Amiga A500

ACA500 Plus Enclousure/Case Amiga
ACA500Plus Individual Computers Amiga A500 A500 Plus
ACA500plus for the Amiga A500 and A500 Plus is the successor to the popular ACA500. The ACA500plus is an external expansion which is plugged to the left expansion port of your A500 or A500+. There is no need to open the computer at any time. This includes a new revolutionary method that can turn your 512k trapdoor memory expansion into chipram! If your Amiga is equipped with an ECS Agnus chip and said internal 512k memory expansion, you can turn your computer into a 1MByte-Chipram computer, just by selecting a menu item in the configuration menu of the ACA500plus! A lot of stock A500 computers with board revision 6 or higher have this exact configuration. The ACA500Plus houses a MC68HC000 processor clocked at 14.1MHz as standard, This will give your computer more than a double-speed boost. If that's not enough, you can choose overclocking to 21, 28 or even 42MHz. Overclocking success is not guaranteed. By attaching an ACA12xx or Blizzard 12xx accelerator, you can make your A500 faster than a stock A3000. The ACA500plus comes with essential software pre-installed in it's large flash. This includes fully licensed Kickstart versions V1.2 and V1.3 for backwards-compatibility, and Kickstart V3.1. You can install a fresh copy of Workbench 3.1 using the built in installer which is included within the ACA500Plus. All you need is an empty CF card, and you can install OS3.1 with a few key presses. After that's done, you can use the second CF card slot to exchange data with a modern PC: The ACA500plus supports PC-formatted cards and long filenames out of the box, no special installation required. CF cards are handled like hard disks on the Amiga-side. You can use HDtoolbox or HDinsttools - whatever you prefer. Even the two popular 64-bit addressing modes are implemented: Both TD64 and NSD64 command sets are supported, so whatever your preferred filesystem requires, you can use it on your ACA500plus setup to access flash cards that are larger than 4GBytes. Speed-wise, the CF card slots are faster than most hard disk controllers that are available for other Amiga computers. The ACA500plus even outperforms the SCSI controller of an A3000! Many users will want to use the ACA500plus with the popular WHDload software, which lets you install games on CF cards instead of swapping floppy disks if you want to play a different game. WHDload lists the 68010 processor as a minimum requirement for using the Quit-key and return to the Amiga's Workbench. The ACA500plus has special circuitry that lets you use the WHDload quit-key at any time, although you "only" have a 68HC000 processor. This is supported by WHDload V17.2 and higher. Advanced floppy control: If your computer has a defective or even a missing floppy drive, the ACA500plus can handle this. With the built-in "boot selector" circuitry, you can turn an external drive into a fully-compatible df0: drive. In addition to that, the floppy control functions allow you to make external drives invisible, although they do not have an off-switch. This saves you the work of (un)plugging drives in order to make older floppy-based software compatible. The ACA500plus features three expansion ports:
  1. A1200-compatible clockport
  2. local 16-bit expansion port
  3. A1200 CPU card connector
The A1200-compatible clockport can be used for expansions that were initially designed for the clockport of the A1200, for example Catweasel MK2, Delfina or RapidRoad. Please note that some drivers may require patching in order to work on a non-A1200 computer. Contact the vendor of your A1200 expansion to find out if they provide such a driver. The fast 16-bit local expansion port is reserved for our network expansion X-Surf-500. The A1200 CPU card connector is meant for further CPU and RAM upgrades. It is guaranteed to work with our ACA1220, ACA1221(ec, lc), ACA1232, ACA1233(n) and ACA1234 models. Our older ACA1230 accelerators are not supported. We will therefore only answer support questions about ACA1220, ACA1221(ec, lc), ACA1232, ACA1233(n) and ACA1234 accelerators. The same applies to old Blizzard accelerators by Phase 5: IComp have done their best to make them work, but there are limits to what we can do. Please keep in mind that the A500 is a 16-bit architecture, and the Blizzard accelerators have been developed for the 32-bit architecture of the A1200. Another new feature of the ACA500plus is it's capability to make use of a real time clock (RTC) that an A1200 accelerator provides. This keeps the clock port of the ACA500plus free for other uses. Further, an RTC that is located on the trapdoor expansion of your A500 can be used. This kind of flexibility was not available on the predecessor ACA500. With all these expansions, certain software may be incompatible. However, this is not a reason to unplug the ACA500plus, as it features an advanced cloaking mode that lets you downgrade the computer to standard memory configurations with minimal expansions (like Action Replay) or even no expansions at all, your choice of Kickstart ROM, running at the original 7MHz speed. Even if your computer does not have an internal 512k trapdoor memory expansion, the ACA500plus can not only add this, but even emulate the cycle-exact speed of the internal expansion with the same slow-down effects that an internal memory expansion has. In other words: There is no reason to unplug the ACA500plus at any time.   Package includes:
  • ACA500plus with DisMo, 68HC000, 8MB RAM, 8MB Flash
  • Short instruction manual German/English
  Software included in the flash ROM:
  • Kickstart V1.2, V1.3, V3.1
  • Full OS3.1 disk set with fully automatic installer
  • Action Replay 3 (patched for ACA500plus)
  • HRTmon
  • Thor's 040/060 libraries as resident modules
  • Thor's mmu and memory libraries
  • Network software, TCP/IP Stack for X-Surf-500
  Enclosure/Case is NOT included but available as an option.   Note: ** We don't support or advise the use of the Meanwell PSU or its variants unless its an original Amiga PSU l that has been recapped (better), AT PSU or the CA-PSU. The primary reason is the PSU is the heart of the Amiga and reading the Individual Computers forum, the PSU is the 2nd item to question if there are issues. The number one issue is the socket on the Indivision is not pushed down enough as it does require a lot of pressure.

