Checkmate A1500 Plus, A1200, CDTV Keyboard ?

Hi,
Looking for some help, I have backed the new cases being made by https://www.checkmate1500plus.com/

I plan to fit my A1200 into a black version of this case, I have a Lyra2 PS2 keyboard adapter left over from a previous tower conversion, so I can connect a PS2 keyboard and all will be good.

But..

In my collection, I have a CDTV and A2000 keyboard, while I have seen posts for connecting a 2000 keyboard to an A1200 via an upturned socket etc, what I think would look even better is to use my CDTV keyboard.

So, I am just asking if anyone has experience doing this, I've found pin outs for the CDTV keyboard on here and plan on having a go making an adapter but if someone has already done it, it would save time and may even save my A1200 from me doing something wrong.

Any thoughts?

No reason you wouldn't succeed. The protocol is the same.

The problem will be that the expansion card orientation and location is different in an A1200 board compared to the A500 and the external connectors are located in different places so the backplate will need to be redesigned.

The Checkmate A1500 plus design takes this into account.

sorry i'd missed the alternate backplate info, the initial kickstarter didn't mention it. I may need to get 2 A1500 Plus cases now.
