I would not say the sparc was failure.
Problem was that the spracklen did IMO not really made much progress anymore.

If you see Mach III that was a progress over the 8 bit machines,
But Mach IV was only faster hardware and there was IMO not much
"Genius" anymore in the new portation, of course sainted chef could have bought hiarcs for the sparc module, mark was ready and he even won in Munich 1993 on a sparc machine PC.
But winkler did not want to pay enough when he did the negotiations with mark uniacke. So we will never find out how strong hiarcs on sparc could have been in 1993. IMO it could have been a milestone that could have rescued saitek.

As I said in Hiarcs site, I think the Spracklen never went beyond Par Excellence, but just improved it a bit here and there AND got lot better hardware. From that improvements came Mach series and his last Sparc try.
If you play any mach you will not detect a really new program, but a good Par Excellence going a bit further.
As I have said many times, any chess programmer -and in fact any creator of anything - has ONE try which he creates very early and the rest of his life is improvement of it.
The curve ism like this:
a) First beginnings, an idea in his childhood but promising
b) full development
c) improvements along a long period
d) reduction, deterioration, bad copies, retirement.

That shows why making the machine faster is not really helping.
As it seems to me the Mach III 16 bit program was less knowledge than the
Excellence program, when it comes to pins, pawn structures etc.
The disaster began with the par excellence, while the excellence program was capable to play with decent pawn knowledge, the par ex suddenly played one double pawn and isolated pawn after the other,
IMO the spracklen threw knowledge out of the program that was first in, to make it compute deeper.

My favorite thing about the dedicated Chess machines is that they are static. They always play at the same level even decades later. I bought the Excellence in 1988 or 1989. I couldn't beat it at its default level back then or even some years later. In late 2012, I started some serious self study on tactics. I thought I had improved and decided to challenge the Excellence to a game. Of course, it graciously accepted the challenge at its default level.

An enjoyable game especially considering it was my first win against it in roughly 24 years.

Is the magic gone if you run Stockfish on your computer. And if so why do you think ? Maybe because everybody has a home computer ?
In the golden years I couldn't afford those big chess computers. Today I sometimes enjoy to play a game against latest Stockfish on the Revelation II device via bluetooth connection to a fast i7 computer. Of course I never can win but I like the combination of a modern chess engine in a retro style chess computer. Feels like Mephisto Superman...;-)
