They don't say that "the Double Eurocard is NOT the same as the VMEBus"
they say that "the TMB12 is not compatible with VMEbus backplanes".
If you look at the Spec of the B12 and the B14 you will notice that
on the B14 the upper Edge Connector is used as the VMEbus Interface.
On the B12 it is used for Transputer Link-Connections.
I'm pretty sure that neither the VMEbus, nor the transputer-links be
very happy when they are connected to each other... ;-)
The lower edge Connectors on both boards use the Inmos-Interface, so
you can Connect the B12 and the B14 via some Inmos Backplane
(Inmos ITEM for example) and the B14 with some VMEbus System via the
upper edge connector.
btw. do you have some docs for the Parsytec BBK-PC2,
the MSC MB1T9S-PC-1 or HEMA TA1C. I'm currently writing new
Linux-drivers for transputer-link-interfaces and I would
like to support more boards than just the B004...
bye
