My QIC-02 interface card. It is an 8 bit, ISA card. Pretty much square.

J1: ISA 8 bit connector

J2: 2*25 pins header for connecting an internal QIC-02 drive (not all pins
    are actually used.) Pin number 35 is missing, to allow for a polarized
    plug with hole number 35 filled.

J3: External 37 pin DB37F connector for connecting an external QIC-02 drive.

SW: configure I/O base address: (exact details unknown)
    My settings: 1..7: off, 8..10: on. This works out to 0x300 (factory
    default?) Probably the switches 1..9 correspond to address lines.
    Pin 10 maybe related to QIC-02 bus parity??
    
W1: Jumper. Related to DMA???
    My settings: jumper present.
    
IRQ: Select interrupt line. Choose one from 2..7, beware to avoid conflict
     with other devices. My setting: 5
     
DRQ: Select DMA ReQuest line. Select 1 or 3, depending on which DMA channel
     you want to use. Must be the same as DACK setting. My setting: 1.

DACK: Select DMA ACKnowledge line. Select 1 or 3, depending on which DMA
     channel you want to use. Must be the same as DRQ setting. My setting: 1.
