2-7. KEYBOARD/DISPLAY
INSTALLATION
When using the optional keyboard/dis-
play console, the following installa-
tion method should be used.
Orient the Evaluation Board and the
keyboard/display board so that their
component sides are facing up and the
P4 connector of the Eva1uat i on Board
faces the only edge connector of the
keyboard/display board.
Place the flat
cable between the two connectors so
that the even pi ns of the Eva1uat i on
Board connect to the even pi ns of the
keyboard/display board,
as shown in
figure 2-3a.
Fo"ld the cable between
the boards so that the board spacers
lock into the ho 1es on the boards, as
shown in figure 2-3b.
Both boards will
then have their component sirles facing
down.
2-8. PROTOTYPING AND
MEMORY-EXPANSION BOARDS
Prototyping and memury-expansion boards
can be connected to the CPU bus via P2.
AMC offers the fo11nwing optional pro-
ducts to accomodate these functions:
• Universal
Prototyping
Board
for
Mu1tibus (Am96/9410)
• 64-ki10byte dynamic RAM board for
standard
Mu1t"ibus
and
Evaluation
Board (Am96/1064).
• Two- and three-board backp1 ane for
P2
edge
connector
(Am96/4016-2S
and Am96/4016-3S)
• Six-board Mu1tibus-compatib1e card
cage with cooling fan (Am95/6440).
A card cage wi th . power supp1 i es is
also available (Am95/6448)
Prototyping boards can contain any type
of circuitry, including circuits that
capture the system buses.
The ArnZ8002
bus is described further in the section
entitled Principles of Operations.
2-14
Expansi on memory can be of any type
compatible with the available pins and
the buffered electrical characteristics
at P2 (see appendix A).
Dynamic-memory
refresh may be done on the external
board or it may use the CPU refresh cy-
cle, as does the on-board RAM.
The 64K RAM board supp1 i ed by AMC is
compatible with both the Evaluation
Board (through P2) and with standard
Mu1tibus
slave applications
(through
PI).
In either configuration, only one
of the two Mu1tibus edge connectors is
enabled.
Due to this dual use, dynamic
refresh is handled on the memory board
itself
rather
than
relying
on
the
AmZ8002.
The P2 connector of the mem-
ory board
supports 16 address
bits
whereas its PI connector supports 20
bits.
2-9. AmSYS 8/8 INTERCONNECTION
When an AmSYS 8/8 Development System is
used, P3 of the Evaluation Board is
connected to P4 of the Development Sys-
tem's CPU board as illustrated in fig-
ure 2-2.
A cable (Am96/4016-PCBL) for
connect i ng P3 to P4 is ava i 1ab1e from
AMC.
Alternatively, a cable can be
fabricated by using two Scotchf1ex card
edge connectors (3M part #3415-0001)
and one foot of Scotchf1 ex f1 at cab1 e
(3M part #3306/50).
A diskette-based program named HOST is
supplied with the Development System
for communication between the Develop-
ment System and the Eva1uat i on Board.
Execution of this utility on the Devel-
opment System allows Eva1 uation Board
operations to be controled through the
Development-system console.
However,
if the Am96/4016-KBD keyboard/di sp1 ay
console is attached, it takes priority
over all other consoles as the monitor
console.
