I'm worried for the keyboard ribbon cable.
As for example in the ZX Spectrum "Issue Two" board the heatsink has burnt all the ribbons. Then Sinclair has released the "Issue 3b" with a heatsink relocated.
On the ACA630 the surface of the heatsink cover all the ribbon cable. It is as hot and large than you could cook a egg on it.
I'm going to look for a way to protect the ribbon cable.
BTW, some people asked me what I think about the ACA630, I did a video:
