    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    Damn, the USB device isnt being seen by the system at all to even install a driver. Somethings up with that. I only have one micro USB cable, it may be a charge-only cable. MicroUSB isnt something i keep around, i have a ton of miniUSB cables, and a few USB-C cables but coming up short on Micro.

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    It must need a driver... I need to figure out what driver.

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    I will have a video out tomorrow on my channel, within that video demonstrates the fault, the video would better explain whats going on than I can in text. To make a better video, i decided to test the WarpSE against the Radius Accelerator 16 and the WarpSE actually stands right up to it, and...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    Too many questions bombed at me at one time so my brain.exe process died. Sorry... What I can say though is, I only tested the sound control panel as I have no other software handy to test (Im not a gamer so i dont have anything like that handy). I have a MOD player somewhere but i think that...

    WarpSE: 25 MHz 68HC000-based accelerator for Mac SE

    I did a quick betatest and benchmarks on my SE. My results are impressive so far, with a few caveats: As far as raw computing power/benchmarks, its impressive. Speedometer shows results that even beat out the 68020 Radius 16 that I have. (Except the floating point but thats expected)...

    Question(s) with my first brand used SE/30, hopefully a restoration story...

    That looks like noise getting into the vertical deflection circuitry. The original IC failed for a reason, and I think you are witnessing why it failed. The problem is going to be how to figure out the actual cause. Perhaps, you could use an oscilloscope to probe the vertical drive signal into...

    ADB KVM Switch - Thoughts?

    What would be awesome is if this worked like with some sort of IP KVM (which i think is also based on the raspberry pi) so i could just connect into a Macintosh from a modern machine (Such as my main machine into a bridge machine) Looking at the PiKVM project: https://github.com/pikvm/pikvm...

    Powerbook 180/180c Termination power mod

    This is probably applicable to all the other Powerbook 1XX machines as well as there are little variances between them. I took a gander at the 145 schematics and the 180c is basically the same in this department. The key here is to attach a shottky barrier diode much in the same way you do on...

    Of course i had to be the lucky one! On the 540c, i dont know yet. it could even be the rear polarizer film, its not the front. I just cast it aside to figure it out another day.

    I have a 540c which has a weird halo in my junk horde as well, I never took it apart to figure out why that was yet or tinkered with it.

    But it centers around Hoisden. That's the common denominator here. What can be different between them and every other LCD manufacturer? Thats whats going through my mind at the moment. Theres a lot of process variations, sure. but idk what to think anymore besides that.

    Yeeaahhhh thats what i suspected. Its looking more and more like a defective chemical mixture.

    Did Hosiden make that one as well?

    Yeah the yellowing is normal as the UV and heat from the CCFL affect the diffuser light spreader thing. A lot of my laptops are like that now.

    Macintosh Portable horror story

    Funny you mention, I have a 180 thats starting to tunnel. It didnt when I got it over 10 years ago, and its been stored in my climate controlled house ever since. So yeah it might be a factor in potentially decelerating the effects, but it will still happen regardless. I do think its a bad...

    Hosiden is just shit, they do not hold up to age.

    Probably, I forget. im at work and the machine isnt in front of me but it suffered from tunnel pretty badly. I bought another panel on ebay and it had the same problem plus ribbon delamination. I used that one as my baking experiment. Failed.

    See thats what I thought initially, but in this case it isnt. the drive electronics/inverter were made by hitachi, but the glass panel itself was made by yours truly, Hosiden (only in a few models, the 750c being one of them)

    Well, it didnt work on my color panel. I baked it twice, one I left it in the oven all night long. Ran my electric bill through the roof, and no change in behavior. It might work fine on black and white panels but not color. Since this seems to be common with the Hosiden brand, I have an...

    Its all of those Hosiden panels. They all do this, I have Hosiden color panels in my Thinkpad 750C and its the same thing. Tunnelvision.
