Icomp ACA1221ec Kurzanleitung

ACA1221ec short manual
Dear Customer,
Thank you for purchasing a product from Individual Computers. We're sure that your new
accelerator will satisfy all your needs. However, we would like to emphasize that installing
the product in a desktop Amiga 1200 is not easy and requires some skills. Please make
sure that you have enough light at your desk and take appropriate anti-static precautions.
Installation should only be performed by experienced persons. In some rare cases, it may
be required to open the computer for installation. If you have never done this before, you
should seek aid of a technician.
Memory
The fast memory of the ACA1221ec is automatically added using autoconfig. Your
accelerator comes with 9MByte fast memory. If you set the jumper to "MapROM", a copy
of your Kickstart ROM is created in a reserved space of fast memory, increasing execution
speed of your system. This does not require any additional software.
There is even more physical memory on your card, but that cannot be addressed by the
68ec020 processor of your card. That memory can be made available with the forthcoming
Ram-disk tool for the ACA1221ec, which we will make available in our technical Wiki at
http://wiki.icomp.de.
Clock ports
The ACA1221ec has a pin header for the RTC-module, which is available separately. RTC
stands for "real time clock". If you either don't need an RTC, or already have one in your
computer, you can also use the header for connecting a Silversurfer, Delfina, Subway,
Catweasel MK2 or any other clock port device. Caution: This can only be done if there is
no other clock port device inside of the A1200!
The second clock port is a female port specifically made to accommodate a RapidRoad
USB host controller. Power for the controller can be taken from the white power connector
of the ACA1221ec. This port can also be used if other clock port devices are installed in
your system.
Installation
Please remove all cables connected to your computer and the PCMCIA card, if present.
Carefully place the A1200 upside-down on its keyboard with the floppy drive pointing to the
left. You can now see the lid that covers the computer's expansion slot. It can easily be
levered open with a flat-blade screwdriver.
Start by loosely placing the card near the CPU slot of the A1200. Now lift the back of the
accelerator a little and align the white connector with the CPU slot. Only when the card is
properly aligned, you may push the card into place with a little force. You may only push on
the back of the card. Never apply any force to the connector itself! The open wires of
the connector are very delicate and should not be touched at all.
Your computer is now ready for the first test. Bear in mind that the A1200 is an old
computer: It is very likely that the connector has acquired dirt over the years that is always
present in the environment, for example particulate matter and (if you're a smoker)
nicotine. Should the card not work right away, you should move the card a few times in its
