missing volume pots? can't tell from your pic, they're located at header J2 on smash tv and P4 on total carnage. If you don't have these i can make them up for you but it will be about a week or so until i get more pots in.
 
i have a volume pot for the smash game and have moved it from board to board...will the game not boot up without it connected?
 
it'll boot fine without the sound pot or without the soundboard, you said you got no sound tho "playing in mute" your sound pot wiring is 3 wires correct not 2?

a smash tv pot will work on total carnage but a total carnage pot will not work with smash tv unless you add the shield wire.

maybe you hooked the ribbon cable up backwards? (red trace should be at pin 1) when you do a sound test do you get IRQ ok/functional?
 
power cable to the sound board not correct? I think smash tv power cable is different than nba jam or mk2. I know nba jam and mk2 are different.

he could have gotten them mixed up probably, and yea the total carnage one is the same as MK1/NBAjam/T2 (excluding t-unit)while the smash tv requires the extra -5 wire. mk2 tho is definitely the odd one out (tho it might work with revolution x, haven't had one of those yet).
 
i have the cables that came with both...ill picture them tonight....i might have had the ribbon cable on backwards after it came back...

originally when i got the pcb set from ebay the roms booted fine but i had no sound...bad cmos detected. I could play fine with the boards connected in my smash cabinet....

i sent the total boards including sound without the wiring harnasses to eldorado..they supposedly fixed the main board...replaced custom 99 chip that was bad...and fixed the sound board

when i hooked them up first time i got no picture or sound....then i connected the volume pot from my smash board and i got some popping noises and no boot up rom check..so i turned the game off and disconnected the top harnass (power to the soundboard) and the game would boot...obviously with no sound

am i missing something or do i have a short somewhere maybe that is making my video not display when my sound board is connected...

my sound post is a 3 wire...one red, one black and one small strap
 
ah ok, check your voltages mainly your 5v (it should be around 5.10-5.18v)

if you decide to up the voltage be very careful as if it's an old power supply it could spike and blow your board. (sorry just have to say this)

that sound pot and wiring will work fine with both boards as long as all the wires are making proper connection.

from the sounds of it your issue is more of a voltage thing and i would look there first.

edit: for the hell of it you can check the solder side of the boards for touching pins (probably in the sound board) as they can get bent easy and short out to other pins/traces in shipping/reinstallation. also make sure all your chips are fully socketed as those can walk out in shipping/movement also, i'm gonna bank on voltage tho and if that's not it concentrate on the soundboard as that seems to be where your issue is coming from.

let us know.

will do...i turned the voltage down after my last main board quit on me thinking it might be that....the smash board works great and measuring it on the 5v spot at the top of the board i got 5.14..the last owner had it cranked up to nearly 6...

i was thinking the same thing about the socketed chips..i have pushed on a few....since it only flakes out when the top harnass is plugged in i was thinking a short on the sound board somewhere there...will check power +5 tonight on total board and inspect the sound board again

thank you guys again...i wanted an arcade but didnt realize how much fun/trouble it would be maintaining one

in my area getting someone to work on them in your home is just not realistic
 
First off I want to say ty for all that helped.

Ok home now from the daily grind...GOOOD News...

I tried pushing chips in and checked all connections. NO dice.

Then after thinking about the problems I was having I checked the voltage output on my ps. At the ps it was right at 5. On my smash board it comes out 4.8. Smash works fine.

On total board it regged the same but when the sound board is connected you get nothing. When disconnected nothing worked on screen, just monitor noise and marquee. So I decided to up the voltage with the pcb disconnected. Man does it fly up quick. I upped the ps to 5.19 on the 5v terminal. Measured voltage at the board. wooohooo 5.0

Apparently total takes more juice and is much more voltage sensitive. Sounds and play are great. Now just to cap my monitor. :)

nice so it was a voltage issue?

if total carnage is taking more juice than smash i would try cleaning the edge connector on the PC with a pink pencil eraser. make sure and blow any and all shavings off the board before power up. sounds like your connector is dirty causing a higher voltage to be needed.
 
ty will do..mike is adding pin 25 to my splitter so im guessing voltage will come into play again here soon..amazing you guys asked about it first...my eldorado guy assumed i blew the board by some nonsense...i am pretty sure my new game told me i sucked when i let the guy get killed love this pleasure dome

yes....i turned my smash down without checking it after my new total board blew.....looks like total is very finicky...smash is not...both work great now manually...waiting on my modified mikes double...hes modding it personally for this ...

