Just picked up a DD, and I have full sound, but no speech.

Looking for a sys80 pro to walk me through doing a sound/speech diagnostic on sys80A.

I have a manual -- it sounds like -- it's test 17? But not sure how to manage it exactly.

Do you have any other walking sys80/a games? Easiest thing is to try swapping the speech chip

I have a Black Hole.
Which chip is that?

Can we start with speech test? How is that run? I see a black button to press too - wondering how that works.

I found the test for a6

If I press the self test button once, it says ah. Press it again

Press it again makes a tone

Shrug seems correct?

I've never had a game with working sound to compare and my BH had a ni-wumpf mpu so I can't really say about the test. When I was trying to fix my speech everything basically said that the speech chip was the only thing that was ever really at fault since there's pretty much nothing else to the speech circuit.

The chip is U14, an SC01. They haven't been made since the 80s so they're pretty expensive if you can find them on ebay or anywhere, but if you can swap from another working game that can confirm pretty easily.

Yeah good call - swapped chips and no change. Black Hole still talks, and DD has no speech. Hey at least I'm not out a $65 chip... whew

Next idea?

Have you checked to make sure all your sound select lines are operating?

Also check r16, it's the volume adjustment for the speech

I found this on a Sys 80 repair site while I was looking for my sound issue.

Chances are your SC1 speech chip is toast, but not always.. This is the worst situation since you cannot get this chip anymore. Search for a new board on ebay or where ever.

To make sure, get out your scope and be sure that the analog signals and amps are working correctly. No output to the main amp probably means you have a bad (or missing) SC-1 in the lower left corner of the board. The output from the SC-1 goes directly to R16, so test that. It then goes to the main amp with the normal sounds.

I just swapped it with the one in my Black Hole SC-01A is fine.

Oh, I'm sorry, I should have read your responses before copy and pasting.

I'm new to troubleshooting sys80 so the most basic of tests or checks is beyond my skill set -- so looking for the easy stuff to try next.

I'm the same way. My issue is near identical. I have background music but no sound effects. I replaced the RAM but it is still not working. Let me know if you find something out, maybe it will help me.

Hello,

check the dipswitch number 6, it must be ON to enable speech.

Check it with ohmmeter to be sure it works !
