The IS200SRLYH2AAA MDX-UMC isa universal memory card for the STD Bus.
The MDX-UMC provides the user with the capability of
configuring the board to meet the system requirements of
ROM/EPROM and/or RAM. By the use of strapping
options, the user is able to IS200SRLYH2AAA configure pairs of sockets for
ROM/EPROM/RAM to form a combination memory board.
Other MDX-UMC features include 4K boundary addressing
and an optional wait-state IS200SRLYH2AAA generator to accommodate
slower memories for 4 MHz system clock operations. A
block diagram for the MDX-UMC is shown in Figure 2.

ROM memories. The memories are organized into an array
of eight devices with each device contributing one byte to an
addressable location.
IS200SRLYH2AAA MEMORY DECODE AND CONTROL
The memory decode and control section is responsible for
generating the necessary chip select and output enable
signals for the memory arrays. Timing within the memory
decode and control section is derived from the STD-Z80 Bus
control signals /MEMRQ, /RD, /WR, and /CLOCK.
The address buffer is responsible for isolating the STD-Z80
address bus from the memory array.
DATA BUFFER
The data buffer isolates the memory array from the data bus
and is controlled by the memory decode and control section.
MEMORY DEVICE SELECTION JUMPERS
Figure 3 shows how J1-J8 are configured to accommodate
the various RAMs, EPROMs, and ROMs.
Table 1 shows how the jumpers J1-J8 are related to
memory sockets. It is important to note that the memory
sockets are configured in pairs for a particular memory
device.
