IF PRINTED CIRQUIT BOARD WIRING VIEW WAS ONE TONE LIGHTER, THEN 5 STAR RANK HAS TO BE MY CHOISE.

Very usefull, good quality drawings !
Muito útil encontrei todas as informações necessárias.
;
Wanting to repair a neighbours tape recorder I needed the necessary information, it makes it easier. Although the service manual is described as "Language : English" To my dismay I found that it is entirely written in German, a language I do not understand. At least I now have the schematics which will help of sorts. I may not use this service again due to the laguage difficulty after all when it states English you do not expect it to be entirely in another language.

Good quality (clearly readable) manual, I'm glad I could find it here, at a bargain price!
(7) CDCC parallel I/O <Data receiving> There are two modes in this unit. One is the CPU receiving mode and the other is the DMA receiving mode. In the CPU receiving mode the CPU receives the command data from the PC, and after the CPU is switched to the DMA mode, it receives the image data and writes to the DRAM directly. CPU Receiving Mode
STROBE
BUSY ACK 90 µsec 0.5 µsec
STROBE
BUSY ACK 1.5 µsec 0.5 µsec
BUSY goes HIGH at the falling edge of STROBE. The data (8 bits) from the PC is latched in the data buffer at the rising edge of STROBE. The pulse width of ACK differs according to the speed MODE as shown above. BUSY goes LOW at the rising edge of ACK. <IEEE1284 support> This supports the IEEE1284 data transfer with the following mode. Nibble mode Byte mode (8) Data extension This circuit extents the compressed image data which are received from the PC, and writes the bit map data to the FIFO. (9) Software support Supports 16 x 16 rotation, bit expansion, and bit search. (10)EEPROM I/O One output port and one I/O port are assigned.
