    IIsiColorPivotII_PDS_Card_HackProject™

    Wow, this thread is getting waaaay cool! 8-) I know, I still owe several replies (and research) here... :I but for the time being I see very interesting the idea of a grayscale SE/30. With the video card issue already solved, this is what I think about the remaining tasks: The grayscale...

    How to add a CD-rom drive to a Macintosh Classic?

    I'll be far from my Macs for a few days (and pretty busy!) thus I can't confirm this for sure, but I believe that even a stock SE/30 should be able to boot from CD-ROM provided that: The CD is bootable The System version is compatible with the SE/30 (up to 7.5.5) That system's configuration...

    IIsiColorPivotII_PDS_Card_HackProject™

    Hi and thanks (again) for the warm welcome... Things aren't that complicated, just more/new tasks at work with less pay :-/ but still can afford some hobbies anyway. Back to our thread, I've been experimenting a bit with the IIsi and the Radius Pivot PDS card... first of all, after this...

    IIsiColorPivotII_PDS_Card_HackProject™

    Phew! Hi again! Sorry for being absent all this time... life's got rather complicated and, among other things, I've been giving birth to my very-own-designed 6502 computer -- now that's retro! ;) Fortunately, things are starting to settle down now, so I'll be back into the delicious world of...

    50% faster graphics Mac IIsi, Overclocking?

    I overclocked my Quadra 700 with a socketed 64 MHz oscillator: The hard part was desoldering the ground pin... but otherwise it's a fairly easy procedure. I tried slower oscillators also, for the fun of it: down to 40 MHz is OK; 32 MHz starts having video issues... 24.576 MHz or lower, no...

    Booting 7.0.1 From:ROM (Mac IIsi) /W Apps! My New Toaster:-)

    AMAZING! We already knew it was possible, but seeing it actually running is just great 8-) If I understand it correctly, if no key is pressed upon power-up, the machine will try to boot from an ordinary disk, right? Could that be modified in order to make the Copy ROM to RAMdisk boot option...

    CC and C

    Now that you mentioned the roadmap for CC upgrades... the 68LC040-based LC575 board is an easy upgrade, but why the change to a full 68040 is marked on red? Is it really "dangerous"? I expect it to increase heat dissipation, but fitting a small heatsink should suffice, am I wrong?

    Removing startup artifacts of "improved" ROM SE/30!!!

    OK, let's go! (I'm writing this on the SE/30, after checking what you said) So does mine... These are exactly the values I read at $50F14806 if I change the volume setting via the usual control panel... Well, here we are a difeference: mine reads $02. FWIW, at $50F14801 is $01. Done ;-) I...

    IIsiColorPivotII_PDS_Card_HackProject™

    Phew... After a long time with tons of work, I'm back again ;) Glead to hear the discussion going on. I've had little time to keep twinkering on it, but here's an update/remainder of the state of my research: •The card supplies a 640x870 (portrait) signal, no matter the sense code applied...

    Removing startup artifacts of "improved" ROM SE/30!!!

    [Wow! It's been a long time since my last post... I've been crazy at work these weeks :( I hope to catch up soon!] @onlyonemac: If memory serves, I tried every possible value for the register, including each combination of D0, D1 and D3 -- the volume did turn down making the sound...

    Fabbing 30 pin SIMMs

    2 & 8 MB SIMMs do not work on the SE/30 -- just 256K, 1, 4 & 16 M :( The IIsi (and I presume the IIci too) seems to take almost anything 30 pin, parity or not, composite or not, including 2 and 8 MB sizes. But the clearance issues aren't unique to the SE/30: the Quadra 700, for...

    Another IIci ROM hack

    Oh dear... the MacMini is running 10.5.8 -- the system confuses the eight next to the ending ')' for a smiley xx(

    Another IIci ROM hack

    Just downloaded, works great on: iMac 21.5" Core-i5, 8 GiB (OS X.7.5) MacMini Core2Duo, 2 GiB (OS X.5. 8) If needed, I can setup the last machine with the originally supplied version of Tiger, for further testing. Thanks again! PS: Any remarkable improvements in mind for the next batch of...

    68k Soft/Hard Power and ATX conversions . . .

    Strange... Please double-check all connections. You did remove the jumper previously used for firing up the PSU, right? Click here for the IIci's PSU pinout -- it's the same as the IIvx, Q800 etc. Also, make sure that the metallic enclosure of the transistor isn't touching any other contact --...

    68k Soft/Hard Power and ATX conversions . . .

    If I understand your idea correctly, that Universal PSU-Adapter PCB shouldn't be difficult at all... just take my previous schematic (for the IIsi) and connect the lines in parallel for each Mac-side connector. Some lines from the ATX PSU (e.g. the +3.3V rail, unused and thus not shown in the...
