    Coolest thing I've found this year

    That mouse has a nice feel for righties and I have never seen an optical one. When I worked for the empire I came away with a clear (roller ball) version of that mouse and the shape that proceeded it. The latter even has an adapter that takes if from serial to PS/2.
  2. The first Mac that I purchased was this iMac 4,1 which recently had its drive die. Today I got that drive out and soon it will be replaced by an OWC SSD:

    IIci with a Radius bonus!

    Very nice. A IIci is next on my list. I have one of those Daystar 601 accelerators and my chances are better at getting a nice IIci then the unobtanium IIsi daughter card to run it in my IIsi.
  4. Acard AEC 7720U card is what is shown. Here is what is available on Ebay At some point I'd like to do a bake-off between that card and my SCSI SSDs when time allows... Great progress on conversion and thx again for the how-to on the circuit. I am trying to follow along with your comment about grounding. The stock SeaSonic has ground enter the chassis from the power plug which has the ground wire grounded to the chassis with that metal bracket that surrounds the power plug on 3 sides and is screwed to the chassis with one of the 5 screws in the bottom. The other 4 points where the SeaSonic board mounts to the chassis are the remaining 4 screws that go into the stock standoffs. Of those 4 mounting points, 3 appear like they should be ground as there is metal, that would be top left and both on the bottom of this photo: What my harness did was ground those 3 points along with the power plug. Are you saying that only one of the 3 with metal is actually needed to ground the board? I did not test this, I just mimicked the stock setup which may have been overkill.
  5. @superjer2000 exceptional work and exceptional timing. I will follow your lead when time allows. Here is the progress I made today on getting this running in my IIsi. I had mocked up the fit with a piece of ABS plastic however I was concerned that the board was not grounded to the chassis. This is the bottom of the SeaSonic: 3 of the 4 mounting points look like they were grounded to the chassis so I created a harness to do this so that I didn't need to drill any holes into the IIsi PS chassis. This is the grounding harness next to the ABS: The harness goes under the ABS next to the bottom of the chassis: Above is a pop rivet about to be set in one of the existing IIsi PS chassis standoff/risers. Here is the harness with crimp-ons bent to 90 degrees so everything will fit: I hot glued some washers to the ABS to ensure crimp-on O would have good contact to the bottom of the SeaSonic: In above photo, bottom right corner of the SeaSonic does not have ABS underneath it so it just has a screw screwed into a riser with its male thread post filed off. This is where power enters and it is surrounded by the metal that is secured to the floor of the SeaSonic chassis. In the IIsi chassis, the plug is rotated 90 degrees and I riveted a male tab through the mounting hole and covered the bottom with hot glue for a bit of extra protection from it shorting something: And here is the plug installed in the IIsi chassis with a female crimp-on as the last connection on the grounding harness: THe fan is now installed with automotive trim double-stick tape and it is not going anywhere. Here is the unit installed showing the 4-pin molex exiting the chassis cover and powering my IDE SSD: I let it run for about 3 hour and I put a bit of a streamer on the back side of the case to see fan activity. It came on after about 15 minutes and appeared to run the entire 3 hours. I left several times and it was always blowing when I returned. When I touched the top of the case it was barely warm. Next step is to build that circuit!
  6. I thought about that too. While certainly doable, I think there'd be a bit of work to get it functioning like the stock PS. I suspect that the power socket for the monitor is not hot until soft power is enabled. I don't know how to wire that up. As to the fan...that probably could go at the other end of the PS chassis and blow on to the innards. This is still a work in progress...
  7. Being that there were no instructions in the SeaSonic box, I was careful when approaching the heatsink. I was pretty sure I'd be OK as the heatsinks all come in contact with the top of the SeaSonic chassis. As to what is missing... Above is the back of the stock IIsi PS. When I put the SeaSonic in the IIsi chassis, the power plug from the wall goes in the male connector on the left. The fitting on the right is not used and that is where the fan blows out. I believe it is for the monitor so that it will turn on with the IIsi soft power. I never had that power cord for my IIsi. I don't feel this is a big loss as that fan needs somewhere to vent the heat and that opening will work nicely. This is what it looks like from the back of the IIsi case outside looking in...
  8. I spent a bit more time with this. I didn't have enough standoffs so to mock this up, I used a piece os ABS plastic and riveted it using the stock standoffs: The 3 holes in the plastic are where the PS will be attached to the plastic. The SeaSonic power connection slots into the stock chassis nicely. Here is the PS screwed into the ABS plastic, notice that it hangs over where the wires exit the chassis to join the mother board. For now, I just have the fan secured with craft double stick tape. When it comes time for final assembly, I will use some very sticky 3M automotive trim double stick tape. And here it is installed and running: All unused wires have been removed from the PS and the green PS-ON is grounded in a now-unoccupied ground position. I plan to keep the 4=pin connector to power the hard drive and fan. These will feed through a hole in the chassis cover. There is plenty of room to put the chassis cover on, however, I'll do that after the soft power circuit gets built. FWIW, with the PowerKey init installed, it does truly shut the machine down as it does with my SE/30 which does not have soft power. After running the in the configuration shown (nothing in the PDS slot, stock video, and IDE SSD+Acard SCSI-to-IDE bridge) the fan kicked on and ran continuously. It has been in the low 80's in the Seattle area so it was hot in the office. While I have no way to measure how hot the PS was, those 3 silver grids were quite hot to the touch. Yes, going this route will lose the plug for the monitor however I never had an Apple monitor, just my Envision LCD...

