@marbosar77 I'm pretty sure @HigashiJun linked you to a suitable oscillator above ^^^

Re: Falcon FPU overclock PCB
Then just do not butcher your future Falcon with all the mods you want to perform, unless you have good soldering skills and dexterity.
That would be a pity...

@HigashiJun that's why a friend of mine will do it :roll:

Re: Falcon FPU overclock PCB
@marbosar77 since you are new to all of this... my advice would be refrain from actually doing anything. I mean sure, buy a gotek, SD2IDE, new RAM, whatever but stuff like clock patch.. .that's a mod for someone who knows what he is doing and why.
Wait for you Falcon, play with it, diagnose its faults (if any) and only then start looking for possible modifications.
Accelerating the FPU alone may, in extreme cases, make your Falcon incompatible with some time-sensitive demos for instance. Same goes for various DSP and/or CPU acceleration mods.
The only reliable way to upgrade your Falcon's "stock speed" is the Nemesis or Phantom and that requires even more complex soldering.

I agree with this. My Falcon doesn't actually need the clock patch at all.mikro wrote: 16 Jan 2024 09:44 Wait for you Falcon, play with it, diagnose its faults (if any) and only then start looking for possible modifications.
I'd do as little to the machine which requires soldering as possible as they're old and fragile machines.
As for upgrades, if it doesn't just fit onto the CPU upgrade header then I'd not consider it.
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

Re: Falcon FPU overclock PCB
I guess @marbosar77 will at least have to replace the RTC chip which must be dead by now if not already replaced.

Re: Falcon FPU overclock PCB
True. That's the only thing I replaced, using the Exxos one. You need a good desoldering gun and technique to do this due to the thick ground plain.HigashiJun wrote: 16 Jan 2024 10:26 I guess @marbosar77 will at least have to replace the RTC chip which must be dead by now if not already replaced.

I never use my desoldering gun (lost somewhere in my closet) but my trusty braid and flux.stephen_usher wrote: 16 Jan 2024 10:50 You need a good desoldering gun and technique to do this due to the thick ground plain.
Same was for the RTC chip in my Falcon which came off easily, apart one ground pin which required a bit of know-how I must admit.
