    NUBUSPAS16-DB :: A daughterboard hack to restore some functionality of a standalone MediaVision PAS16

    De nada, glad it was of help. Might still want to do a bobbed version of the breakout box for the LC/PAS16 crowd?

    Radius Pivot DB-15 to DB-9 pinout?

    edit: Looked like you were drawing the headers on the IIsi version, but I guess not? Might be useful anyway.

    NUBUSPAS16-DB :: A daughterboard hack to restore some functionality of a standalone MediaVision PAS16

    Amazing stuff, love it! Might I suggest drilling three holes in a blank bracket? Had the bare NuBus card in the backwhen. Luckily Shreve Systems did a blowout sale, so I got the boxed LC version for a song and was up and running for stereo output from the DuoDock. Thanks, this reminds me that...

    'zaBox G3/266 upgrade . . .

    Wow, didn't realize the project was quite THAT old! Worked on it a bit last year, turbocharging the cooling system for using the HPV card with the G3 card: https://tinkerdifferent.com/threads/6100-g3-hpv-turbo-cooler-hack.2380/#post-20834

    Soldering new vram onto Quadra 630 motherboard?

    Aaaaaand . . . I still haven't found my Quadra 630 board. 😞 Last time I looked at this the plan was to strip the memory off the board and bodge CAS/RAS/anything else required to one of my 72pin -> multiple 72pin SIMMsaver boards as a full loadout of the hamstrung Bank on the board along...

    PerformerPro Accelerator Board by Harris International?

    Nah, but thanks! I just need to get the OEM version yours is based upon back into my grubby little paws.:D

    Best maximum partition reference table for machine/OS combos?

    Gotta set up some 128GB mSATA drives on adapters for various IDE machines with various OS installs with a look toward something like moving a drive from QS into a G3 without incident. Munged one up badly doing that quite some time ago. :oops: When I set up a big Savvio Server Drive for 7.1P...

    setting up a G4 Tower Quicksilver 933 MHz

    Read the beginning of the thread today and have a suggestion for the QS stuck Zip disk fix. My QS is on the fritz ATM, but when I get it up and running again it'll have had a 1/16" hole drilled in the Zip bezel right over the manual eject button. Dumb ( | ) design over function decision. 😈...

    Macintosh IIci Logicboard recreation

    You are one SICK individual, which is, of course why you're one of may favorites amongst the rogues galleries here and thereabouts! Rock on bro! 😁

    Fitting a IIsi Color Pivot card inside an SE/30 - How?

    I don't see why I couldn't mount my P33 vertically, connector parallel to the Pivot's passthru. There should be plenty of cubic available for it as it would be positioned far enough back from the wide section of the CRT to fit. Second bedroom/computer/bench/storage room will be set up again over...

    Fitting a IIsi Color Pivot card inside an SE/30 - How?

    I've looked int redirecting/patching the traces on the panhandle (modifying the connector too IIRC?) so as to shorten it for a good fit. I think I ran across the docs recently. Not as easily done as I'd originally thought, but doable with some logic tracing I think. Let me know if you need an...

    SuperMac PDQ, Spectrum 8, 24, Thunder ROMs

    I have a few boards, but the one I'm mainly interested in would be the very first rev of the Spectrum which is entirely programmable for any given resolution/dot clock. Just curious about spelunking VRAM for getting its contents out into the real world by bypassing RAMDAC limitations.

    SuperMac PDQ, Spectrum 8, 24, Thunder ROMs

    Again, not talking about the specific board in this discussion in terms of harvesting and displaying extended desktop. It doesn't do extended desktop does it? Was thinking it would be cool to bit-bang(?) contents of VRAM on early cards with extended desktop and shoot the entire thing out HDMI...

    SuperMac PDQ, Spectrum 8, 24, Thunder ROMs

    Yep, RAMDAC limits resolution support at the video-out connector, but not an available virtual desktop contained in Video Memory. My question to @Melkhior was about accessing that extended desktop held in VRAM that's panned through the 640x480 video connector viewport of my first rev Spectrum...

    SuperMac PDQ, Spectrum 8, 24, Thunder ROMs

    I can't get at hardly anything in my collection ATM. I've got several ROMs that need to be dumped, one unfortunately dating back several years. I never try to push any Mac much beyond its release OS. Really only run early 7, the 7.5.5(?) general release and OS9 RAMDAC capability seems to be the...

    Project30 - IIsi NuBus Adapter in SE/30 - fifth edition

    OK, I was remembering when @Melkhior had said that NuChip30 was developed for 68030 systems up thread. Turned out not to have been the case, looks like NuChip30 along with MDU for the IIci and for use in the IIfx. NuChip30 supported 20/25/40MHz 68030 systems, after that they went to NuChip33 I...

    Project30 - IIsi NuBus Adapter in SE/30 - fifth edition

    Another way to look at this? NuChip was developed for the revised Macintosh II, replacing the discrete logic NuBus controller in first release Macintosh II. As such, its origin was the 68020 architecture. It was adapted/kluged into the stopgap 68030 II/IIcx architecture. NuChip30 was likely in...

    Project30 - IIsi NuBus Adapter in SE/30 - fifth edition

    Great , , , just maybe. Let me guess, LO0 would be the clock eliminated as a NuChip30 input? Thanks again for your help. LO0 would seem be generated in UG11 and UF11 it would seem? I guess it would be my next step to doink in all inputs and outputs from that mess to see if their innards...
