Title: Joust to Robotron conversion
Post by: Wurstkopp on February 19, 2015, 09:29:55 AM
Got this cabinet for (almost) free and my first thought was: Fuck, what do I do with it? No monitor, no marquee, no joysticks, no buttons and the cabinet is almost half eaten up by wood worms. And last but not least: I hate Joust. ::) ;D

I have to confess that my first thought was to convert it to a Final Fight :lol:, I have a complete artset and always wanted a FF cab. But after a little brainstorming with arcade buddies and some searching I realized that the cabinet used to be a Robotron once (or at least it has the Robotron/Bubbles cabinet shape). After 10 years of searching I finally got my hands on a Smash TV cabinet so why not go for some more Eugene Jarvis awesomeness? :)

Thanks. :)

Next step: The missing monitor. Got my handy on a very cheap but untested Hantarex MTC 900, powered it up and... nothing. Of course. But how do the Robotrons say? The human race is inefficient and therefore must be destroyed. So a little closer inspection revealed the problem: All 3 fuse holders were corroded, one touch with a screwdriver and the metal crumbled away. I soldered the fuses directly to the chassis and...:

(Btw: Is it possible to attach pics and alter the size?)

Thanks. :)

This will get updated very soon. The biggest problem with everything related to arcade refurbing has always been that I'm living 150 Km away from my gameroom. I pretty much got used to it and took along smaller pieces like control panels etc. to my flat to work there on it, but when it comes to whole cabinets I'd have to drive over to my gameroom and do the work over there. But eventually I got sick of it and finally cleaned my cellar. Now there's a little bit of free space down there..! ;)

Cool project indeed! In two weeks my Robotron arrives (from container 7).
Will be interesting to see how you restore this. Mine needs some TLC too, but should be complete and working.

How the crap did you get that CPO off in one piece ???? Or did the worms help you ?

That was the easiest part. :)



count yourself lucky to have this little device. i will buy one tomorrow. my joust cpo kept me busy for 5 bloody days. it was incredibly sticky after the cpo was removed. i did try everything to get the glue off... but finally only patience did the job. will put the new cpo on the control panel tomorrow so the machine will be ready for the weekend.
Title: Re: Joust to Robotron conversion
Post by: Wurstkopp on February 19, 2015, 09:11:32 PM
Wait! I just remembered: I wanted to get rid of the worms and baked the whole panel for about an hour in the oven! No kidding. :lol:
After that I could just pull off the cpo.
Temperature was 75 degrees. Here's a pic of the transformer block in the oven (I will kill all the worms for sure!):

Please tell me you didn't find any worm corpses at the bottom of the oven...... ::) :shock: ::)

But.......I do dry electronics after I washed it .....like 6100 PCBs ;)
Title: Re: Joust to Robotron conversion
Post by: Wurstkopp on February 23, 2015, 11:40:18 AM
Thank god no, it seems they're all dead. But to be sure I'll paint the wohle cabinet with poisonous wood hardener today.

Meanwhile I had time to build in the Hantarex monitor and power up the pcb for the first time. Seems like a nice fuckup of the 4116s. :lol:
But I'm glad there's at least some life. PSU is working and supplies all the voltages, sound board seems to work too. I ordered 24 new 4164 RAMs, building the power adaptor meanwhile.






Title: Re: Joust to Robotron conversion
Post by: level42 on February 23, 2015, 12:24:58 PM
Yes 4116 to 4164 is always a good idea :)
Title: Re: Joust to Robotron conversion
Post by: anunaki on February 23, 2015, 12:39:07 PM
are these interchangeble? The datasheet looks isn't 100% the same

edit: googled it, pretty easy mod it seems
Title: Re: Joust to Robotron conversion
Post by: ajhippel on February 23, 2015, 12:47:05 PM
are these interchangeble? The datasheet looks isn't 100% the same

you have to mod the supply(connector) -  the 4164 does not need the -5v and +12v...

http://www.robotron-2084.co.uk/techwilliams4164.html

i just ordered a very very big stock of 4164 rams (1000 pce).. so if anybody needs some ;)
Title: Re: Joust to Robotron conversion
Post by: level42 on February 23, 2015, 12:52:32 PM
No and yes.

The big advantage is that the 16's need three voltages and the 64 only one (+5V).

You need to do some slight modding to use 4164s in places where 4116s used to be. Sometimes it's pretty easy f.i. with Williams boards using a special adapter (or just modding it yourself).

Title: Re: Joust to Robotron conversion
Post by: level42 on February 23, 2015, 12:55:53 PM
Actually.....the biggest advantage is that 4164s last a lot longer than 4116s.....the voltages are just another advantage ;)

I've used a single 4164 as a replacement on an Atari 800 RAM card succesfully too, just need to reroute some pins.

