The RSL8 board is not fully IEEE 996.1 (PC/104) compliant. The following restrictions and
differences to the IEEE 996.1 specification apply:
–
connector is compatible but the monting holes are not
–
The interrupt lines are pulled up with 8k2 resistors to Vcc (EISA specification)
instead of 2k2 (IEEE 996)
–
only 8 bit I/O transfers are supported
–
16 bit I/O and memory and 8 bit memory transfers are not supported
–
DMA transfers are not supported
–
MASTER# transfers are not supported
The following restrictions apply to the additional bus signals:
–
I2C_ALRT# is not supported
–
+12V, -12V and -5V are not supported
Important Note
Do not connect bus drivers/receivers with integrated bushold circuit to the PC/104
signals. This may disturb proper operation of the RSL8 board or add-on boards.
