Hi,
Thanks to Hans van Mierlo for providing me with this chess computer so that, after its repair, I could analyse and perform reverse engineering, although unfortunately we are not in a position to emulate it at the moment.
As it is an uncommon computer and I don't think there are any videos of it working (maybe there are and I just haven't been able to find them), I have recorded some:
