I saw this RC2014 bus card for Sam Coupe on ebay.

Is it easily possible to do this on CPC also?

Gryzor:
What would you connect through it?

PS Quazar does really nice things for the SAM...

Bryce:
It's just a plane breakout board. We already have one. It's called an MX4 and you can buy them from @TotO (I already have one :) ).

Or the LambdaBoard with 3 slots : https://github.com/lambdamikel/LambdaBoard
Or the CPCConnector with 1 slot : https://github.com/lambdamikel/CPCConnector

Yes, is the short answer. None of the MX4 backplanes mentioned above let you plug RC2014 cards directly into a CPC which was surely the original question.

Building a backplane with the RC2014 bus pin out for the CPC would be easy but needs a little additional decoding logic. Looking at the kicad schematics for a couple of the IO modules it looks like they only decode the low address byte of IO addresses. So, for the CPC you'd need to pick a 'safe' high byte in the memory map and decode that too, to enable the IOREQ* signal to the bus.

And then port any drivers to the CPC of course. But that would be part of the fun of it, right ?
There are lots of modules, all available as kits, on the main RC2014 site and other third party ones too like this TMS9918 VDP.
Were you interested in any in particular for the CPC?
