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

    Only have a short amount of time to test right now (after work). "WarpSE.GW4410A.0.6a.exe" FIRMWARE: 1. No problem with the power-on test after leaving it disconnected for more than 4 hours. I've never had the bars appear once with this firmware! 2. I see 25MHz in Norton System Info, which...

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

    In my limited testing on my lunch break moments ago, I got the thick vertical bars at every single power-on with the 0.6d firmware flashed to WarpSE, which is bad. I then flashed 0.6a firmware, and at every power on I got a normal screen, which is good! But to make 100% sure "a" is really OK...

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

    Yes. Another reason I'm not a Windoze fan. Japanese Windows "/" chars (in a path) appear as "¥" characters in many cases. It's not a glitch. It's the way it's always been. Yes. I always wait for the full 6 minutes until it says 100%. It's really slow, but that's the only way I can be 100%...

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

    Lunch break testing now... My first attempt at flashing "WarpSE.GW4410A.0.6d.exe" was a failure. Flashing worked fine as usual, but after that was done, I switched off power, removed the USB cable, then powered-on (what I always do), and I got the thick bar code bars. I switched off power and...

    Please be sure to test 0.5robust firmware to see if you find the same issue I did.

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

    I like the Mac-O-Meter because it's about as accurate as my EEVBlog 121GW. I show that in my video here. I recommend Mac-O-Meter a lot to people who either don't have a meter or don't want to accidental short their meter wires together at the external floppy drive connector. And the Extension...

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

    That's really why I tried to encourage my fellow WarpSE beta testers to test in the same way I did to confirm they too have the same problem when using 0.5robust firmware. I want to make sure it's not only me who has the same issue. Then we would have definitive proof. Even so, I will wait...

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

    Bad news. I still get the bars even after carefully connecting everything, and the voltages are fine. Have a look at all of the details in my video below:

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

    @Zane Kaminski I did a lot of testing tonight after work. On first power-up, I got the bars on the CRT (same as when a USB cable is attached), but I spent almost two hours testing after that, and it never came back. Maybe it was my cable insertion? Because after that first power-up showed...

    Just changed Google Drive sharing so anyone clicking the link in my previous post can access. Sorry about that.

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

    Reflashing fixed it only while on the same table that is near the PC. But that's not my workbench, so I need to move everything to do real testing. And that means disconnect the motherboard from the chassis extension harness, disconnect the speaker's extension harness, disconnect power cord to...

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

    On my lunch break now and experiencing something new. The SE won't bong or boot anymore with the WarpSE installed, despite the fact it worked fine when I ended my testing last night and put everything away. I've tried it on both motherboards. Same on both. Pressing and holding INTERRUPT...

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

    I will do that on my lunch break today. After that, I will remove WarpSE from the stock SE motherboard and test it on my SE Reloaded motherboard. Shouldn't be a difference, but I've not tested the 0.5 firmware WarpSE on that motherboard yet. What I can say is that when I flashed the 0.5...

    unknown part on 128k analog board?

    I’m no expert on 3-D printing, but from what I understand, there are some plastics that are more heat resilient than others. ABS is an all around great plastic. https://filamatrix.com/the-top-six-most-heat-resistant-3d-printing-elements/

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

    I just finished testing "WarpSE.GW4410A.0.5robust.exe": At first power-ON, it booted from my BlueSCSIv1 without problem. Great! Mouse movement seems to be normal. Great! I rebooted with my external spinner drive, and was well with that. Tetris Audio sounds really good through...

    Netatalk 4.0 - Future-proofing Apple File Sharing

    Understood. And for the record, I myself fall into your categories (2) and (3) because I have Macs ranging from 1984 to present day, and I use Time Machine for backups of my modern Macs.

    unknown part on 128k analog board?

    I do not have technical info on L2 in order to answer your question about "range." And whether or not a standard part would work is not something I have tried. In fact, I've never read about anyone trying it, probably because most people salvage L2 from a dead or otherwise junked Mac. So if...

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

    @Zane Kaminski OK. I forced fed myself in 5 minutes on my lunch break so I could dedicate time to testing the "new" ROBUST firmware Summary: BAD NEWS My 1st boot attempt with my IBM DGHS 4.5GB SCSI drive (inside HD20SC enclosure) failed with a Sad Mac... Fine! Don't like to play with...

    Netatalk 4.0 - Future-proofing Apple File Sharing

    I think a large number of vintage Mac enthusiasts are always looking at what's new in the community and examining what they may not have heard of before. Many of these people approach a new thing with this fundamental question: "What can this thing do for me?" The first sentence on your...

    unknown part on 128k analog board?

    Custom part not available from Mouser, Digikey, Console5, etc. Replacements must be extracted from gutted boards. Honestly, it would be nice if we could get a newly built replacement for those, since old parts won't last forever.
