This multifunction IEEE-488 interface card takes 10K bytes of the memory space
including 8K byte ROM and 2K byte RAM. The starting address of the working
RAM is offset 8K bytes from the ROM starting address.
2.2.3. Operating Mode Setting
SW3 is a slide switch to select the operating mode. When it is set to “A”, this card is
compatible with the easy-to-use PCL-748 IEEE-488 interface card except there is no
real time clock. When SW3 is set to “N”, this card becomes Nl PC-II compatible.
It depends on the users which mode is selected. If the software package is already
developed for PC-II, then mode “N” can be used to eliminate the software effort.
However, for new software developing, mode “A” is recommended to get all the
benefit of PCL-848A/B. The PCL-848A/B does not offer the software driver to use
mode “N” and this manual offers the information for mode “A” operation only.
