Hardware Installation (for PC/XT/AT)
Installation & Configuration of the Interface Card
The following paragraphs explain configuration and physical installation of the interface card.
Software installation and setup are covered in a separate section. After configuring your board, please
make note of the following: the I/O Base Address, the interrupt channel, the DMA channel, if any, and
whether or not the board is the System Controller. This information is needed for Driver488 software
installation.
The Personal488/AT has two DIP switches (S1 and S2), and three 14-pin headers (IRQ, DACK and
DRQ). The DIP switch settings, along with the arrangement of the jumpers on the headers, set the
hardware configuration.
Default Settings
Notice that S1 and IRQ set the interrupt response level, S2 controls the I/O base address, and DACK
and DRQ select the DMA channel.
