Very interesting, reminiscent of Virtual Desktop features of early VidCards supporting far higher resolutions than their RAMDAC and contemporary displays could support. What's the highest resolution that card can support on its external connector?

. . . yet again as once more, this is way above my pay grade. :oops: When spec required 5V for LCD and 12V for Pi/CM4 board, notion was to use a PicoPSU and its AC adapter. Figured I only needed current limiting resistors for those two Pico lines. Now I only need 12V input for both, which...

@Drake developed the perfect interface for the PowerBook 100 Trackball: https://tinkerdifferent.com/resources/adb-usb-keyboard-mouse-adapter-firmware.26/ @RolandJuno over at the MLA picked up where I left off on development of the Portable's peripherals...

Thanks guys! 🙂 PicoPSU discussion here: https://68kmla.org/bb/index.php?threads/picopsu-is-waste-heat-proportional-to-current-used.49529/post-557442 Still need to locate the 1400c KBD adapted base, just love that heavy use patina of BabyPB contrasted with the 1400c KBD. Found the lid with...

PowerBook 100/2300c LCD/Logic board upgrade has been in process for well over a decade. This revision has been on the back burner since the Compute Module 4 first came out. The I/O board makes it perfect for this upgrade of my beloved BabyPB, very first laptop, bought new and maxed out in the...

I did a nice workup years back at the MLA, but I think actual content was lost in the great pixel robbery. https://68kmla.org/bb/index.php?threads/powercd-base-unit-teardown-pics.18975/ Lots of people tried hooking a SCSI cable up to the most definitely non-SCSI DB-25 interface of the flying...

I realize drivers would be the issue, just curious about backward compatibility of 040 PDS? That's assuming the Rocket's Daughtercard Interface is as simple as that?

That's good to hear. If I get one of your enhanced clones I won't have to jigger a loopback cable for the internal drive of the IIsi/Rocket. Still curious if it might be coaxed into talking down to the 030 PDS?

Interesting, could be they're only advertising that 5MB/s maximum spec to avoid problems? Fast/Narrow SCSI II spec. is 5MB/s to 10MB/s, but most drives weren't capable of such transfer rates in the days of Rocket. That's the standard Fast/Narrow SCSI II Connector, Fast/Wide SCSI II same but...

Go for the original 128K prototype feets, complete with Apple Logo. ;)

. . . to raze the malignant dining room table monster. Can now concentrate more clearly on the real world hardware phase of a long running obsession. :p

That thing fell outta' the ugly tree hitting every branch on the way down and landing on its head. Given that, the resulting dented, rumpled bedspread lookin' translucent top might be employed to apply lipstick to that freakin' pig. Installation of a Pi controlled LED light show underneath might...

Very, very nice. Don't forget my licensing fee for getting you onto this track way back in the thread! :ROFLMAO:

Update on results of research phase: Just for shiggles and gits . . . . . . couldn't resist bodging ComSlot->full PCI conversion on cable based single slot riser Test Rig for A/B/C. Didn't test this lashup for full function. Borked something on the test riser at some point...

. . . and the mythical no more: Slot C for Alchemy! Cleaned up baseline research, reference condensed from posts in multiple threads on three different forums over the past 5 or 6 years. Thanks to all who've helped out in the seemingly interminable research phase. At long last development...

That's exciting enough from where I sit! Thanks for any efforts you can put forth, we're only running +5 years on the project to date. ;)

I love it, but the front bezel is the only Lisa component in the collection. But a version of that bezel with a single TwiggySlot replacing the Sony slot would have me hard pressed to resist it. Such optical drive compatibility for clear SE/30 coupled with printed Twiggy enclosure would be...

Getting there! Pulled the copystand down from its bat perch on the shoji screened living room HackStation shelf wall yesterday. Just ordered up an iffy macro lens for it. Not too worried about glass condition for my use case, got it mostly for the AI-Converter Ring. I can troll the...