CA-PSU Commodore Amiga Individual Computers
CA-PSU Amiga A500, A500 Plus, A600, A1200
CA-PSU Amiga A500, A500 Plus, A600, A1200 (CA-PSU stands for Compact Amiga Power Supply Unit), where "compact" designates the three target computers A500, A600 and A1200. It is the first power supply on the market that fully complies with the original Commodore specifications, introducing cable drop compensation for best regulation that even settles the voltage drop in the input filter of the target computers. This means that the voltage on the main 5V rail will never deviate more then 0.9%, measured inside the computer - no matter if the computer is in vanilla configuration or heavily expanded. Conventional power supplies will either supply too-high voltage to a vanilla machine, or too-low voltage to an expanded machine, causing malfunction or even defects. This cannot happen with our cable drop compensation technology. Technical data in short:
  • 5V, 5A, ripple/noise 50mV max. (typically 30mV)
  • Overload on 5V tolerated up to 8A for 30 seconds
  • 5V load regulation <0.6% typical, max. 0.9% under overload condition
  • 12V up to 4A
  • -12V, 0.1A
  • Modern, high-efficiency DC-DC converter technology
  • Total output power up to 60W
  • Fanless, silent, extremely low heat
CA-PSU is a two-brick solution: One mains-connected power brick and the CA-PSU converter box with the switch and square 5-pin DIN connector to the computer. This moves the power switch a lot closer to the computer, reducing the probability of inadvertent switching, for example if the power supply is under the table near your feet. CA-PSU has the best overall efficiency on the market, with a worst-case efficiency of 80.1% (best case >82.5%). The best competing product peaks at just over 70%, and some original Commodore power supplies have an efficiency of only 55%. This means that with our CA-PSU, there's less total heat, less power consumption and a longer life expectancy because there is less stress on the components. Naturally, CA-PSU features over-voltage protection - every modern power supply does. We wouldn't consider it worth mentioning, but this protection is part of a more complex block to protect your valuable classic gear: There are two critical moments that need to be taken care of: Switching on and off. CA-PSU has a controlled 5V ramp-up when switching on, ensuring safe power-up of heavily-expanded machines. Traditional power supplies without such a controlled start-up ramp tend to "swing in" to the target voltage, which might cause malfunction or even defects. Further, switching off will start a short timer, ensuring that the next switch-on event can't happen until a few seconds after switching off. This ensures that capacitors in the computer and expansion gear are sufficiently discharged, and switching on won't cause 3.3V regulators of modern expansions to oscillate, which may cause severe damage. In the unlikely event that these elaborate precautions fail, CA-PSU is covered by a German product liability insurance. This new production run of CA-PSU includes an international power brick that directly plugs into the socket (no mains cable). International adapters included are:
  • Central Europe
  • United Kingdom
  • Australia
  • USA
CA-PSU is compatible with worldwide grid voltages and frequencies (110-240V AC and 50 or 60Hz).

Keyrah V3 allows you to connect original keyboards of classic computer systems like the Commodore 64 or the Amiga 1200 to modern computers (e.g. PC, Mac, or the Raspberry Pi) via USB. It also supports digital joysticks and analogue paddles of such classic systems, which will be converted to standard HID game controllers. Supported systems with this model are:
  • Commodore C64 (all models)
  • Commodore SX-64
  • Commodore VIC-20 (VC20)
  • Commodore C16
  • Commodore C128D
  • Amiga 1200
  • Amiga 600
  • Amiga 500
  • Amiga 4000/CDTV
  • Atari ST (8-pin connector only)
  • PC XT / PC AT (with PS/2 adapter)
The following systems can be made compatible by mounting additional connectors on the circuit board or using adapters:
  • Commodore C128
  • Commodore C116
  • Commodore plus/4
  • Commodore PET (8296)
  • Commodore CBM2 (B-Series)
  • Amiga 2000/3000 (with PS2 adapter)
Keyrah V3's switch allows you to switch between the standard and a keymap that's geared towards emulation. This switch looks and feels like the original power switch of the Commodore 64, adding a third switch position that allows you to send an ACPI signal to shut down/power up your computer. To avoid triggering the shutdown procedure by accident, this third position is not locked, so the switch will always flip back from it if not held in place. For further safety, the ACPI signal is only sent to the computer after being held in this position for five seconds. The box includes the Keyrah V3 circuit board and a printed manual. USB cable is not included. PCB colour will vary.

ACA1234 Amiga Accelerator
ACA1234 Amiga A1200 Accelerator 68030 128Mb Fast Ram
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
  1. 127 MByte RAM auto-configuration
  2. 1 MByte RAM reserved for fast Kickstart re-mapping (you can also kickstart from other roms including 3.2).
  3. 8 MByte flash for installation files and Kickstart ROMs
  4. Local CF card slot as high-speed mass storage
  5. IDE speeder technology for read and write
  6. Drivers for PCMCIA-CF card reader in flash
  7. ROM and OS 3.1 in flash, extremely fast system installation
  8. Clock rate can be reduced (reset required)
  9. Card enable/disable in software without power-cycling
  10. Faster clockport gives 55% speed increase
  11. 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.   Image showing the ACA1234 50Mhz version. 25Mhz CPU is copper top. 33Mhz is a black ceramic CPU
