TECHNICAL REFERENCE AND TROUBLESHOOTING
B.2.1
The core of the emulation component of the pod is the MC68HC705 C8A device at circuit board
location U4.. This MCU provides the required input/output information that lets the host
computer perform emulation. The host computer performs all simulation functions except
maintaining port values. The C8A MCU runs a program from its internal EPROM to generate
appropriate port values and communicate with the host computer.
The ICS05KJW software on the host computer lets the host computer become a simulator.
When the ICS requires port data, the computer requests the data through the host’s serial
connection to the 705C8A device. The C8A responds by sending the data to the host via the
serial connection. It is this arrangement that lets the ICS simulator interface with the real world.
The M68ICS05KJ pod’s 7.37-MHz crystal provides a clock signal for the C8A device. The clock
runs the device at a 3.69-MHz bus rate. Note that the simulation speed is less than the bus rate,
since the host computer is the simulator.
B.2.2
In addition to controlling the input and output port signals, the C8A MCU (U4) also controls
programming of the KJ/J1A devices in programming sockets U6 and U7.
The MC34063 device (U3) on the M68ICS05KJ circuit board generates the programming voltage
(16.5 Vdc). Switch S2 controls this voltage at the programming sockets. The ICS05KJW host-
computer software prompts you to turn switches S1 and S2 on and off at the appropriate times.

The Emulator
Programming
The C8A MCU differs from the emulated KJ/J1A device in that it
does not have programmable pull-downs.
M68ICS05KJ pod has external pull-down resistors, which are
selectable with jumper headers W3 through W16. To disable the
pull-downs, remove the fabricated jumpers from the corresponding
headers.
To program a 705KJ/J1A device, the EPROM of the device must
first be erased.
To program a 705J1A device, set the jumpers on pod headers
W18 through W32 to positions 1-2.
To program a 705KJ device, set the jumpers on pod headers W18
through W32 to positions 2-3.
