S8 is power switch for the emulator.
ON -- Normal operation.
OFF-- Add a current meter between TP3 or between J5 and J6 to measure the current
of whole system.
3.
Others :
3.1
TP1 – The CPU clock. The R2 will decide the CPU operating frequency. A small value
will get a higher frequency.
3.2
The user program EPROM should be installed in U2.
3.3
The user program area is from 8000H-FFFFH.
3.4
The pull-up resistors should be added externally. The resistance of pull-up should be
greater than 200K ohm.
3.5
SOUND1 is used to drive speaker. If SOUND1 pin is used as an output, then please
cut the trace between U3-97 and the base of Q1. Then add a jumper wire from U3-97
to JP3-17.
4.
Rework instructions for KP-2027 PCB.
4.1
Remove C3.
4.2
Isolate the left end of R3 from Vcc and add a jumper wire from the left end of R3 to
XOSC2.
4.3
Add a jumper wire from J7 to U3-77.
4.4
Add a jumper wire from U3-96 to JP3-19.
4.5
Add a jumper wire from U3-97 to JP3-17.
