[N8VEM: 16161] ECB connector & signals

Gents,

I have a 64-pin DIN connector which has A+C rows, and looking at the SBC V2 schematic it doesn't seem like the SBC uses row B. At the same time, the 8-slot backplane has 96-pin DIN footprints, and routes all A+B+C rows.

Do you think that I can use a 64-pin DIN connector (rows A+C) for connecting my SBC V2 to the backplane? Also, do you know if there is any detailed description of the ECB bus signals? Thanks in advance.

Regards,
picmaster

SBC v2 uses only rows A & C. 
 
Row B is for expansion signals for processors other than the Z80;
e.g., 80C188 (SBC-188) and MC68008 (mini-M68k).

I seem to remember that Kontron is big on ECB so I would try their web site.

The N8VEM use of ECB is not exactly the same as the European usage, but seems to be consistent between N8VEM boards.

Best of luck,

Douglas Goodall

Wolfgang posted a whole set of Kontron schematics. 
 
The basic (rows A & C) ECB signals are little more that the Z80
pinouts brought to the backplane.  I think you will find the Z80
processor manual useful.

I must admit that my initial expectations for the ECB bus were similar to the bus used in MyCPU project - the project author defined his own bus for his homebrew project. That's why I asked for the bus docs.
Anyway, after Doug replied I checked in Google and found info for ECB. Thanks guys!

Hello PICMASTER,

the ECB-Bus was designed with 64 pins (row A + C) and for the Z80. I
have at home an SBC V2 with 64 pins, a backplane with 64pins and my
other PCB I developed with 64 pins. For special using (68000, Z8000,
Interrupz Controller) there are used the extension "row B".

On the Wiki You may find informations about ECB (KONTRON, ECB-Bus, ...)

Regards

Wolfgang

Thanks Wolfgang!
I have currently several 64-pin DIN connectors and will use them for the SBC and other boards, and will try to find 96-pin DIN female sockets for the backplane, "just-in-case" :).