    32-bit Clean ROM

    Good to know. One of the SE/30's is getting the on-board 50mhz installed soon so I will look for that setting in the DayStar CP.

    32-bit Clean ROM

    Gamba2 documented the SIM chip numbering here I used this when I was sorting through my stack of SIMs in June: Top 3 are all IIfx per chip numbers and tattle tech reporting 32-bit clean. The top left does not boot...does anyone know if a SIM can reflashed? Here is the back of the SIMs: When I boot to the IIfx SIMs I get different artifacts...here is one: And the other: The machine has 128MB RAM so it takes some time for the RAM check to complete. I'd love to find a way to skip this but I don't think there is unless you are using a ROMinator.
  11. Good news...the SeaSonic fired up the fully loaded IIsi without issue. IIsi PS chassis is gutted other than the wires in from the SeaSonic. I left the green PS ON in its ATX location and jumpered it to ground (you can just see the "U" made with white wire): I have the PS plugged into my PowerKey switch for my SE/30 and it is then plugged into a switchable strip. When I power the strip, I can turn the IIsi on with the ADB KB Power button. When I try and shut down, I need to hit the switch on the the strip. I do not have the init installed for the PowerKey and I don't know whether it will work here. I ran the IIsi for about 30 minutes and the picture looked better than it ever had. It used to have a slight flicker on the 15 inch LCD. Now it is rock solid. The SeaSonic fan turned once when powered on however I did not see it spin while I used it tonight. I will keep my eye on it... I am looking forward to seeing your progress on the circuit. I will likely follow your lead.
  12. THx for this @superjer2000. There is a daughter card that can be seen on the left side of both of my last photos. I wonder if that board could be salvaged and used for what you describe.
  13. The plot thickens on my attempt to put the SeaSonic PS into my IIsi chassis. As I was removing the stock wires I noticed that all 10 of my wires are filled. The photo shows the ground removed from position 5: Here +5 red (position 4) and ground (position 5) are removed. Now there is a clear view of position 9 with a blue wire: Diagram from this post has position 9 empty. I have googled for a bit and even tried to fetch this from the way back machine with no luck http://www.xlr8yourmac.com/systems/MacinPC_ATX_case/images/PC-MAC_PS_pinouts.jpg´╗┐ Does anyone know what position 9 might be? THx
  14. Yes, ATX12V Flex/Mini 1U This is the description on NewEgg
  15. Exciting times. My 2nd SeaSonic PS arrived today and is on its way into my IIsi: Stock entrails are on the left, SeaSonic out of its case are sitting nicely within the top part of the IIsi PS. My plan is to remove the stock entrails all except the plastic molex connector. I will remove the original wires and then wire directly to from the SeaSonic with no splicing required. While I could easily find a PS switch that would fit in the monitor power port at the back of the case, I'd rather have this work like stock with the power button on the keyboard. I get how to run the wires from the PS to the plastic plug. What I don't get is how to pull this off: Here are 2 images from higher up in the post: Can someone please explain to this non-EE exactly what I need to do enable the diagram on the right? I don't get what connects to what... THx!!
