The ACA500 is a budget card. That means: It may not always do exactly what you expect it to, especially
when it comes to compatibility with different brands of CF cards. Every ACA500 has been fully tested with two
CF cards at the same time, so you can be sure that your CF card slots are physically and electrically OK.
However, you may find that some CF cards don't work at all (for example they keep the computer from
booting), or a combination of two CF cards doesn't work, although each single CF card of that combination
works if inserted on their own.
This is a compromise that we had to make in order to reach the extremely low cost of the ACA500. If you
encounter a CF card that doesn't work, you will most likely find another brand that will work. There is no single
brand that we can recommend, and no special size that we can recommend. We've found that expensive
brand-cards work fine for one size, and the same expensive brand doesn't work for another size, and we've
found the same for low-cost generic CF cards.
Please understand that we cannot answer support questions about CF card compatibility. However, we'll do
our best to show some cards that are reported working or not-working in our Wiki on http://wiki.icomp.de
Our resellers will most likely offer CF cards that are known-good with the ACA500.
Limited hot-swap functionality
Despite the limited amount of hardware on the ACA500, we've tried our best to add hot-swap compatibility to
the “Aux” CF card slot. If you have successfully booted your Workbench from the “Boot card”, you can insert or
remove a FAT-formatted CF card into/from the “Aux” slot while the computer is switched on. However, this
only works with a small selection of cards, and proper function even depends on your boot card.
If hot-plugging was not successful, the computer will show this by quickly blinking with the power LED and
stopping all other operations. In that case, please remove the card and try inserting it again. If this does not
work after four or five attempts, the card you're trying is most likely not hot-plug compatible with the ACA500.
Please do not open any support ticket for questions about this hot-plug feature. It is impossible for us to add
full hot-plug compatibility into this budget product. If one CF card doesn't support hot-plug on the ACA500,
then please try different brand or size until you find one.
Support
If you need assistance with your ACA500, please ask your reseller. In the rare case that the technicians of
your reseller don't find a solution, they will forward your case directly to individual Computers. Please
understand that we can only answer direct support questions if they have been forwarded by your reseller, or if
you're a direct customer.
There have been misunderstandings in the past, because employees of resellers and individual Computers
(technicians, developers, programmers) are active in Amiga-forums. However, these activities are pure hobby
activities – these people care for the Amiga just like you do. Please understand that none of the internet-
forums is a support forum for our products. The official product support goes through your reseller only.
Individual Computers hopes this product gives you years of enjoyment and utility for your beloved Amiga 500
or 500+. Please note that Individual Computers is making more products to make life with your A500 a little
better:
Micromys V4
This adapter allows you to connect an optical PS2-mouse with scrollwheel to the Amiga. Compared to the
original Amiga mouse, optical mice are much more precise and they often have much higher-quality buttons
than the bulky ball-mouse by Commodore. Just connect this adapter between the mouse and your Amiga.
Indivision ECS
This is a flicker fixer – a component to be put inside of your A500 that converts the video output into VGA, so
you can use a modern flat screen. Flat screens are much more friendly to the eye, and they consume less
power than the old tube monitors. However, only a very small (and mostly expensive) range of flat screens can
display the video modes that the A500 produces, and so it's most of the time more cost-effective to go with
Indivision ECS and any low-cost flat screen of your choice.
ACA1220
This accelerator is based on the first Motorola processor that was truly 32-bit in all aspects: The MC68020.
Originally developed for the A1200, it can also be connected to the ACA500 to give you 128MBytes of memory
and more CPU power for your workbench applications. The ACA1220 is available in different speeds from
16.67MHz to 25MHz (*).
