    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.

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

    Date references are easy to forget and confuse, so I shall rename it: WarpSE.GW4410A.1.0robust_OLD.exe When and if I mention it in the future in this thread, I will call it "ROBUST OLD". That will make it 100% clear. I've not had opportunity to test your new ROBUST firmware yet. I will do so...

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

    @Zane Kaminski I just flashed the firmware attached to your "Oops!!" post. I'm sorry to report it's bad news. (I have 4MB of RAM installed, by the way.) I had no issues booting prior to flashing this firmware. (I had been testing ROBUST without any booting issues before.) But my first...

    Netatalk 4.0 - Future-proofing Apple File Sharing

    I only noticed this thread today. I'm big on "layman's terms" and dummying down difficult concepts into a form digestible by mortal man. You know... FOR THE REST OF US. I Googled a bit to figure out even what Netatalk is, but that led me to a bunch of techno jargon that made my eyes glaze...

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

    My mention of SE ROMs in my earlier posts was done merely to say that if you have newer ROMs that support the 1.44MB drives (e.g., an SE FDHD), then you cannot boot into Macintosh System Software versions older than System 6 because the new ROMs require System 6.0.3 or higher. I have the older...

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

    In light of the past reports by @techknight about GCR disk incompatibilities with the first WarpSE firmware (which seem to have been fixed in the "ROBUST" firmware I am tested with now), I decided to do further GCR compatibility testing today, just to be 100% sure. I connected my Macintosh 400K...

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

    And just to clarify for others reading this. The Radius Accelerator 16 and 25 cards use a 68020 CPU and 68881 FPU. WarpSE uses a 25MHz 68000, but no FPU. Hence the impressive performance. @JTRetro what is the minimum System Software required for your Radius accelerator? As mentioned in my...
