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

    @Zane Kaminski So as to update my SE Reloaded BOM, I was searching today for your recommended 74FCT & 74AHCT parts. I cannot find 74AHCT in a DIP package, so that poses a problem for use on an SE motherboard. I was, however, able to find part number IDT74FCT257TP on DigiKey (not on Mouser)...

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

    @ppuskari Can you run the SCSI Director Pro 4.0 disk test with firmware 0.7d-fastscc flashed to WarpSE? The reason I ask is because I am getting the error shown below after all the Seek tests finish, just as the Graph tests are beginning. And boosting the Preferred size for the app in the Get...

    BlueSCSI - Open, Low Cost, DIY SCSI to SD device

    @eric I made time to test. Boots just fine after updating firmware The only one issue though, and is why I flashed the newest firmware in the first place, is that ISO images don't work. I thought they were supported on BlueSCSI v1. I have a known good ISO tested in Basilisk II on my SD...

    BlueSCSI - Open, Low Cost, DIY SCSI to SD device

    Here's how it went, Eric: Seems to have been successful, although I've not tested it yet. It flashed much faster than I expected. So fast, in fact, I thought something must have gone wrong! 😅

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

    Because my internal 800K drive in this SE is all rusted up and impossible to use, I have no ribbon cable attached. But I connected an external 800K drive and tried to share, but only my hard disk volumes appear. So it would seem that early Mac System Software did not support the LocalTalk...

    BlueSCSI - Open, Low Cost, DIY SCSI to SD device

    I've not flashed my v1.1-20220404 (USB compatible) BSv1 in ages. It has firmware VER: 1.1-20221203-USB flashed to it. I've been reading through the Github "Releases" page and also Googling all over the place, but there seems to be no detailed instructions about precisely HOW to use QMK...

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

    @Zane Kaminski Tested with SE Reloaded motherboard fitted inside the SE's metal chassis. SOMEWHAT BAD NEWS 0.7d-slowscc: Worse that my test last night. With this firmware, I cannot see either machine within the "Select a file server" side of the Chooser. (I rebooted with WarpSE disabled...

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    I know, but you know me. I love it when things are plainly stated on a grammar school level. That's really what my entire YouTube channel is about. Saying things in a more detailed yet plain way so even a true nincompoop like me can understand it! :) Being the cheapest man alive, I did...

    BlueSCSI v2 Pico - Low cost, open hardware, fast SCSI device!

    Here's a screenshot from that Github page... So just to clarify... Even though it says "BlueSCSI-Pico2-58226df.uf2" firmware can be tested "on any version of BlueSCSI hardware," the performance improvements for Write Speed only occur when you have a Pico 2 board installed, correct? In...

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

    I decided to try a Farallon PhoneNET networking test with my WarpSE Mac SE and my SE/30. Names show up in the Chooser, but I can only connect only when WarpSE is disabled, as shown in the video below. NOTE: I only tested 0.7b because I didn't have time to flash 0.7c yet. (At 5:21 I said say...

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

    Certainly. Here's the Mac-O-Meter voltage test while booted from my internal BlueSCSI v1 and with a Mouse and Keyboard attached. And you can see it draws 33.7W of power (with WarpSE installed): Note that my SE Reloaded Motherboard is still installed, and so is WarpSE running firmware 0.7b...

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

    So when you power off, press Interrupt, power on, then release Interrupt, it boots using the stock 8MHz processor and all is well with LocalTalk networking, including login?

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

    Kai, you are an incredibly kind and generous person. If you were my next door neighbor, I'd give you a call saying, "I'll be right over!" But I suspect there would be some post office gripes about the battery. The upside is that, despite the lack of Boot Camp Drivers, I was able to flash...

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

    Because I really need a way to flash at home, I spent my entire today today working on this problem. I tried using a Windows app named "brigadier" in hopes of downloading newer versions of the Boot Camp drivers, but there seems to be only one for the 2015 15" MBP 11,5, And because it's...

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

    @phipli I sincerely and humbly appreciate the cautionary words about the headphone jack output. I really do mean that. And I applaud your persistence and passionate on this topic. I also hold your opinions and work to better the vintage Mac community in very high regard. Thank you!👏 But in my...

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

    If possible, it would be great if you could test audio by installing Spectrum Holobyte Tetris and then listening to the opening music. You can disable or remove WarpSE to see how the audio sounds normally. Sometimes listening through the SE's speaker can be difficult to hear the differences...

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

    @ppuskari I have not tried any of the 0.7 versions yet. I can only say that with 0.6h, the intro music from Spectrum Holobyte Tetris sounds just as good to my ears as stock 8 MHz audio. If you have not used Tetris yet, I would strongly advise you to do so because it helps you detect bad audio...

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

    @Zane Kaminski My intention was to drive to the office (the only place where I have access to a Windows PC) in order to flash “0.7a-fastscsi”, but should I wait for your “b” firmware instead? (i’ve not driven to the office yet. I am actually on my iPhone away from home right now.)

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

    U2E & U2F chip locations use CD74ACT257E, as shown here. U11F & U12F chip locations use SN74LS245NE4 as shown here. U9D used the original HAL16L8ACN chip moved from the stock SE motherboard, as shown here. Schematic page showing the GLU chip is attached as a PDF. My complete BOM is here. If...

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

    I ended up watching videos for two hours last night. I then went back to the SE (which had been powered for those two hours), and I turned up the brightness and tested. No problems found with the mouse. I then switched it off and went to bed. This morning (after a good 8 hours of sleep), I...
