    Correct, nothing else on there, otherwise I would have posted a picture of the other side as well

  3. Maybe. Once the CPU heats up the maximum current it can drive will get lower. This is only a tiny little bit but as it obviously is operating at the edge of what is possible that tiny bit might be enough.
  4. That's what I am thinking as well, because in my experiments once you add a PowerCache to the mix the artifacts are gone. The PowerCache has buffers which most probably deliver more power than the bare CPU driving the bus on the stock logicboard.
  5. On the PDS adapter we made the clock signal is buffered and I still get the snow on certain card combinations so pretty sure it has to be something else.
  6. There clearly is corrosion on at least one of the RAM slots. The contacts on the first one look like they are green in one of the pictures. You can try to fix that with vinegar but RAM or ROM slots I have seen with this kind of corrosion have all been toast so far.

    Running 7.5.5 on my IIci and did not test the card any further yet. Do I already need the patch you posted earlier for 7.5.5? jt: That's an Apple 6100 adapter: 820-0515-A If you have a G3 upgrade then you have the PDS bracket which is different from the Nubus bracket I think.
  8. Lets see if someone based in the UK is chiming in here, otherwise send it to me if you want. Sending it to Germany and back is at least a little bit more cost effective than sending it to someone here from the US. I can test the LS166 at UE8 and the muxes and shift registers next to it as those fail as well sometimes and replace them if needed. Can you post a few pictures of those areas of the board?
  9. Help Testing SE/30 ROM?

    Just checked, mine shows up as Futura II LX/DSP in Tattletech. I can‘t get the CP to load though. Whenever I place either 3.5.5 or 3.5.6 into the system folder the Finder will crash hard on startup. Resolution switching also does not work. I might just have to get out a different adapter for that... this one is supposed ro mimic a multisync display but you never know how well non-Apple cards pick up on the sense line magic.

    The TI chip on the Formac card is a video system controller. http://www.datasheetarchive.com/pdf/download.php?id=264c504fc8606c3fbde0e44123b15a45d8d06c&type=M&query=TMS34061FN The TI chip on the Lapis board is a RAMDAC, so the video controller must be implemented in that Xilinx FPGA. A lot of graphics cards used FPGAs as the video system controller I am pretty certain that this card is their original design. Also it does not seem to need any drivers as it is not accelerated anyways. You can switch resolutions on some old Formac cards by swapping in different ROMs (at least this is how it worked on some of their Nubus cards for their line of fixed frequency CRTs) SwitchRes is not going to help me here I think. Apart from that 1024*768 is pretty impressive as a secondary display next to an SE/30 anyways. While we are at it I just got another delivery with some cards I snatched: We have another Formac card right there together with its manual. Then there is some E-Machines graphics card - it must be a Futura II I believe. The Asante MacCon is going straight to their 20 brothers and sisters piling up in the random Nubus cards box. What is particularly interesting is the other NIC in the lot. It only says "EMacIIc". Google throws out that it was made by CELAN Technology Inc. Never heard of them before. Finding drivers for this thing is going to be interesting...
  12. One can clearly see that there was a cap installed. Its legs are still there but it must have fallen off the board (or got knocked off when inserting the ethernet card) You want to put one in again when you do the recap. Also be sure to wash the board really well... lots of residue between those IC legs. Jumper wires are common on old hardware. The one on your ethernet card looks factory installed. I would leave it there.

    And it works... It is putting out 1024*768*8bit@79Hz which my old Compaq 8030 has no issues syncing to. The monitors control panel also offers 1024*928. The card will still output 1024*768 but you can pan the display up and down whenever the mouse arrow hits the top or bottom of the screen. I know this mode from Formac PCI video cards already but quite surprising it already existed back then.
  14. Now that's even more interesting then. With those two cards plugged directly into the logicboard I never had any issues so far. Might have to give it another go with adapter without accelerator and two cards to see if I can find a cause for this. It has to be something VRAM related. I suspect it might be the data lines being too weak to saturate the inputs on the VRAM. If it were for the address lines there would be more things going wrong and the artifacts would form more harmonic patterns. It might be worth checking how D24-D31 are connected on the PDS cards ie. if they are buffered or not.
