    "portable"/"slim" 6200/5200

    @noglin i would expect that your video out issues are due to the fact that these machines need the monitor ID pins set so they display the correct resolution/frequency. S19, S20, S20, S21 need to get wired up correctly to get the right signal. if you ground Sense 0 (Monitor ID 0, S20)to Ground...

    Performa 475 and MacOS ...

    no worries, It’s a later version of the SSCI/link driver that I made a standalone installer for. I wasn’t sure if it would work on non English system installs. I’m not sure why you had issues with large ftp transfers though. Regardless performance with a LC PDS card is going to much better...

    sd based scsi zip/jaz drive

    @mogs i dont think it would be to crazy firmware wise.. ive been pretty busy with life lately so i havent had much free time and to be fair im much better with hardware the writting C code. however i think the ZuluSCSI code already has alot of whats needed already there. the main thing at least...

    A friendly reminder that MacTCP performance is godawful - OpenTransport is nearly 3x faster

    not sure if ive messed up my testing but for me on SE/30 running vanilla 7.5.5 i get 160KB/s with MacTCP v2.1 with Open Transport (v1.1 according to get Info) i get 64KB/s after installing OT v1.3.1 i get 64KB/s worth pointing out that i use SpeedCopy extension so i haven no idea if that skews...

    sd based scsi zip/jaz drive

    from what i read it does allow hotplugging of a sd card. however in the case of a mac that would still require a bus rescan and will still pick the scsi id of whatever hdd images are on the sd card. whats needed is for the firmware itself to report to the host (a mac in this case) as a fixed...

    Struggling to remove SE/30 axial capacitors old leads - any tips?

    what works for me: if the caps had leaked at all i find that using a fiber brush pen on the solder joints before i apply fresh solder helps alot then i add fresh/extra solder before i either use some desolder brainf or my desolder gun sometimes for through hole parts it helps to used s hot...

    sd based scsi zip/jaz drive

    its something thats crossed my mind a lot over the last couple years (ive probably even mentioned it at times here too). to make a modern zip or jaz style sd scsi drive solution. basically a sd card scsi solution that has a fixed scsi id or better yet a set of jumpers like old scsi drives did to...

    Netatalk 4.0 - Future-proofing Apple File Sharing

    thanks, i was able to get afppasswd working now. in fact the instructions you just gave make much more sense then the manual page ive used netatalk on an off over the years since either v2.0 or 2.1 and i definitely agree that the config files used to be full of bloat. i used to just delete them...

    Netatalk 4.0 - Future-proofing Apple File Sharing

    just upgraded from netatalk v2.4 to v4.0.3 with no issues on Fedora 40. for curiosity sake i tried to setup uams_randnum.so to see if i could get that running but afppasswd doesnt seem to work. it just says the following when typing in terminal: afppasswd: /usr/local/etc/afppasswd doesn't...

    Mac SE/30 only sees 1024kb of ram regardless of the ram attached on either bank?

    You can boot the se/30 without ub11, it’s been awhile since Ive done that myself but I believe you might need to manually trigger reset. Pin 5 of ub11 is the reset signal, it’s active low so grounding it momentarily should work tl071 is an OP-amp used to boost the line level audio signal for...

    se/30 dual slot PDS Gerbers

    It’s likely what @cheesestraws mentions above about having the same slot ID’s. Some pds cards have pin headers to select slot ID and some have presoldered jumpers thst would need removing/swapping Being the a single card connected to either slot runs fine I’m sure you’ve assembled you card...

    Mac IIci Battery Bomb workaround - continuity points for new battery holder?

    D7 and D8 are actually diodes not transistors. i believe they are SOT23 packages, and just a generic signal diode like a 1N4148 or 1N914. They are just used to stop voltage back feeding with the battery circuit so any diode similar to what i just mentioned should also work too. if you cant...

    Mac IIci Battery Bomb workaround - continuity points for new battery holder?

    using your picture above as a reference the positive battery terminal connects to the top right pin on D8, and the battery ground can be connected anywhere that's convenient such as the top right pin of D7 or the right side of the C20 capacitor

    "portable"/"slim" 6200/5200

    I don’t think I have any pictures of that psu mod I did at hand but basically it’s the same as any atx to Mac style conversion you just wire up the +5, +12 and ground to the appropriate pins on the logic board slot harness thing and don’t connect the third ground/3.3v connection at all then on...

    SCSI to Ethernet Adapter on New Hardware

    That looks really good. Just wondering are the led’s just shinning through the fr4 with no solder mask?

    "portable"/"slim" 6200/5200

    The different Color’s was just because I had a few kg of different colored filaments and I used whatever I had hooked up to my printer at the time I printed different parts And yes be careful at the 3.3v pin on the psu. I actually disconnected that ground wire and installed a small 3.3v...

    "portable"/"slim" 6200/5200

    ive done exactly this a few years ago. A 3d printed case for a 5400 logic board that slots in the back with a built in floppyemu, and using a Pico psu. It was just something I messed around with when I got my first 3d printer and was learning to use fusion360. the goal was to eventually refine...

    Mac mini compatible optical drives?

    it was about two years ago when i replaced my mac mini drivewith the UJ-875 but i dont recall having any issues with native finder burning. usually as a matter of habit if i replace a mac cd/dvd drive I test that out along with iDVD support (or is it DVD player?? i forget). While i generally...
