Well, I decided to install a rollerball in a Tempest to Major Havoc Conversion. I like the spinner for Tempest, just wanted to see how a RAM Controls rollerball would feel in this intead.

Spinner CP -

Snapped a few pics of the underside (to remember where everything is). Boy, I hate getting older...

Decided to cut the hole and mount 10/32 bolts to attach (so you cannot see it from the top. Hole was 2.490 x 2.490" to give me a tight fit. I chose 10/32s to give me a little wiggle room to install the rollerball.

Here is what it turned out -

I left the CPO on for now (have a NOS one to install....maybe, see below)

Now, I am going to redo the artwork from thisoldgame.com (thanks Rich!) and powdercoat the metal parts.

The Money shot for now (will get a separate thread once the art goes on)-

Since the rollerball has a 194 bulb, I elected to use only a piggyback from the coindoor lights. Gives a good glow, not overpowering... :D
 
Looks great, Joe! I did mine last weekend. I used bolts through the top. Looks good, but yours looks better. :)

So you can piggy-back the light from the coin door wiring, eh? Good to know. I'll have to do that this weekend. Mine's currently "glow-less."

How'd the rest of the conversion go? Rotating the monitor was a bit of a bitch for me, but it came out awesome and is working great.

I love this game.

Nice job! Rolligig is the way to go. Let us know how much better you like gameplay vs. the spinner.

Have you done the research in the differences in the rolligig and spinner PCB,s? IIRC, If the rolligig reacts too slowly there is a mod that needs to be done to a conversion PCB.

Love it! It is meant to play this way. Cannot wait to see what kind of scores I can put up....once I finish a few other games. :rolleyes:

The roller works great, plugged right in, no mods needed.
And no, I wasn't aware of a mod that may be needed to a conversion pcb...any info?

When I put together my MH conversion, I searched KLOV for every thread realating to the swap. What I remember reading was that someone had what they felt was a slow reacting rolligig and there was a resistor that needed to be changed out to fix it.

If it plays awesome, I wouldnt worry. I love my MH and I couldnt imagine playing with a spinner.

here it is from http://www.ionpool.net/arcade/mh/major_havoc_conversion.txt
+----------------------. :
Spinner & Whirley-Gig \ :
+------------------------`--------------------------------------------------.
:
Resistor R186, a 1k ohm 1/4 watt, is missing on some Rev B Kit :
boards. It is located near the LETA chip (137304-1001) at location 12N, :
underneath the Quad Pokey Adapter board on the main logic board. The :
symptom if the resistor is not loaded is very slow movement of Major :
Havoc by the Whirley-Gig. The added resistor doubles the response. :
Dedicated Major Havoc boards do not have a spot for R186. The dedicated :
Major Havoc board does not have a place for R186. It could be added by :
cutting a trace and adding the resistor, but I will not get into that here. : :
The Tempest and Major Havoc spinners have only one minor difference (which :
isn't hard to spot when you get the schematics out) -- The Optical board :
on the Major Havoc spinner has a 150 Ohm resistor, and the Tempest spinner :
has a 100 Ohm resistor. :
:
With the addition of R186, your Tempest spinner should now work properly on :
your Mojor Havoc board. :
:

+---------. :
Crystals \ :
+-----------`---------------------------------------------------------------.
:
Major havoc boardsets that were meant to run in a Tempest Conversion (ie :
using a Wells-Gardner 6101 monitor instead of an Amplifone) had slower :
crystals in them so that the monitor could handle the drawing rate. :
:
Original boards had a 12.0 and 10MHz while the conversion boards replaced :
them with a 10.0 and 8.9MHz respectively. :
:
Dedicated Conversion :
--------- ---------- :
Y1=12MHz Y1=10MHz :
Y2=10MHz Y2= 8.9MHz :
10 pin edge connector 12 pin edge connector :
:
Also the integration capacitors are DIFFERENT depending on the Y1 clock. :
If you change Y1 to a higher frequency, You will need to change the :
integration capacitor to a larger value (???). :
:
You can tell a 'conversion' board just by playing it because the sounds :
are about 3 steps down in tone, they also play much slower, which is :
probably good since you just can't do as much with the tempest spinner :
compared to a nice roller!

I was wondering why all of a sudden I was getting a ton of emails about the Major Havoc roller. I sell maybe four a month with just as many emails asking about them, but I've hit maybe 50 emails since this thread got going. Sheesh, like I don't already have too much to do. :)

BTW, like that panel with the hidden studs. Nice! Were those welded in or are the press-fit PEMs? I've never had good luck press-fitting PEMs into smaller gauge sheet metal. I think the cut-off for a good repeatable fastener insertion has been around 12GA for me, but I can work miracles when I have to.

Nothing but the best for you Dave! :D Is there anything else I can do to boost a little more business?

Very glad to hear that this post 10x the interest. I have to say the controller is 100% great! The play is spectacular compared to a spinner,

Thanks for the props on the hidden studs. It is going to be the best in the long run. I did not want the bolt tops to be seen (or felt) while using the roller.

I ended up welding them in. You're right, pressing is a pain on 14GA.

Now to figure out if Darrin will make a MH CPO that is not die cut so I do not have the spinner bolt pattern (where is used to be) exposed. That would be perfect!

You may want to wait on that. Last I heard, Rich (Rikitiki, TOG etc..) was thinking about making repro CPO's for MH conversions..
 
Thanks for the props - always appreciated!!

I've always liked improvements which make something look better. And, personally, I've never liked seeing bolt heads around the perimeter of controllers. This is especially true of trackballs and the MH roller. It's nice to see someone DO something about it. Now you just need the specialized artwork to match it. :)

I can attest to the quality of Rich's work. If anyone could make the special artwork for this conversion, it's him. In fact, if I were going to sell it myself, I'd go to him to make it for me.

I've been toying with the idea of press fitting PEMs into typical control panels, but I can't see a need for it, really. Though, if I'm making a brand new (read: custom) panel of some sort, I could try my hand at it again. If I practice enough, I can make it work with 14GA and even 16GA, but it's not easy.

Just to clarify, Darrin will be doing the run on Major Havoc CPOs, not Rich. I will let Rich or Darrin explain.
 
Awesome! Playing Major Havoc with the original roller is the way to go.

Word. There's no comparison between the spinner and the roller. If anyone else is thinking of doing this, Dave's controller is an absolute must. It's smooth, fast, super responsive, and looks great. I can't say enough good things about it. I'm so glad I sprung the extra $$$ for one. It was definitely money well spent.
 
Here are a few pics of mine...

My original marquee was very faded. I picked up an NOS overlay from Nash (thanks!), stripped the old one off (pain in the ass), repainted the wood and grill, and put the new one on:

Here's the game post-conversion, less the side art (next weekend's project???). The lines on the monitor are just the reflection of the doors to my game room:
