DIP switches

Two sets of DIP switches are located in the front right—hand corner of the Sidecar and are accessible after removal of the lid.
You may adjust the position of the switches with a screw driver. The DIP switches conform to IBM standards.
The switch position OFF is interpreted by the CPU as logical 1 - 5 volt level. The switches affect the following system components:

SWITCH FUNCTION
1 OFF: Boot
ON : System Diagnosis
2 OFF: 8087 Co-processor installed
ON : 8087 Co-processor not installed
3,4 Main memory capacity

7,8 Number of floppy disk drives
{see below)
SWITCH SETTING OF RAM CAPACITY
SWITCH 3 SWITCH 4 RAM CAPACITY
ON OFF 128k
OFF ON 256k
ON OFF 512k
OFF OFF 640k

If there is no RAM expansion, ie there is only 256K on the main board and no RAM expansion cards are installed, only one of the first two positions above may be used.
If you set DIP switches 3 and 4 to incorrect positions, the RAM check routine in the BIOS will only automatically recognize the first 246K of the installed memory.

Description of the row of 4 DIP switches (SW-2):

Switch ON = GND Switch off = VCC

The function of these 4 switches is to set the memory configuration of the 128k of Dual-Port RAM (DPR).
8k is used by the monochrome display and 32k by the color display.

Another 16k is used for maintenance of records and 64k is required fer data exchange. The remaining memory capacity of 8k is used for I/O registers.

SWITCH 1 (MON in Schematic) FUNCTION
OFF The address sector B0000-B1FFF is occupied in the PC address sector. With the switch in this position there must be no external vldeo card in the slot.
ON The address sector B0000-B1FFF is now located on the card. Reproduction via the Amiga is not possible. The address sector on the interface is switched off.
SWITCH 2 (COL in Schematic) FUNCTION
OFF The address sector B8000-BFFFF is occupied in the address sector of the PC. With the switch in this position there must be no external video card in a slot.
ON The address sector B8000-BFFFF is now located on the card. Reproduction via the Amiga is not possible. The address sector on the interface is switched off.
Location of the address sector in the Sidecar (PC) for data exchange purposes. (See below)
SWITCH 3 (SEL 2 in Schematic) SWITCH 4 (SEL 1 in Schematic) LOCATION OF ADDRESS SECTOR
X ON A0000 - AFFFF
ON OFF D0000 - DFFFF
OFF OFF E00000 - EFFFF
