Hardware :
    My Falcon with the Afterburner in it
    (overclocked at 40Mhz with the bus at 20Mhz)
    and the Eclipse PCI adapter with an ATI Rage IIc video card
    (click on the photo for a biger view).
      AB040
        I'm using the AB040 for 5 years now. I had lot of problems mostly due to the fact that aparently mine is one of the first release of this card. I had to make a clock buffer (and I took advantage of this to overclock the whole thing to 20/40 Mhz). I use to have some instability with some version of the toolkit but I totaly redid the clock buffering using ABT component instead of 74Fxxx and I change the original 68040RC25 that was on the AB040 by a 68040RC33. My computer is now way more stable. I'm even able to start the Falcon at 25/50Mhz (by replacing the 40Mhz oscilator by a 50Mhz as mine is on the socket), but the blitter hangs before finishing drawing of the Atari logo.

      The ethernet adapter
        I'm using the cartridge port ethernet adapter with a genius parallel ethernet adapter from Elmar Hilgart. It's way slower than any ethernet card but a least it works (under Mint and Sting) and for now it's the only ethernet solution for a falcon. The only problem is that Genius discontinued the E3000II adapter (based on the RTL8012 from realtek) a few months ago. I was lucky to have one from a long time ago on an old PC laptop.

      The Eclipse
        I just add an Eclipse card to have good video perfomances. I'm using it in 1280x1024 in 65K colors (16 bpp). It's very fast (more that 2000% speed increase in comparison to a standard Falcon). AS the tk5.xx doesn't work on my Falcon I can't use PCIBIOS, so I'm using the Eclipse/Ati in the "old" configuration mode which is suppose to be slower than the PCIBIOS mode.

      Next
        And the top of the top will be the replacment of the AB040 by the CT060 from Czuba-Tech(Rodolphe Czuba).
OS :
      TOS
        For development (ASM, C, ...) I'm using the most stable configuration I have : old AB040 drivers, standard TOS (4.04) without any VDI accelerator. If I want internet access (I have ADSL), I'm lauching the Sting config with NVDI. Now that I have the Eclipse I'm mostly using fVDI/Eclipse with the TK5.xx AB040 drivers with all my configurations (dev, Internet, ...).
      MiNT
        For C++, Internet and fun stuff I'm using Mint 1.15.12 (040 version of course ;]) with the TK5.xx .