This is what you need to do if replacing a single chip:

Post by: Wurstkopp on March 02, 2015, 03:45:46 PM
Meanwhile I had painted the whole cabinet with primer two times, painted all the black parts and put the loose parts like panel, marquee, bezel, doors, locks etc. back in the cab. Now I'm waiting for the Hyundai mild silver metallic paint for the sides.

This is the progress so far:

Wooow looks great man! And you even go as far to get metallic silver paint for the sides.
Looking forward to seeing the result of that too.

I really hope the metallic silver stuff will work, it's a two component paint, basic silver + translucent paint:

Geez, can't wait to move on, tomorrow the metallic paint should arrive. I won't bore you with any more pics of the 4th, 5th and 6th priming + sanding of the sides, they all look the same but there are always one or two tiny spots that could and therefore have to be filled, then sanded and primed afterwards. Also I had to deal with some small chemical reactions where the filler underground tended to react with the primer (always use water based filler + water based primer or resin (english word for "Kunstharz"?) based filler + resin based primer, never mix between them!), but with the assistence of a friend who is a painter I now have it under control (--> isolation spray). I have never put so much work into one single cabinet but I won't stop now. Tomorrow is metallic mild silver paintin' time, I'll pray to Crom this night I don't fuck it up. :roll: :)

Post by: Wurstkopp on March 04, 2015, 09:59:42 PM
Ok, arcade is a really awesome hobby sometimes, but sometimes it's just not. First silver paint job (Level42 warned me :roll:), turned out pretty bad. At the beginning everything went fine (pic 3 + 4) but the second layer of translucent paint (that one obviously can hardly see while spraying) fucked the first silver layer up, because it's not possible to bring it on evenly. I don't believe it's possible to handle this stuff right, the only option I see is rolling.

Also there was not enough paint, which I realized too late when the light changed. Hope I have more luck on the second try. I defenitely won't use the translucent paint again. :(

For the record: You'll need at least 3 (better 4) cans of 400ml paint for the 2 sides.

EDIT: You'll need at least 4, better 5 cans!

Title: Re: Joust to Robotron conversion
Post by: level42 on March 04, 2015, 11:02:34 PM
Damn too bad....the first layers actually looked very tight !!

Expensive fuck up ?

It happens to all of us....the black on the Q*bert sucks too and I just sanded it down again...

I also fucked up with the el-cheap wood filler on the lock-bar holes....they just didn't stay there, I guess not enough support.

Will have to go back to bondo for the larger holes clearly but I really don't look forward to it. Bondo and I are simply not friends....

Good you post your screw-ups too, it's how we learn :)

Title: Re: Joust to Robotron conversion
Post by: Wurstkopp on March 05, 2015, 11:36:39 AM
One can is 15 Euros, wouldn't call it expensive but it's also money. I'll give it another try with more silver paint and without the translucent paint afterwards.

Indeed, amazing result for spray can......how did you get it so even ? I always have parts that seem covered better than others when spray painting large areas....
Title: Re: Joust to Robotron conversion
Post by: Wurstkopp on March 08, 2015, 11:31:02 PM
Thanksalot, guys, I'm really satisfied with the results. The trick is to be completely naked (high heels are okay), put some lipstick on and dance to "Goodbye Horses" while spraying. :)

Or you just sand it like there is no tomorrow, the more even the surface the better, put primer on, and then spray crosswise (use equal spraying moves and equal distances) while constantly checking from different angles. The more coherent the spraying moves, the better the results (it's a little like in Karate Kid). I think that one benefits from the solvents in the air to help relax. ;D

It looks very very nice !!!!!

Maybe a bit too shiny on the silver, but I'm quickly going to say that is AWESOME (those who will say that I only say so because my Q*bert is a bit shinier than original are dirty liars  ;D ;D ;D ;) )

No really it fits the theme perfectly.

There is one thing I wonder though.......what happened to the zero and the 8 ?
They look .......uhm......not entirely correct:

It seems they used pics of unfinished artwork. Don't think the upright version artwork on the second flyer got ever produced.

The finished artwork of the US-type upright machines looked like this:

Good work on the Robotron!
Glad you got the pcb working.

I bought silver paint last week (actually called aluminium).
Already tested it and it is really shiny too. Maybe a bit too much for my taste.
I might go for a light grey instead. And still haven't decided if I will keep the sideart and touch up or re-stencil. Hmmm..

Oops! Noticed a flaw in you otherwise perfect sideart :)

The blue is supposed to be a single solid block, with the red lines painted over it.
You have 3 separate blue and red lines.
Not that it matters much, but I am just picky when it comes to those things :)

Here, look at the originel sideart on my cabinet (this is the nicest side, other side is pretty scuffed).
