  1. AOX DoubleTime 16 - Info needed

    Got a picture of the card? Drivers for some accelerator/video combos were interchangeable. Seeing what this actually looks like might give a hint to what software might work with it.
  2. IIci processor replacement

    You should do, just to be sure nothing is shorting out. You want to use fresh solder anyways for putting on a new chip.
  3. IIci processor replacement

    On my board it was indeed the CPU... quickly replaced it with a spare 25MHz one and it is back in working state again - never had a dead 030 up to now. This is how you want to do it: https://www.youtube.com/watch?v=6PB0u8irn-4 Flat tip, a lot of flux and not using too much solder (or go straight for solder paste) help a lot.
  4. IIci processor replacement

    This makes me remember my not working IIci board. It has some traces eaten away and I repaired the broken ones I could find already. After this it turns on and is just sitting there - no chimes and nothing. After reading that your board works with an accelerator I did try the PowerCache as well as the Turbo040 in my board and low and behold it did boot up just fine with either accelerator. So it seems my onboard 030 seems to be stuck as well. I went ahead and removed it. Turbo040 and PowerCache still boot the board even without original CPU. I would guess the Micromac works as well without the original CPU.
  5. IIci processor replacement

    Not sure about the Carrera, but the Turbo040 does run with the original CPU removed or disabled (at least in the SE/30 - it should do so as well in the IIci) Chipping the IIci to 33MHz is not possible I think. For the chipped off solder pad I would just go with a tiny jumper wire once the new CPU is in place. You have a via right there so should be easy.
  6. SE/30 SCSI Not Detected

    Check the term-power fuse next to the SCSI port first. It can blow easily when devices are attached or detached while the machine is running. I had a board that would only see SCSI devices on the internal connector when a terminator was plugged into the external port. This resulted from a blown fuse as well.
  7. Quadra 700 Speaker.. specs?

    IIci is 8ohms and 0.5W with a 9cm*6cm chassis. Not what you have been looking for but if someone has a Q700 speaker we have at least something to compare it to
  8. You might want to also have a look at that: C10, C12, C13 leak heavily onto the UE13/UD13 area. Check if those logic ICs are still good. They tend to fail due to cap goo which results in all kinds of weird power issues, like the machine won’t power on or off, won’t stay on, etc.
  9. SE/30 video issue that has ME stumped!

