Hi,
Please see some shots of my motherboard as requested in the falcon 030 Facebook group. The board definitely has been tampered with. R222, R221, and R216 have been removed and there is still solder left at some of the IC pins (pin 16 U68 and pin20 U63). I'm assuming that this is a leftover of the RTC hack. Should I put the RTC hack back to make the board function properly? Also, I have no sound in both the headphone jack and the internal speaker - any clues on what to test to remedy that? Could that have something today with C92? Also, I'm planning to socket the Dallas chip and replace it, this one doesn't keep time anymore.
Thanks,
Thijs

Based on Mikros'website (mikrosk.github.io) it's a C-lab Falcon. It is however in a normal Atari Falcon 030 labeled case... Is that an anomaly?
Re: Falcon 030 700015-
Both the motherboards I have are not in their original cases. I think they're both from a music studio.
At the time it was normal to rack-mount ST/Falcons motherboards into 1U or 2U cases for music studio work and when the industry moved to PCs, the Atari's were sold off in the rack mounts with the old cases separate.
So you can imagine it would be easy for a company that had more than one to mix them up.

There's an internal speaker? I must be missing that on my board here. Does anyone have a photo of that speaker - where does it sit?

It 's attached to the top RF shield, to the left of the floppy drive.GadgetUK164 wrote: ↑Tue Sep 22, 2020 6:35 pm There's an internal speaker? I must be missing that on my board here. Does anyone have a photo of that speaker - where does it sit?

That explains it - I am lacking the top RF shield! I need to find where its connected and see if I can mount something similar elsewhere I think.DoG wrote: ↑Tue Sep 22, 2020 6:42 pmIt 's attached to the top RF shield, to the left of the floppy drive.GadgetUK164 wrote: ↑Tue Sep 22, 2020 6:35 pm There's an internal speaker?

I don't suppose anyone knows what impedance and wattage the original speaker is?

J12, it will be a typical .5w PC beeper. Most people just disconnect them as they are pretty irritating. I have a 4x 30m SIMM board in one of mine and just put a Piezo in there because the .5 watter no longer fits.

If you remove the paper label, you will see the original S/N.
