I’ve been holding off getting a Stern game to a fair extent because I haven’t yet developed the confidence in their long term repairability.
I don’t have the impression Stern is doing much to assuage such concerns. I find no mention of node board availability or prices on their homepage. The online retailers in my area at least don’t seem to sell them.
The JJP concept of using a Linux PC with a dedicated driver board, multiple graphic cards and a flash drive seems to me to be the better strategy (even if a few of the parts are yesterdays technologies and not so easy to find).
I can imagine the time on the assembly line hooking up wires could be reduced significantly with a bus system which appears to be the spike strategy. For repairability, however, a plethora of wires seems the better way.
I’m particularly intrigued by GB Pro. This being Spike 1 and older makes me even more nervous.