    It may be the clock line that is the issue here. When testing my multiple card setup I got noise on the screen that looks similar to what bibilit posted. It also comes and goes when CPU load changes. I narrowed the issue down to the clock signal bugging down when three extension cards are installed. So the issue might as well show up in combination with PDS cards. If the clock output is weak or there is high resistance in the line somewhere the video signal will start to act out just the way as seen here.
  10. I also did some extended long time testing running both systems for a few hours. The Asante->PowerCache->Micron setup is wonderfully stable. The Turbo040 however has issues with running stable as soon as it is not the first card in the stack. So we are left with the tall card as the only option for the Turbo040. Ethernet and IIsi Pivot stuck on top of the Turbo040 runs like a champ and has been stable for a few hours. Did I mention the SE/30 is awesome with a 40MHz 040?
  11. I contacted one of the seller/manufacturer/whatever with minimum quantities not in the thousands on alibaba. Let's see what they say.
  12. If you do not plan to add another full size card to the stack you are good to go with the tall card. This will also let you use a IIsi Pivot as a future add-on with the 040. For the MacConTopper the following cards have been tested so far (I assume you always have the MacCon connected below the adapter) Micron XCEED Color 30 030: ok 040: not ok Kinetics/Shiva/Excelan Etherport SE30 - dual NIC SE/30 router anyone? 030: ok 040: ok Radius IIsi Pivot 030: ok 040: not ok The tall form factor will let you use two PDS cards connected directly to each other which seems to be important in the case of the IIsi Pivot in combination with the Turbo040. This however rules out full size PDS card as a secondary choice. I would guess that most of the other full size video boards like the Lapis or Radius cards are not 040 compatible anyways.
  13. As said I decided to make a tall version as well because the IIsi Pivot can not be made to work together nicely with the Turbo040. There seems to be a timing issue that does not occur when the PowerCache is used instead of the turbo. Problem also does not occur when the two PDS cards are connected directly to each other. So: MacCon->IIsi Pivot->adapter+Turbo040 = works IIsi Pivot->MacCon->adapter+Turbo040 = works adapter+Turbo040->IIsi Pivot->MacCon = works adapter+Turbo040->MacCon->IIsi Pivot = works MacCon->adapter+Turbo040->IIsi Pivot = does not work The GAL is buffering the clock signal and introduces a really small delay which seems to be enough to throw things off for the Turbo040 as it seems to be operating on a tighter timing than the PowerCache. And even though this... ...might look funny it is not actually useful I went ahead and just made the base of the adapter longer to go with the traditional route of putting things into the SE/30: The IIsi Pivot and MacCon will still fit nicely on top of that, so no problem if you do not need to run big cards like the XCeed. The Cache slot is moved a little bit more towards the back of the machine than on the TwinSpark, so the Turbo040 will fit way better as its heatsink will not be coming so close to the tube anymore. It will also have the option to apply external power for the cache slot so you do not overload the PDS slot on the SE/30. *and now that I think of it there is a lot of unused space - might as well throw a 12V->5V stepdown converter on there. The 5V line is bugging down quite a lot under the load of three cards. Measured 4,7V and 12,7V while running on a non-recapped PSU. A recapped one looked better though.
  14. Well... like not too much I guess. Will have to do a calculation after knowing the first demand. I have a TwinSpark-like taller version on the way as well for people who do not have a MacCon or do not want to modify it with a right angle connector. After adding up parts (those Euro DIN connectors are expensive ) and adding in some beer money (cards will be put together and tested by me - demand is hopefully not going to be in the hundreds ) we will end up in the $60-$70 ballpark - but really depends on how many I make at once and order connectors for. If you want one send me a message which one you would like (MacCon topper or the taller DiiMo-style) It is going to be a while before those are ready to be shipped out since testing is still going on but I can already start to scratch together some money then for ordering parts
  15. Alright, so here we go... I designed the card so you can choose between two main configurations. One will lay out all signals the way they are found on the single GAL Daystar IIsi adapter. The equations for said GAL had been found out by Joe in the old thread. The second configuration will put the signals the way they are on the DiiMo (or Artmix) adapter for the SE/30. I took a guess on the code for the GAL and it seems to work ok for now. The goal might be to get the best out of both worlds and fuse this into a single GAL solution. The schematics Joe buzzed out have been correct - using just an accelerator worked right out of the box. Using only PowerCache or Turbo040 works fine with the Daystar setup. Having the MacCon stuck into the bottom of the stack with the adapter+accelerator on top is working fine with both PC and T040 as well. Having a second PDS card on top of the whole stack is where things start to get ugly. Putting in the IIsi Pivot gives garbage on the CRT while the Mac itself still works and even boots fine as seen on the external screen. This seems to be related to the clock signal not being able to drive all the loads that are connected which messes up the timing for onboard video. I figured that with the DiiMo setup at least the clock signal has to be buffered by the GAL. Not knowing what is going on with the other two signals going through the GAL on the DiiMo I set them up to just get buffered as well as a start. I was surprised that it might have been so easy... The DiiMo configuration worked right away now with the Pivot, however only when using the PowerCache. The Turbo040 won't even POST now with two cards stuck in (it did before with the Daystar config) Just along the way of fiddling around with jumper wires on the several signals which are broken out at the PLD sockets I discovered that you can run the whole thing without having any GAL at all. You can run at least one PDS card and an accelerator in the SE/30 using only a passive adapter. Both configurations (or should I count the passive mode as a third one?) seem to work with different variations of PDS cards and accelerators and some combinations are not running super stable. I hope that we can find a setup soon which is running two cards and an accelerator reliably. The next steps for me will be fiddling with mixing the approaches of the Daystar and DiiMo adapters. *bonus* I know what you have been waiting for: It works and fits into the case
