Very good reproduction (copy) of original manual. Didn't have a parts list, but schematic was completely labeled with parts. Complete instructions on how to adjust mechanical functions of the 8-track deck. Well worth having and at a very reasonable cost.
 ;
It's a full manual. All the parts are in there. I haven't found the problem yett, but I am working on it; hope I can rebuild the part myself. To make it more secure and unbreakable this time. Because the part has failed several times before and costs a lot to let it be repaired.
Thanks so much for this rich illustrated and parted manual.

I downloaded the document. The manual was complete, well scanned and everything was legible. I could zoom in see what I needed to know. There's not much more that you can ask.

It was complete service manual with all needed service informations. Thanks.

El manual esta muy detallado, los numeros de partes y los esquemas de despiece son correctísimos y muy claros, tanto para los técnicos experimentados como para los novatos.

[3] Downloading Sequence
A
� Downloading the firmware to the AUDIO DSP
Downloading the firmware to the AUDIO DSP is performed in 4 sessions. 1. After reset of the AUDIO DSP is canceled, DSPCS# is set to �L.� Then transfer of the initialization program 1 starts. 2. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �L.� 3. DSPCS# is set to �L.� Then transfer of the initialization program 2 starts. 4. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �H.� 5. DSPCS# is set to �L� then transfer of the initial values starts. 6. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �L.� 7. DSPCS# is set to �L.� Then transfer of the program for the main unit starts. 8. After the transfer is completed, it is checked that DSPCS# is set to �H.� Then DSPDREQB# is set to �H.� Downloading is completed. DSPCS# (Pin 50)
B
SPICLK (Pin 53) SPIOUT (Pin 55) DSPDREQB# (Pin 27) Approx. 110 msec Note: The above-mentioned pin numbers are those of the IC202 (SOUTH CPU). Transfer of the initialization program 1 Transfer of the initialization program 2 Transfer of the initial values Transfer of the program for the main unit
C
� Downloading the firmware to the FPGA
1. The FPGRM is set to �H.� 2. It is checked that SD2_OUT is set to �H.� 3. Transfer of the FPGA firmware starts. 4. After the transfer is completed, it is checked that DONE is set to �H.� 5. After a wait of 1 ms or more, FPGARST# is set to �H� (released). Downloading is completed. FPRGM (Pin 38) SD2_OUT (Pin 36) SPICLK (Pin 53)
D
SPIOUT (Pin 55) FDONE (Pin 37) FPGARST# (Pin 46)
Transfer of the FPGA firmware 1 ms or more
Approx. 200 msec Note: The above-mentioned pin numbers are those of the IC202 (SOUTH CPU).
