Firepower speech problem

[Andy_B]

Just picked up a project Firepower. It was missing the speech board which I have sourced with original FP speech ROMs but can't get any speech.

Originally the problem was that the sound board worked fine on its own but would produce no sounds at all when the speech board was connected. I found that W1 was installed which I understand is for sound only. I clipped W1 and now the sounds play with speech board connected but no speech. All the other jumpers check out OK.

I replaced the original Scanbe speech ROM sockets and buzzed out all the connections. Similarly there is continuity on each side if the ribbon connector. Dip switch 2 is on and dip switch 1 is off which I believe is correct - in any case any variations in the dip switches don't produce speech.

I'm a bit stumped and would welcome any suggestions.

Sounds like the dips are correct too. Your jumpers correct?

Sounds like the dips are correct too. Your jumpers

How can I tell whether they are 3532 or 2716 EPROMs? They aren't marked as such.

So I found the reason for no speech. Blackout speech ROMs fitted

New speech ROMs burned and fitted but still no speech.
Fitted new speech ROMs in the correct sockets () and all sorted.
