    IIsi bus speed, overclocking/NuBus/PDS sync implications?

    Has anyone tested the IIsi in overclocked state with NuBus Adaper/card or PDS card installed? The only mention I've seen so far is this LEM blurb: Although the IIsi was marketed as a 20 MHz computer, users quickly discovered it used parts rated at 25 MHz. (Apple had intended it as a 25 MHz...

    PEx + Sun Netra t 1125 = Sun Macintosh 1125/4U

    In an alternate history, Sun bought Apple, continuing development of the iMac and Beige G3, all well underway before the second coming. The PowerExpress/9700 project was continued and further developed by Sun as the first RackMac, specifically targeted at the die hard content producing creative...

    DRAM based Mac Portable Memory Card - Newer strikes again!

    Completely missed this one. MacUser June 1990 if memory serves: @techknight If the board supports 8MB, does it stand to reason that they managed to hit the full 9MB point you managed to achieve on your card? Should have checked Newer's web site for info on this one, but no time ATM

    LCIII PowerCache Adapter - LCIII PDS Spelunking

    Interesting tangent popped up concerning a TP post about alleleration options for the LCIII: https://68kmla.org/bb/index.php?threads/wtb-accelerator-card-for-lc-iii.38988/post-421488 Passive LCIII PowerCache Adapter: There you go @Bolle what can you see?

    iomega Zip 750MB ATAPI Drive (for G4 MDD)

    A WTB request for an MDD Zip Bezel was made in the TP. Apple never offered a Zip upgrade, so iomega cooked one up for themselves. So I've documented it here. AFAIK they're scarce as hen's teeth. The only reason I have one is that a good friend here who I fear is no longer with us had...

    TEMPEST MacIntosh SE 30 1891T with optional SyQuest Cartridge Drive

    Never noticed this feature before: MacIntosh SE 30 1891T Had to borrow and enlarge this image provided to DigiBarn by the mfr. in order to read it: Neat stuff, suddenly tempted to figure out what to do with a half height 5.25" cover plate in a repro SE/30 case.

    Driving an LCD bright white from a gizmo for use as a light table?

    I've been doing nothing for quite some time, but thinking of this little project. Using a computer to drive the LCD seems a big waste of power. I've got VGA and DVI inputs and a powered USB hub for juice I think. Nifty panel with the PERFECT base for this application. I have a lot of contact...

    Link posted (in the last week or so) to Mac documentation - lost and now not found - linkage please?

     Seemed to be another treasure trove like https://tim.id.au/laptops/apple/ but appeared to me to be more DevNote related? Little help please, GREAT resource! [:)]

    Stereo Microscope = 2 Video Cameras + Raspberry Pi(S) + Phone + Google Cardboard Headset?

    I've been wanting a stereo microscope for soldering for the longest time, but no funds available for such a luxury and no place to store one. Has anyone seen such a stereoscope bodge? If not, it's time for the Raspberry Pi gang here to knit the parts together I think. Stereo photography has...

    Working a collection of 68K thru G4 Macs into a current tech 2K/1440p/QHD desktop environmet for classic OS playtime?

    The Anyone find CRTs hard to look at? thread we've got going in the lounge is great, raising a lot of good questions already. So I figured working our collections into current tech daily driver setups might make for a good technical discussion here in Peripherals. I've been watching 30"+ 2K...

    1400c Display Panel problem, has anyone seen this one before?

    Lid cover plastic's cracked in the usual places and I get different flickering patterns by flexing lid/cable. So that's where I think the problem lies. Looking for confirmation. Haven't run it in quite some time, so I'm disappointed. It ran fine when last fired up in its spot on the display...

    SuperDisk LS-120 + IBM/ACARD Peripheral SCSI Adapter in SE/30?

    New toy: IBM aCard IDE to LVD-SCSI Bridge Adapter New AEC-7722 IDE device to SCSI interface Got this peripheral (not for mass storage) adapter to hook up a laptop CD or DVD drive. Now I'm wondering at what point on the SE/30 operating system/LS-120 driver timeline might intersect? 7.5.5 on my...

    ROM Dumps: SE/30 Video ROM and TOBY DeclROM?

    n00b to this kind of thing. Is there a ROM dump utility that will work on these two ROMs or is it a pull and read on a burner proposition? I know they can be disassembled with something or other, but is there a utility for comparing the contents side by side in columns? Theory here is that the...

    Clear mouse case and LEDs?

    Question never asked came up long ago: can the LEDs in the tombstone mouse be replaced with visible spectrum LEDs and (probaby) detectors for them? Wondered about that when my Pro Mouse succummed to criminally negligent strain relief syndrome. replaced it with an LED equipped micro-mouse and...

    Laptop Optical Drive on back wall inside SE/30 case: Interference problems?

    My Pet IIfx has an internal CD in place of its 5.25" HDD for lid free NuBus Card playtime. Looking at doing same for my new, clear SE/30 testbed. IDE to SCSI keeps things more simple, but clunky with an unshielded ribbon cable. The drive has plastic windows on the bottom for interference with...

    Heatsink for a the proc on a 12" PowerBook G4/1.5Ghz in an outside the 'Book application

    Wondering if the heat spreader interface in the 12" PBG4 lends itself to a desktop heatsink standard? Doubtful, but just may be? If not I can fab a thick copper heat spreader and mount whatever I want to it? Don't think I'd need to go that far as it's a Notebook board/Proc, but how much...

    Mac Portable Peripherals - Schematic Development

    Thanks to a post by @techknight somewhere I had the connector pinout from the Schematics to begin with. Up front, started late last night. Working from the solder side of the KBD, trying to match the pinout to the connections GND seemed wonky, the MODIFIER  connections weren't making sense...

    Arduino - KBD Controller and possible Video Scaler?

    Dunno anything about these things yet, but working on that. I found a board with what should be way more than enough I/O for converting a KBD mattrix to USB. Wat's really interesting about is the Analog I/O. Is it possible to do a simple video scaler on this platform? Doubtful it can output a...
