CPU Main Board IC25 8032
Major Tasks of the CPU;
.Keyboard Reading
Transfers the velocity curve data to IC36 (SRAM
HM61 16). The key scanner IC37 (63H149) refers to
this table for determining akey dynamics and writes
it into 1C36 together with the key number and the
key event (on or off). The CPU reads these data
through IC37.
.LED lighting, LCD driving, A/D conversion

Most of addressing for I/O's and memories and some
of the functions are done through I/O gate array
IC23.
Shown below are the address map to be set by
62H195 and the block diagram of 62H195. (Fig. 1

Sampling 1C Main Board IC10 RF5C36
The Roland custom IC RF5C36 plays akey role in
the sampling system. The process is illustrated mainly
with the aid of photos, diagrams and charts.
NOTE (See Fig. 2)
The system clock for the sampling system is based on
the Xtal connected across IC10 pins 70 and 71. Left
under an unstable condition, XI will sometimes cause
TP7 (RAS) to be kept high. This problem will be
found on ealier products. This can be solved by add-
ing 10PF (C32) across main board IC10 pin 71 and
the ground point.

3-2. Sampling External Audio Input
IC3b of the output board can accommodate input
signals between -50dBm and OdBm. The compres-
sor consisting of IC3a, 4, 5, Q7, etc. relieves the sub-
sequent digital circuits from overload.

3-3. Reproducing Sampled Sound (See Fig. 5)
The sound data that the IC10 reads from DRAMs is
in a12 bit format. The 1C10 processes this data
with an ENVELOPE data to give aspecific contour
to the sound. The resulting is represented by an
expanded 16 bit data and then applied to the DAC
IC9. The DAC is configured to deliver each voice on
every 8th low INH. The all DAC outputs are to be
fed to one S/H circuit. The photo below shows
where only one sound is being reproduced.

They should differ from each other in content. While
displaying "SRAM Error", the CPU writes the test data
into the SRAMs for the second SRAM checking.

The test program stops testing without removing the test
