|

|

Signal Definitions:
|
||||
|
||||
0 volts - This is connected to the main system 0 volts line. The reason for putting
|
||||
0V lines between the active signal lines is to reduce the interference
|
||||
between different signals.
|
||||
R/W (pin 2) - This is the read-not-write signal from the 6502 CPU, buffered by two
|
||||
74LS04 inverters.
|
||||
1MHzE (pin 4) - This is the 1MHz system timing clock. It is a 50% duty-cycle square wave.
|
||||
The 6502 CPU is operating at 2MHz, so the main processor clock is stretched
|
||||
whenever 1MHz bus peripherals are being accessed. The trailing edges of the
|
||||
1MHz and 2MHz processor clock are then coincidental. The processor clock
|
||||
is only ever truly 2MHz when accessing main memory.
|
||||
NNMI (pin 6) - Not Non-Maskable Interrupt. This is connected directly to the 6502 NMI input.
|
||||
It is pulled up to +5 volts with a 3K3 resistor. Both Disc and Econet systems
|
||||
rely heavily upon NMIs for their operation so take care. Note that NMIs are
|
||||
triggered on negative going edges of NMI signals.
|
||||
NIRQ (pin 8) - Not Interrupt Request. This is connected directly to the 6502 IRQ input. Any
|
||||
devices connected to this input should have open collector outputs. The line
|
||||
is pulled up to +5 volts with a 3K3 resistor. Interrupts from the 1MHz bus
|
||||
must not occur until the software on the main system is able to cope with
|
||||
them. All interrupts must therefore be disabled after a reset. Note that the
|
||||
main system software may operate very slowly if considerable use is made of
|
||||
interrupts. Certain functions such as the real time clock which is
|
||||
incremented every 10 mS will be affected if interrupts are masked for more
|
||||
than this period.
|
||||
NPGFC (pin 10) - Not page &FC. This signal is derived from the 6502 address bus. It goes low
|
||||
whenever page &FC is written to or read from. FRED is the name given to this
|
||||
page in memory.
|
||||
NPGGFD (pin 12) - Not page &FD. This signal is derived from the 6502 address bus. It goes low
|
||||
whenever page &FD is accessed. JIM is the name given to this page in memory.
|
||||
NRST (pin 14) - Not RESET. This is an active low output from the system reset line. It may
|
||||
be used to initialise peripherals whenever a power up or a BREAK causes a
|
||||
reset.
|
||||
Analog In (pin 16) - This is an input to the audio amplifier on the main computer. The amplified
|
||||
signal is produced over the speaker on the keyboard. Its input impedance is
|
||||
9K Ohms and a 3 volt RMS signal will produce maximum volume on the speaker.
|
||||
Note however that signals as large as this will cause distortion if the sound
|
||||
or speech is used at the same time.
|
||||
D0-D7 (pins 18-24) - This is a bi-directional 8 bit data bus which is connected via a 74LS245
|
||||
buffer (IC72) to the CPU. The direction of data transfer is determined by
|
||||
the R/W line signal. The buffer is enabled whenever FRED or JIM are accessed.
|
||||
A0-A7 (pins 27-34) - These are connected directly to the lower 8 CPU address lines via a 74LS244
|
||||
buffer (IC71) which is always enabled.
