JUMPER # DESCRIPTION
W33-W36
STD Bus Dual Port RAM Addressing
(24-bit) - defines the address range of the
dual port memory as seen by the STD bus
CPU. These jumpers, along with W28-W32,
map the ZT 8832 dual port RAM into any
contiguous 32 Kbyte block in the 16 Mbyte
address range for an STD bus supporting 24
address lines. Install cuttable trace CT14 (see
page A-20) to select addressing in the upper
8 Mbytes. Cut CT14 to select the lower
8 Mbytes. CT1 through CT4 must be cut (see
page A-17) before W33-W36 can be used.
