What trackball is this ?

[Level42]

Anybody knows what trackball this is ? And if so, is it any good ?



Thx

It is an Atari trackball, most likely from a cocktail Missile Command. (Though it could also be from a Centipede--I'm not sure if they had switched to the plastic housing yet by that time).

hmmm, are your sure, I thought the cocktail versions also used the drum encoder.

I have one (MC cocktail). I rebuilt the TBs. Definitely not drum.

And Level, to be 100% sure what game that TB came from, all we need is the part number stamped on the top. (Looks exactly like mine though)

Just a second vote for MC cocktail.  I've come across them several times when looking for the 4.5" giants for the stand-up.  Almost always referred to as  Missile Command ball in auctions, I think even the first Centipedes had a more modern/less square and machined looking chasis.

ok, so it;s the big atari balls that use the drums.

Thanks gusy, so is it any good ? It's fairly cheap...

How cheap?
Do the optics work?
Are the bearings and rollers original?

A TB that age usually needs new rollers. And perhaps new bearings. If the optics don't work, you'll need new optics. And that yellow ball, how about replacing with a new white one.

Congratulations. Your cheap trackball just cost you a fortune and all you're really left with as original is the metal frame.

What Ray said, but there is some hope if the bearings are salvagable and the rollers aren't too badly hour-glass shaped.  You can do some reviving of the bearings by soaking them in WD-40 for a good while and working any rust off of them.  If the rollers aren't too bad, cleaning all the wd-40 out of the newly de-rusted beearings and lubing them really well with 3-in-1 oil (or your favorite machine lube) will take a rough spinning ball a long way toward smooth operation.

Oh, and the ball isn't yellowed, it was never cueball white.  They are "cream" colored.

Take a look at the rollers, if they aren't too badly concaved then go for it.

I've got one of those too.

Get yourself some hex wrenches, and take the entire thing apart, clean it out,  get some silicone lubricant for the bearings, and run them with a power drill until you break out all the dirt/dust.

My 5" trackball is now the centerpiece of my CP.
