I needed the manual immediately and I got it immediately. I couldn't find this manual anywhere else on the net. The site was easy to traverse, and the price was very reasonable. I'll definitely be back for any future needs.

I received a good service manual, with good resolution. Improve the instructions for the purchase because they are not well understood.
For the rest, so good.
Thanks Angel.

Very good documentation for the Grundig 2077 model (as well as similar 800/900/1000 series radios). The first two pages are a summary of reception specifications and output capability. The third page is the tuner dial indicator and dial cord routing diagram. the final ~5 pages are the schematics for the various models (including 2077). The scan quality of the schematics are good, adn can be easily read if zoomed in. The documents are in German, not English as stated. It would have been nice to have the tuning sequence and settings, and some trouble shooting materials... or component and wiring map.

[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).
