    Early Macintosh home brew 4MB memory upgrade board development

    It isn't successful, as unfortunately it still doesn't work, but that's off-topic For the three different upgrades I have had my hands on, yes they all do use Mac Plus ROMs. The difference were on how they patched the ROM to make the SCSI contraption to work. They are not checking the RAM size...

    G5 quad showing leaking caps

    heh, that's tough. For note, all of my three single 1.8 died last year or a couple of years before and theses caps were dead as well. They are from the Pentium 4 capacitor plague, so are likely to have more capacitor issues than earlier machines

    PowerBook 540c black coffee edition

    Can confirm this one works fine as well. There is a 18MHz-ish EOL Epson around as well, which will make your CPU go to 36 MHz if 40 MHz isn't stable

    TashRecorder: a Farallon MacRecorder compatible clone

    Intresting, SoundEdit 1 crashed on my Quadra as well. I think there is some line in the ReadMe file addressing that.

    TashRecorder: a Farallon MacRecorder compatible clone

    Nice, well done ! What model of Mac are you using it with ? Maybe @Mu0n has a board left Nah sorry I'm only doing TashPad for now. Every board from the prototype run has already been claimed I wil agree that it's difficult to sell. I'm eating the cost and selling at a loss most of the time...

    Hootswitch, a (work-in-progress) Apple Desktop Bus switch

    FreeRTOS is nice if you want to add features such as Wifi. The downside is that your peripheral needs to be top notch with the timings, you can't really do active loops like with bare bone coding, mostly because you can be scheduled at any time I'm assuming the PIOs can do that just fine ?

    Hootswitch, a (work-in-progress) Apple Desktop Bus switch

    Niiice. Is this barebones or are you running some kind of RTOS ? Also I see your wife has made another great art. Is the buzzer hooting ? Edit : you also need to put a quadrature in port so I can daisy chain my stuff :P

    Macintosh SE crushed

    Just out of curiosity, what kind of BlueSCSI did you use (a picture of it would be fine) ? Why do you suspect it ?

    FloppyEMU IDC20 Connector Pin Out Help

    Yes. The TashTwenty IDC<->DB19 adapter (so no IDC PIN9) is working just fine with Floppy Emu on a Macintosh

    FloppyEMU IDC20 Connector Pin Out Help

    Not sure if I understand correctly, but you may want to use the standard pinout for the DB19 cable. Here is the pinout for an IDC20 to DB19 from BMOW (https://www.bigmessowires.com/2015/04/09/more-fun-with-apple-iigs-disks/) Ignore the logic things On TashTwenty, we didn't connect the -12...

    The most horrible USB card layout I’ve ever seen

    Plot twist: the traces ARE the overcurrent protection :LOL:

    TashPad: Super Nintendo to Gravis GamePad ADB Converter

    @Daniël got the 2.4G SN30 working with TashPad https://www.8bitdo.com/sn30-wireless-for-original-snes-sfc/ Same as with the Bluetooth version, no visible lag.

    BlueSCSI HDD Speed ...

    Can you try to swap the SD cards around ? During early TashTwenty testing we noticed that some cards had really bad write latency, which could result in bad write performance in some cases

    BlueSCSI HDD Speed ...

    Can we assume that you are using the same SD Card with both devices ?

    Quack: Bluetooth & ADB Mouse "Dongle" for the Macintosh 128/512/Plus

    Small updates: - there is finally a front plate i'm happy with. It has been shipped to previous owners as well. - now the right bluetooth click acts as an half click, like some devices did back then

    Yeah that's fair, the 140/170 indeed looks like to be very odd. It's also the same ROM as Quadra...

    Yeah that's fair, the 140/170 indeed looks like to be very odd. It's also the same ROM as Quadra 900s, who know how long that board has been in development …
