    Anyone have a MacCharlie keyboard unit?

    Not the only one, but could be one of only two? I've got both the platinum ADB and beigy phone plug versions of the datadesk MAC-101. Really curious to see an in depth look at the MacCharlie board. It was a surround for Apple's KBD...

    Quadra 950 Chassis

    Check out the great work @360alaska did over in the MLA thread: https://68kmla.org/bb/index.php?threads/3d-printed-objects.4483/post-335383 @360alaska how about extrapolating a full 950 front bezel to fit an ATX case of some sort/size as I've described?

    Comm Slot II 10/100 Ethernet Cards

    Very nice! Almost two(?) decades ago I played with going the other way, a CSII Slot edge card to PCI Slot Riser test setup. Wanted to see if any PCI cards might be hoodwinked into running off CSII. Got one of those on the way as well? :D

    Comm Slot II 10/100 Ethernet Cards

    Cool, cannot imagine it wouldn't be simple enough to implement "slots" above and below the traces along with slight notches at top and bottom. Using a hacksaw would make for a clean, straight cut. I "hacked" many a prototype board some thirty-five years ago (half a lifetime! :oops: ) along...

    Comm Slot II 10/100 Ethernet Cards

    Wondering if my snappable board suggestion might have merit?

    Quadra 950 Chassis

    ISTR a printable model for the CD bezel of the 950 is available. Extrapolating from that should give you a great start. You need only elongate the model at top and bottom implementing the returns for those panels and adding detail. The FDD "stripe" should be simple. Such would simplify your...

    Comm Slot II 10/100 Ethernet Cards

    Looks like cable connection? Keyed PCB connector?

    Comm Slot II 10/100 Ethernet Cards

    Now thinking that using the split off connector section would be optional. A proper panel mount connector could be hooked up the the same headers on the shortened main board?

    Comm Slot II 10/100 Ethernet Cards

    Aha! Glad to hear that. Didn't know about magnetic components, such would explain the ginormous, boxy form factor of the panel mount connectors I've seen. Saw one terminating in a header connector somewhere. That'd be handy. Wondering if making provision for snapping your PCB into two parts to...

    Comm Slot II 10/100 Ethernet Cards

    Nice, thought it had to be a lot more than that, but i guess the chip was intended to be routed simply to the PCIe edgecard. ??? Now I'm confused. Wasn't clear at all in my post, I do them in the AM over coffee most of the time.:oops: Thinking further about using your card in the TAM, it might...

    TAM - Internal PicoPSU - AUX Power for Expansion Slots

    Lots of activity on the PSU front for 6500 recently and in the far distant past. Some 14 years ago I was looking into 6500 and Beige G3 ATX conversions. Going for an ersatz TAM/FatBack form factor build now that will be powered entirely by the 250w PicoPSU pictured above. In his discontinued...

    Comm Slot II 10/100 Ethernet Cards

    Indeed! Love your work. Thinking you could cram your design into a lower version of TAM/CSII riser's form factor? Looks simple enough in terms of parts count. Pigtailing the board to a panel mount connector for the backplane opening allows all kinds of tomfoolery! 😀 Not to mention opening your...

    TwiSlot PCI Riser and ComSlot2 NIC repro in widened CS riser form factor

    Top View of same, 6360 is great, can still use the CSII NIC along with the additional PCI TwinSlot gambit. A USB WiFi Thimamajig attached to a powered hub, fed from the pigtail should be something like 10% better throughput than the CSII 10bT card, no? TAM Tent Template shows the CSII...

    TwiSlot PCI Riser and ComSlot2 NIC repro in widened CS riser form factor

    Trying to keep things as simple as possible, I sourced a six inch right angle FW M->F pigtail cable to match to the 12 inch RA USB M-F pigtail cable on hand. Looking at my original TwinSlot Riser setup, I'd figured a setback increase was in order. Experimentation proved that an additional .3"...

    Schematics for PowerBook Duo model

    Hearing mention of vestigial implementation on the 230 board for the second serial port just now blew me away! How much higher throughput might that Printer Port(?) connection have than the Modem card interface? Thinking it might put an entirely new spin what I recall as a Modem WiFi card...

    OMG!!!!! @This Does Not Compute enough with the tease! Is it the tablet or do you have a specific Duo schematic? 😀

    Portable keyboard Matrix?

    Glad you guys like it! Did you get a load of my matrix test bodge? 🤪 Hoping somebody will wed that table/switch matrix to a USB KBD controller at long last. PiPortable hybrid is an obsession awaiting retirement, which will be a year or two off.
