🤣 The OEM brick is a great example, thanks! PicoPSU 12V input jack replaces the Duo's power input jack, no brick inside. Only the PicoPSU is enclosed within the Duo case. Don't have power requirements of all components or the peripherals in hand as yet. Duo is worst case scenario and a handy...

I've got a high output model/power brick on hand and a 160W PicoPSU on the way. Using the 160W unit inside a Duo case to power: RPi Compute Module 4 RPi Pico KBD Matrix to USB Converter Duo TrackBall (ADB) ATmega32u4 based TrackBall to USB Converter 10.1" 1920x1200 LCD/Controller Assumption...

Fabulous! 👍

Knowing < jack, I'm curious about your image. Is it set up with Mac emulation as shown? If so, what System is up and running out of the box? Installing I/O Board/Compute Module 4 in a dead Duo 280, not so worried about networking. If not, are there any images with Mac emulation/Linux ready to...

A remix board for NuBus PPC Macs with built in VGA out replacing that &($*&(%&%*& HD45 port might be interesting?

What was the transfer rate of SCSI Slow/Narrow on Sun workstations, others? SCSI on the Mac was an abomination. Indeed, it also sits on the Rocket's 33MHz PDS. Fast/Narrow SCSI isn't 5MB/s, the spec is 10MB/s for the Rocket's SCSI II Daughtercard, no? Got a link to that LEM Gem? They got...

The gears in the latch mechanism sometimes get chewed up. Take a look at that.

Fabulous work, can't believe I missed it! Thanks for reviving the project as it opens up some very interesting possibilities. Off label use of Rocket supplement: Haven't played with my IIsi/Rocket hack in quite some time as it only works under RocketShare. Wondering if ROM modification might...

OK, it's Friday night in my world, so whilst partaking in adult beverages, I've pieced together the clearest diagram I can manage at this point: All connections from edge card to Slot_A are 1:1. Reserved pins of PCI spec hijacked for nefarious purposes by Apple for additional slots are...

Aha! Thanks for that reality check. Hadn't noticed that. 😳 The only DOM drives I've bought so far are untried, but because the do not have that "standard" DOM interface. I need to build adapter PCBs to use them flipped over atop the Tempo-trio card setup in the top position of the proposed...

I've been looking into 44 pin Disk On Module for 1400 etc. Has anyone gone in that direction? 44 pin DOM

Spotted what might be confusing in the ancient Buzz-Lines-020-710 diagram and in the detail pic above. Resistive connections to Init Device Select of Slot_B and Slot_C are tied to address lines on the 1:1 connections of the address bus. Ignore the "tails" pointing down toward the Logic Board...

For R1 and R2 values I'll have to get back to you. It's somewhere in the threads, likely over on TD. Original sketch for MechanicalDoodle shows the resistive connection setup for Init Device Select clearly. Neglected to put that detail in the AI file. Resistive connection for Slot_A is made on...

Been trying to get Slot_B clearly documented. You can probably figure the schematic out from This file, which I think is more akin to a KiCAD schematic than my plumbing:

Mine didn't, first rev. board, do the newer boards boot , but not the first?

Has anyone done the //c LCD type base for this or any other retro case LCD unit? My sketch doesn't show the horizontal bar the shielded ribbon cable should be running underneath in the //c pic. I think this stand would be perfect for IIci form factor case, which is too high for using any...

I was surprised to discover that Beige G3 will not boot without some version of personality card on board. Guess now is that the problem was my OS9 install? BG32U rackmount project has been bumped to BG3-3U form factor until I can make a left angle riser or hack a couple of cable based risers to...

Off today and tomorrow, so if you can note what info I have posted isn't clear enough and what you need in order of importance I'll start knocking things off that list. Need to pull the cardboard prototype and refine the AI8/PDF files. May want to set it back a skootch more if there's clearance...

My research notes are over on TD. https://tinkerdifferent.com/threads/twislot-pci-riser-and-comslot2-nic-repro-in-widened-cs-riser-form-factor.3607/page-3 I need to take a good look to refresh my memory, but I think everything you need is there? I need to pull my cardboard prototype out to...
