    iomega Zip 750MB ATAPI Drive (for G4 MDD)

    I'd imagine it's identical to the OEM unit. Only change would be to the leave the bottom section solid as opposed to articulated. It's be so much easier to have the opening laser cut out of your OEM bezel . You'd need to remove the cam from the read of the door in order to snug the drive up...

    Good & reasonable HDMI scaler: Extron RGB-HDMI 300(A)

    I've been looking into this one for Radius cards recently. https://texelec.com/product/rgbtohdmi-ttl/ Could be simplified tremendously given single bit images on the Compacts? Getting rotation set up for the Portrait Cards is at the top of my list. I think @max1zzz is using the original, analog...

    Mac Plus/SE Performer accelerator build

    Performer/SE build has no need for direct connection to the 68000, the PDS slot itself is a direct connection to the CPU. SE PDS includes the C16M reference clock that became a standard feature of later PDS implementations. That would be why the clock doubling GAL at U7 is not required for the...

    Listing of ReMix Logic Board Projects?

    Thanks much for all the input, gang, very helpful. One more in the works: @max1zzz is reshaping ITXPlus. Obligatory Tangent Time: One day I'll get around to building the SE/30 Remix with my dead board, but not a purist about these things whatsoever. I'm a huge fan of @max1zzz reshaping of...

    Jasmine Technologies BackPac 40

    Someone has just gotta model this thing for printing! Adding it onto the back and using a PCB adapter offsetting its neck board gubbins down and to the left is the only possible way to fit my 10" Color CRT "into" an "unmodified" Classic Mac case . . . sort of. 😜

    Mac SE Radius Full Page Display 64KHz

    Excellent, just starting to work on that setup! Should have that board here in a couple of days, but no cable. Can you buzz the connections from 9pin header on the PCB to the DE-9F positions on the backplane plate for me? Looks like there are only three wires implemented? If so I think that'd...

    Radius FPD w/9 pin header on board or DE-9 connector on backplane: relevant links to info from anywhere wanted for scaling project

    Any links to any info at all on these cards/displays would be appreciated Eventually looking to clone FPD and TPD cards eventually, but looking at nailing down output/scaling solutions first. Had some luck with TPD/Extron Scaler in the past...

    ITXPlus: A ITX Sized Macintosh Plus Logicboard Reproduction

    @max1zzz what's all that cable crud at top right of case? Obligatory Tangent: That setup you have would make a great riff on the OUTBOUND 125 for mains power limited Portable Mac playtime. VGA LDC Controller/Panel combo keeps it thin. Front bezel overlaps letterboxing bars. Move KBD to...

    ITXPlus: A ITX Sized Macintosh Plus Logicboard Reproduction

    I don't even see room for a power supply? Would it be at the front of the case or is PicoPSU implementation specified by the mfr?

    Mac Plus 68020 Accelerator

    In house Mac Plus upgrade card for 68020 coding makes a world of sense. I'd like to see how that PSU contraption looks installed on the an open Plus chassis. Why button them up at all? Might that oddly placed fan have been pointing at the hottest parts of the Plus A/B? If David Ramsey...

    ITXPlus: A ITX Sized Macintosh Plus Logicboard Reproduction

    Is that an ITX case? I don't see provision for an expansion card or is that a perforated backplane cover plate?

    Mac Plus 68020 Accelerator

    That makes a lot of sense in the context of my Folklore read, But why 12MHz parts, if indeed they were such as seemingly marked? Was an 8MHz 68020/FPU combo ever even released? That's what I was wondering about, makes a lot of sense. I tke it thad downshifting from 16MHz to 8MHz is more easily...

    Mac Plus 68020 Accelerator

    Yep on 16MHz clock halving done on the Compacts* ** logic boards to generate the 8MHz CPUCLK. But nope, that'd require a bodge to tap the 16MHz clock line at source somewhere on the Plus logic board on installation. That would radically violate the KISS principle. ;) Plus predated C16M on the...

    Mac Plus 68020 Accelerator

    That doesn't stop the Performer from running at 16MHz sans crystal. The difference between Classic and SE versions of Performer are the GAL at U7 next to the SE PDS slot with what became the standardized 16MHz reference clock in its pinout. Assuming the clock doubling formulas (phase lock...

    Mac Plus 68020 Accelerator

    Unless 12MHz is a magic number for running Logic Board->Analog Board->CRT Neck, I really can't see any point in Apple looking at something like this? Prototype s boards seem to have been marked as such, but this one may have been special enough that no mistake could have been made. That custom...

    Mac Plus 68020 Accelerator

    If CPU and FPU (marked 12MHz?) are really only running at 12MHz it's no wonder nobody has seen this thing. It would then only be half the performance kick of the 16MHz Performer that we've already cloned. When was the 16MHz 68020 released? Radius16 was one of the first Accelerators for the Mac...

    suggestions to pack & ship a (black) 5500

    Cool, I'd consider myself lucky. Did you remove the lower bezel bits for the trip? I would have. ;)

    suggestions to pack & ship a (black) 5500

    I wouldn't wanna bet on a long car trip with the CRT face down strapped into the back seat. Don't is the best answer I've read.
