Help please identifying this 6809 Eurocard board.

Hi Folks,

I have just bought this 6809 base Eurocard on a bit of a whim and I'm trying to identify it.

In addition to the 6809, it has a dual port UART ((SCN2681), 8KiB RAM, an NEC keyboard/display controller and a sneaky little PIC in the top/right socket.

Does anyone know what this is?


Thanks.

Andy.

I'll bet it's a MICROD CB-9201.

Cheers Bruce,

I'd seen the markings on the silkscreen (obvs ) but couldn't find any more.

Thanks.

Andy.
