Turbo card installation

Installation of the card should always be performed with the Amiga being powered down.

Wicher 500i rev.2c turbo card has been designed for installation inside the Amiga A500/A500+ computer.

After removing the original MC68000 CPU, one can start the proper Wicher 500i rev.2c turbo card installation. In order to

carry it out, the pins found at the bottom side of the turbo card, should be carefully inserted into the U1 chip socket and

then the card should be pressed gently until it seats firmly.

Then one should connect the two provided cables to the card's SV1 port, following the instructions presented below.

SV1 port location

INT2 signal of the SV1 port should be connected to the 21

pin of the U7 (ODD CIA A) chip, whereas OVR signal of the SV1

port should be connected to the 29

pin of the U5 (Gary) chip. Both of the aforementioned U5 and U7 chips should be

easy to locate on Amiga's motherboard.
