    PowerBook fun and games begin with Raspberry Pi CM4Lite and its I/O board!

    Main thrust of this will be my beloved first laptop, bought new on clearance PowerBook 100/maxed out memory card and faster modem card from APS. Stuffing it with CM4 goodies resumes ancient project after first take now abandoned. Have to find one more box with the base unit inside. But stretch...

    Need solution for HDI-45 to DB-15 connectors for video out

    DA-15??? I thought you were doing VGA conversion for HD15 on board? You definitely don't want to see anyone hanging a VGA converter off that thing!

    Need solution for HDI-45 to DB-15 connectors for video out

    Very nice! If you leave the shroud/pins at that height it would probably clear the (5mm+- tall) cooling vent louvers of the 7100? Didn't realize you had in house printing capability. Color me jealous. ;)

    Very cool! Trimming pins on the insertion side would be a no-no. I've clamped the pins in a vise and tamped the plastic spacers down to length. Given the thickness of the printed case, trimming them on the solder side shouldn't be necessary. Again, fantastic work! ;) edit: thinking about it...

    Radius Rocket & SCSI Booster Clones

    Indeed! Said that in the first response to his announcement over in the MLA Trading Post thread. Amen to that, I've go the SCSI2 Daughtercard on hand.

    Radius Rocket & SCSI Booster Clones

    If that's the case and we have the formulas for the GALs, might someone accomplish that funneling of GAL logic intto modern gate arrays? Thinking here would be that the logic upgrade would be more power efficient and capable of running at the full 40Mh Stage II clock while still supporting...

    Need solution for HDI-45 to DB-15 connectors for video out

    Didn't take it that way at all, not saying my way is the only approach either. ;) My (unvoiced?) concern has been re-alignment of the adapter PCB when re-installed after having been removed for pulling the logic board. The support pin/stud spread at the four corners help to ensure alignment and...

    2025 PowerPC Challenge

    Not a big deal for me, been using PPC for my Graphics work in OS9 all along since its intro. Never switched to OSX because I've got tens of thousands of dollars worth of Graphics and CAD/CAM software/hardware, much of which never made the jump to X before I closed up shop in 2004. Very nice to...

    Apple Lisa Mouse A9M0050 - Replacement Shell

    I'd love to see hybridization extended to single Twiggy slot/Profile Drive vents for BluRay access. So far as printing goes, I like the notion of printing it in sections. Once joined, print assembly would be sanded smooth and painted for Prototype correct finish. Plans for my bezel include...

    Like I said, that version was measured mostly with Mk.1 eyeball. Here's the updated version ready for printout testing. Clearances should be appropriate. I'll whip up a 3D model to test clearance for the PDS bracket knob. My main concern with your vertical card would be lack of sufficient...

    Too tired to take a better pic tonight, but this'll do for now: Time to buckle down and take off some real measurements for the next version, here's the .pdf for printout as it stands:

    Apple Lisa Mouse A9M0050 - Replacement Shell

    Apparently they've borrowed Lisa bezels and have done a hybrid version: https://maceffects.com/products/apple-lisa-1-2-hybrid-bezel-beige-clear I've already got a front bezel (and that's the extent of my Lisa gear) and wish I had a Twiggy Drive Bezel.

    Apple Lisa Mouse A9M0050 - Replacement Shell

    Never mind the guts of the thing! Who's gonna do a wireless board/dongle? Standard dongle with adapters for Lisa et al (ADB) connectors would be the cake inside the icing! :) Using one of my very inexpensive, matched wireless KBD/Mouse sets seems perfect. 1) design a chassis/cover for the...

    Need solution for HDI-45 to DB-15 connectors for video out

    Thanks for agreeing to technical, if not common use terms. This is, after all, at least a half assed engineering endeavor. :ROFLMAO: Initial insertion has to be spot-on as that's when the D/F tape of the case is set. PCB will need to be held tightly, keyed exactly in place sandwiched between...

    Need solution for HDI-45 to DB-15 connectors for video out

    I'll see what I can do after work tonight. We're talking about three connectors, HDI45, HD-15 and DA-15, DB only refers to the form factor of the BB-25 shell. HD-15 is three rows of pins the the 9-pin DE-9 shell. Pickin' nits here, but technically correct terminology helps much when working as a...

    Massive (filthy) find in South Carolina

    Thanks! Got a value I should use? Soldering them on should make the jumble more interesting for the final countdown. Will randomly cris-crossed leads be helpful for the final countdown? Edit: just looked at the pic I posted. I think I'll make an nice stand to hold the bottle horizontally...

    Need solution for HDI-45 to DB-15 connectors for video out

    Just re-read my post, seems kinda blunt, no criticism intended. I've got both cases handy, but haven't printed it out for fitment. I'll post a .pdf you can print out for reference, including an outline of the space available for both cases. Offset should be plenty for PDS. May be a bit too much...

    Need solution for HDI-45 to DB-15 connectors for video out

    Great stuff, but why do you have such a large horizontal offset between connectors? Such a wide spread works well enough on the 6100, but not at all on the 7100, where the cooling vents preclude such an arrangement? The slight offset to the left in my proposed layout clears the PDS expansion...
