    PowerPump"ACCELERATOR" from NewerTech: is it worth cloning?

    Dunno, that's exactly what I was asking. Seems pretty cool if you have one though! Looked like a bunch of cool bits so I bought one. Almost bought another one just for the parts included. Kitting out a brand new camera for just this sort of thing! Off for three days, we'll see what I can come...

    PowerPump"ACCELERATOR" from NewerTech: is it worth cloning?

    Dunno how many Apple 601 cards are out there or how many are in these three machines. But this looks pretty handy for pushing the limits on both sides of the dual processor setup. If there aren't enough of the PowerPump out there to go around, might make for an interesting project? Other than...

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

    @saybur thanks for the invite to your fabulous project! Eyes crossed a bit while skimming the thread over wakeup cuppa joe. The absolute positioning talk much confused me. Does it really matter where the cursor is located? Looking at this from the perspective of a rotary switched KVM setup...

    Twin PCI Riser Project for TAM, 6360, 5x00 Single Slot PowerMacs.

    I think the best way to go is to do a straight up TriSlot for the topbar modded 6360. If that proves out, patched or not, the prototype run will likely suffice for the needs of lunatics like myself. 🤪 Then move on to the SetBack/Twinslot for 6360/5x00 machines we desire and possibly rearrange...

    Twin PCI Riser Project for TAM, 6360, 5x00 Single Slot PowerMacs.

    Well, there you go . . . so long as you don't develop a taste for the sweet variety in old paint. I guess the AI files will probably do the trick by themselves. I'll get a full set of .PDF versions set up to post. Doing the Tri-Slot version for prototyping should be the first step I think...

    Twin PCI Riser Project for TAM, 6360, 5x00 Single Slot PowerMacs.

    SWEET! Thanks much. :D I've got the boards laid out in AI8 for form factor and the traces as well so schematic capture should be a breeze. I need three boards, TwinSlots for 6360/5x00 and TAM. Third one's a TriSlot beauty for the 6360. Yes it'll fit nicely with topbar mod @chelseayr. ;) I can...

    Fast! CompactFlash for Macintosh PDS/NuBus

    @zigzagjoe if someone here or over there comes up with a source for the PDS connector, I've got a small box full of Blackbird bits and pieces headed your way. Bringing those internals to life and put to good use in a test rig chassis will be most entertaining, if and when. ;) Hope you don't...

    Fast! CompactFlash for Macintosh PDS/NuBus

    Excellent! Does anyone know the spec or availability of the connector needed for Blackbird PDS interface?

    Fast! CompactFlash for Macintosh PDS/NuBus

    Lucked out for a change! Looks good to me so far, dunno about connector availability. How does memory mapping line up? Luckily the Blackbirds have a pokey bridged PDS slot, later systems are 25MHz if memory serves. I'll drop this tangent now . . . couldn't help myself. :oops:

    Fast! CompactFlash for Macintosh PDS/NuBus

    Yeah, it was a crazy notion that popped into my noggin. But the only stupid question is the one that isn't asked. ;) Good point about partition capacity. Interesting, haven't looked at CF cost/capacity in a very long time. Amazon's got 4GB Transcend Cards for $21 and no-names for $17, very...

    Fast! CompactFlash for Macintosh PDS/NuBus

    Oopsie, missed that in responding to @LaPorta great goings on! Indeed, the IIfx PDS is a slot dying for expansion. How much overhead would be involved using an SD->CF adapter. If not too, too much of a hit, much higher capacity cards are available in SD, if supported? Again, fabulous work.

    Fast! CompactFlash for Macintosh PDS/NuBus

    Amazing once again! Perfect for a IIsi and SE/30 fast mass storage solution. Methinks you'd want that in a IIfx PDS variant, you know I do! :D

    Will RPi4 run OS9 in emulation

    Thanks for the tips! First step is to get it up and running at all. ;)

    Three Slot Riser for 6400 - In search of the Mythical Slot C

    Very nice, welcome to what's now a gang of three! ;) Correct, you need to rob signals from CSII go full-on PCI for Slot D. I used a cheap single slot RA riser card, removed the connector and hotwired from there to my cable monster test rig just for a screen shot op in TattleTech. Don't see...

    Power Macintosh 6500/5500 Logic Board - minimum boot requirements?

    I misunderstood, thought you meant an AIO released after the 575 was available with a Trinitron display. What a shame. If any, they really should have put a Trinitron in the gorgeous, black PowerMac 5500 Director's Edition. Now THAT would have become a collectable, even if only 15" CRT in the...

    Power Macintosh 6500/5500 Logic Board - minimum boot requirements?

    Didn't see anything like that, got linkage? BTW, take everymac with a block of salt at least 25% the size of the monster needed at LEM. ;)

    Will RPi4 run OS9 in emulation

    Thanks! That sounds like a very interesting experiment, might give it a whirl some day, but the video appears to be lost to time. I've been leaning toward 7.5.5 or even 7.1 Which puts me back down Quadra 630 and IIx/Rocket memory lanes respectively. 6.0.8 is a real temptation as that's what...

    Does the Mac II need FDHD kit for +8MB?

    Just need to use MODE32 to overcome the 8MB limit, no?

    Power Macintosh 6500/5500 Logic Board - minimum boot requirements?

    Yep, that's why I said origin was the Quadra 630 sire (introduced three days prior to LC/68030LC equipped variants) of all I like to call the A/V Slot Macs/Architectures. ;) edit: 1995 580 would be the first changeover to A/V slot/6x0 series logic board for the 5x0 series, Great Logic Board...
