But compared to other 16-bit processors of this era it was in fact very powerful but yet still easy to use. For those interested I have put together what I know about the DCJ11.

Alternate Decoder Logic using a GAL

Instead of using the six TTL logic devices you can use a GAL16V8. This will save you sockets, soldering time and the need to purchase many different TTL logic components.

Combine the DCJ11 SBC with Breadboards

For more fun, projects or any advanced feature you would develop your own PCB that goes into the card edge slot, the expansion slot. However for many small projects this would be overkill. Here is one solution to this dilemma.
