Minimalist Europe Card Bus (MECB) - Motorola IO Card + Sound

This video follows on from my earlier Minimalist Europe Card Bus videos.

With my first Minimalist Europe Card Bus CPU Card finally completed, to my satisfaction. Next up, is my Motorola based I/O Card, which will finally enable a complete modular 6809 based system.

The Motorola based I/O Card includes a MC6850 Asynchronous Communications Interface Adapter (ACIA), a MC6821 Peripheral Interface Adapter (PIA), a MC6840 Programable Timer Module (PTM). And, in addition, I’ve added an optional Sound Interface via a SN76489 Digital Complex Sound Generator.

Join me, as I walk through the Schematic and PCB layout and then assemble and test my first card.
