Hi
I have a Hard Drivin upright that i am trying to restore
I now have managed to get the screen working (Intervideo chassis) - the issue where just some bad solder joints.
I still need to have the Red color fixed, and a new capkit.

Now i can see what the game does at startup, so before i put more energy into the monitor, I want to get the game working
When i power it on it first says that brake pedal is out of adjustment, but I can turn key to continue.
Then I get this message "ADSP timeout error"

If i look at the diodes at the PCB the most of the lights lights up, but no light in the middle PCB does not light up at all, and that is the ADSP board, if i test the 5V at the 5V test point at the board it is 5.3V

Things i have done
1.I have put in a new 10A power supply for the 5V, and adjusted the volts so that i have 5.3V at the 5V test tabs on the board.
2. Replaced all the caps on all the game PCB's -> my log can be found here https://www.dropbox.com/s/0n1nutecz4...0log.xlsx?dl=0
3. Cleaned all the socketed chips on the boards.
A note regarding the new power supply - according to the documentation i can find, there must be two sense wires (red/stripe and brown/stripe)
All my wires are red or brown with no stripe, so i have connected them all to the new power supply.

If I test the 12V at the testpoint at the multisync pcb I get 11.5V a little low - I do not know if the ADSP board uses 12V? - there is no 12V test points at the ADSP board.
Do you know where to look to get the ADSP board working, get the LED's to light up? - if you do give me a ping :)
Hi Per,
Hey ! That's a very interesting WIP that I'm gonna follow up closely, because I also have a Race Drivin' cockpit cab to restore :). Unfortunately, it is not stored at home but at a friend's warehouse :'(. Worse, I never powered it up ! So I have no idea if it works a little bit, or not at all...
I don't know at all the architecture of the Hard Drivin generation ATARI boards, so I'm not able to help you right now. It would be a good thing if I could find some time to study its schematics...
Regarding the power supply and its "sens" wires, personnaly I would have connected them. They are there to show the power supply what is the actual voltage being used, to let the power supply to slightly adjust its output level (it works as a voltage control loop). Since your modern power supply doesn't feature a control loop system, it doesn't make sens in my opinion to connect the sensing wires :).
I hope that others here will be able to help you !
Hi
Thanks :) - I hope that i can find out why the ADSP board is not working. =?=
My best guess at this time is to change the caps at the APU PCB - it gives the main PCB its +15V, -21V.
I do not know if the fault is at main pcb or the ADSP pcb.. but i am thinking that it is the adsp board, because of the missing led's
As I could tell the caps i changed at the three "game boards" where the original ones from 1989 - so It might be a good idea to change all caps on the other boards too :)
I have some more Documentation here if you can use it
Initervideo chassis manual: https://www.dropbox.com/s/kwo09b1czykv5i1/intervideo_vp_series.pdf?dl=0
Operators manual for the game: https://www.dropbox.com/s/divndktf7qchn6u/Hard%20drivin%20operator%20manual.pdf?dl=0
Well some status - it seems that i can test the ADSP board in the test menu, so i have tested it - but impossible to see anything without the red color.

So i think that i need to fix the red now :)
Another thing - after i have reset all the options in the menus i do not longer get the ADSP error at startup?!?!?

So definitely I need to fix red color now :-)=
Hi,
Wow ! That's great !! :-)=
There's possibly some kinf of CMOS RAM with the options stored in it, and reseting everything put it back on track ! ^-^
It's good to know that's something to do first :).
Thanks for the links to the documentation, but I do have the original Service Manual on paper ;).
Cheers
There is two MK48Z02B15 cmos/batterys who stores informarion.
Expected lifespan 7 years. I have orderd some new here