...So I'm curious, you are talking about Mike's Arcade Double Jamma correct?:

What is the modification related to pin 25 required to make that work?

Looks like pin 25 (& cc) is for player 1 or 2 fire button 4:

Please post pictures of the modification, sounds like I might need to do the same...

I also have a couple of these 2 in 1 Jamma switchers:

If I counted the traces correctly (lol), it looks like there is a connection for pin 25 - I wonder if this one will be easier to get everything running? Mine has one of those lame remotes, but looks like there is a solution coming soon from DogP ;) : http://forums.arcade-museum.com/showthread.php?t=264934

I have a Smash TV I still need to get my Total Carnage board installed with the 2 in 1 setup. I have both styles of switchers, just wondering which one is preferred/easiest to install everything?

Also, please post pictures of your added PCB mounting & harness routing...looking forward to seeing this....great work!


WooHoo!

will post em gack.

mike is adding a 25/c trace for me--his double jamma does not have one. smash and total use a jamma + set up ...on jamma alone 25/c is listed as nc...not used---after emailing him he didnt even know this was a problem, then after i showed him the pinout he was very willing to help me...i didnt want to hack his harnass up---i still either need to split my volume controls from one pot or add a second..i will most likely add a second and put the volume pots on the service switch mount

here is a link how this guy did it

im gonna do a mikes with a button also just my take on it...will post the redo as i undertake the project. i am adding a marquee and a button to switch the games so like this guy said if both players hit bomb or need to restart after dying to continue play the game doesnt switch between smash/total
 
Don't think this was one of the problems but a buddy of mine had a similiar issue with the sound not working. He purchased an extra sound pot with cable online, I think it was even from Bob Roberts if I am not mistaken. Anyway the problem ended up being the sound pot and connector pinout was incorrect. I think it may of been different than other Midway boards. Glad you figured out the voltage problem, Midway boards are infamous for not working properly if there voltage is ever so off.
 
My double adapter is due back this week and I was looking on ebay for total carnage items and I ran across an item that made me second guess the volume pot. I have been able to use my existing pot for both boards, but one for sale on ebay suggested that total carnage only uses two of the pins and wire positions, whereas smash tv uses 3 pins and all three wire positions.

does it hurt to use the smash pot on total carnage?


and does anyone know the specifics on this pot to make another one?

or can I just splice the wires and use two connectors and one pot?

thanks

Post 4 of this thread i mentioned the number of wires.

no it won't hurt using the smash tv pot on the total carnage
 
More in my double jamma saga. Mikes board just came back today with the trace wire added.

One problem-I sent him the extender harnass back and he sent it right back without a wire for 25/c---again arggg

Nothing is easy for me.

Here's both boards in the cabinet and mikes above them

IMG_9459_zps57407091.jpg


So after I hook them up...nothing. As I suspected mikes board dropped my 5v at the main boards. After checking my 5v dropped all the way to 4.4. So after slowing upping my volts I was able to get both boards to work at about 4.9

Then after testing them, my smash board worked fine with its new wiring...little loud with only that one pot and total worked but no right action and hard to hear. Volume pot is going to be added later
 
looking good keep up the good work!

sucks about the extension harness. :-(

I know it's pretty much definitely the extension harness but have you tried cleaning the edge connector on both boards with a pencil eraser??

also you might want to get some deoxit to clean the actually wire side edge connector on the harness, this game is really old and mine can be flaky as well sometimes with the power (caused by the old oxidized or tarnished pins). Just an idea.
