I just picked up a working Arachnid 6300 for $120. I had to drill a lock and spend some time cleaning crud out of the target, but it works pretty well. The monitor has some burn-in but looks good in normal room lighting.
Some of the segments had rough edges from years of hits. I found that using a fine file I could smooth down the outside of a chewed-up segment so it moved easily in the spider.
I have a few questions if anyone's into these old games...
I still have a couple of segments that, intermittently, do not register a hit. If I tap on it with my finger when retrieving darts, it will register so I don't think I have any electrical issues. I think it's just not hitting the switches hard enough.
Is some amount of missed hits typical in these games?
Any advice for how to tune up the target more?
How tight should the bolts in the back be? Do I want the target as snug to the cushion as it can get without triggering the switches, or do I want it a little loose?
Any recommendations on dart tips? I have a random selection of Tufflex and Arachnid tips on hand. Not sure if there is a better choice available. (Lippoint?)
And lastly... My select/enter buttons often do a double-press. I have never had this happen on a microswitch before; switches seem to stop working as opposed to working doubletime. Is it likely that the switches just need to be replaced, or might there a problem with the switch debounce circuitry?
Thanks!
