Help identifying the upgrades on a Falcon.

[AndresPlazaR]

Hello!

I'm finally the owner of a Falcon, and I'm very happy. The first impression is that the machine is working, so that's nice. But when I opened it, I found 2 upgrades that I cannot identify:

First one, I think, it is a buffer patch. It has wires going to the floppy controller (pin 14) and to the motherboard.

Second one, has wires connected to both EF68B50P ICs (pins 3, 4 and 5) and other places in the motherboard. It has some oscillators, so... It is some kind of overclocking? The strange thing is that there are other cables coming from the little board, but they are cut. And, of course, there is the fact the fan was removed to put this little board.

Any clues?

Thanks,

Andres.

Thank you so much! Yes, searched for Nemesis and the same card showed. :-)

Hi Andres,

Well done for finding a nice Falcon! You are lucky to have the Nemesis bus accelerator, it makes the Falcon so much better to use and enables much higher resolutions in true colour if you use Videlity or Centscreen etc. Just remember you need to have the accelerator enabler in the AUTO folder for it to enable.

The Nemesis indicator is a very good tool.

Thank you for those tips, Steve!

Steven, actually I have one question: the Nemesis indicator that you mention, it is different than the "accelerator enabler" you mention first? If so, do you know where I can get the accelerator enabler? The Falcon did not come with a diskette with it.

Thanks,

Andres.
