This will allow you to run such software without having to remove the accelerator. Returning to 68030 operation does not require the computer to be power-cycled.
The clockport of the ACA1234 can either take an RTC module, or a different clock port device. Operation of such a clock port device is 55% faster than with the internal clock port of the A1200 computer, provided the drivers support the address of this port. This function is available in all modes of operation on an A1200 computer, and on select ACA500plus models with updated CPLD.
Last not least, the ACA1234 features iComp’s field-proven A1200 motherboard interface. Some A1200 main boards have been delivered with the wrong timing components and require modification for reliable use with accelerators. With our interface, the ACA1234 is less likely to require these board patches. Although the ACA1234 will work reliably with any patch level of the A1200 main board, you may still want to perform these patches, as they also fix graphics glitches with Super-Hires resolutions of the AGA chipset.
Package contains:
- Accelerator with RAM and CPU assembled
- Short installation manual
You will need in addition to that:
- Motherboard patches as described by Commodore: A1200 capacitors E123C and E125C may need to be removed.
- A proper power supply that provides good regulation, even when loaded with expansions like the CA-PSU
- If desired, a PCMCIA-CF card reader
Processors on this card are used and have scratches.

How are these brand new?
In 2016 840 Amiga users made it possible in supporting a Kickstarter to reproduce the Amiga 12000 case, the new A1200 cases are made using Injection Molding manufacturing technique to produce top and bottom shells as well as trapdoors and parts. The process implies the use of 3 new moulds, the first one is for the top shell, second mould for the bottom shell and last one for trapdoors and parts, all produced using brand new moulds.Enhancements galore:
The Amiga community has never died and some have produced some great add-ons over the years to make sure the Amiga is still relevant and useful today as it was back in the 80's/early 90s and these cases take full advantage of that weather that's simply transferring your existing motherboard from your existing Amiga 1200 or have a luxury of installing a MiST FPGA Board. Below are few more enhancements: [accordion] [pane title="External CF Adaptor" start=open] A CF slot can be opened up on the side of the A1200 case to allow easy access to what would be the CF card within the A1200 itself. [/pane] [pane title="MiST FPGA Board"] MiST is a FPGA based modern board that implements classic 16bit computers like the Commodore Amiga, Atari ST and 8bit systems like the Commodore 64, ZX-Spectrum, MSX, Atari XL/VCS, Apple II, Colecovision, Sega Master System, NES, SNES as well as Arcade machines. The primary difference between the MiST is that its NOT emulation. The new A1200 case has mounts to mount the MiST FPGA within the A1200 case. [/pane] [pane title="Raspberry PI"] Yes you can mount a Raspberry PI 2/3 within the new A1200 case with the use of the mounts already part of the case for a nice clean solution.

What are ADF files?
ADF files is the standard Amiga Disk Format for floppy disk images. no different to Sega or Nintendo roms, ADF's are images of Amiga floppy disk games. Not only could you have access to a huge back catalogue of retro Amiga games, but there are still brand new games being released today, for example: Raid over Moscow or Bridge Strike these are all available as ADF files. But you not limited to games or programs, but you have access to tons of Amiga demos (if your into that scene).What are gotek drives in detail?
