I think you mean 21.1 cm x 13.1 cm = 8.307 in x 5.157 in = 9.778 in diag = 77.2 dpi cm instead of mm.

You would need to drill through the transparent piece and the plastic of the subframe? The alternative to drilling or cutting is melting. Heat a metal pin (with soldering iron?) sufficiently that it can be inserted into the plastic. Is that possible? Will the hole that is created snuggly hold...

I think it would look cleaner without the transparent plastic piece. The JB Weld might perform better if it's thicker but I have no data or experience (more JB Weld probably means more elongation?). It's a tossup. If JB Weld doesn't stick to the plastic well then it would be nearly useless...

The error may be up to less than an 1/8 of an inch which is not bad since you are measuring in eighths of an inch. bc <<< 'scale=10; (sqrt((5+2/8)^2 + (8+4/8)^2) - (9+7/8))*8' .9249648104 Remind me, do 68K portables have square corners or round corners? Round corners make it difficult to...

The vertical and horizontal resolution also needs to be known to calculate the DPI, but this info can be gathered from the Mac's specs. Alternatively, you can also just use the horizontal number of pixels and width or just use the vertical number of pixels and height. Using the diagonal is...

Tape some paper to the side of the metal drive bracket, install the metal drive bracket, and stuff JB Weld between the fins and the metal drive bracket. The paper should stop the JB Weld from sticking to the metal drive bracket? Instead of paper, use a thin metal plate? Something less thick than...

Thanks for that. I've attached the result of parsing that dump with my parseOFlspci command (included in the "lspci for Open Firmware.zip") which uses lspci. I welcome dumps from any Power Mac or ANS that has different results. Does AIX have pciutils with lspci? I suppose someone could port...

MPW's DumpPEF is a command line utility and therefore scriptable which is useful if you are researching multiple PEFs. It produces text output that can by processed by scripts or compared.

My MacROMan fork has all the New World ROMs (except maybe the ones created to boot System 7 or 8 on New World Macs). I have a script decompressrom.sh that has a command dumponerom that uses the tbxi dump command to take apart the ROMs. https://github.com/elliotnunn/tbxi It then uses MPW's...

Anyone with a serial connection to Open Firmware able to get PCI info using #50 ? https://www.dropbox.com/scl/fi/ddwv1zeddpydkzrykl4kl/lspciForOpenFirmware.zip?rlkey=rujv8sbhb8v4ehk9b845bd3k1&st=qwg4xfv2&dl=0 Another method to paste scripts into Open Firmware quickly (avoids...

There appears to be some voids on the underside of the subframe assembly (shown in this image on the left side) that could be filled in with putty to add reinforcement?

There's a Mac OS X driver for the apple53C8xx "IONameMatch"=("apple53C8xx","Apple53C875Card","ATTO,ExpressPCIProLVD","ATTO,ExpressPCIProUL2D","ATTO,ExpressPCIProUL3D"), "CFBundleIdentifier"="com.apple.driver.AppleSym8xx", "IOClass"="Sym8xxSCSIController", "IOProviderClass"="IOPCIDevice" For...

There was a video posted at #23 But I think this one shows it better: The subframe that holds the hinge also holds the motherboard.

The GitHub points to a wiki and a Discord. We can answer all questions in the Discord. DingusPPC is a work in progress so lots of stuff doesn't work (networking) and there may be issues with audio or other emulation in certain areas. For example, SCSI works in classic Mac OS but might not work...

I think #6 explains that we have a good copy of that bad rom. The ROM has version 2.26b6 and should have md5 = d1d3720c38143eb2bac86b8393318529 As for what I'm doing: I'm working on ANS emulation in DingusPPC. Maybe one day it will boot AIX or macOS. I am working on the emulation of...

Your first post says JB Weld Epoxy does not bound well to polycarbonate (poor chemical bond). But what about using JB Weld Putty for mechanical bonding? Maybe it can be used instead of metal plates/wires. You can drill into it to add screws or pins or other fasteners. If you melt wires into...

The app in my example was locked! After unlocking it, -d does work to remove (or hide) the FinderInfo. So both of these will remove the FinderInfo (or set it to zeros which hides it from the xattr -l command): sudo xattr -d com.apple.FinderInfo "ZTerm 0.9" sudo xattr -wx com.apple.FinderInfo...

The xattr command can't delete FinderInfo because in Mac OS X, on an HFS or HFS+ or APFS partition, FinderInfo is not an extended attribute or it contains info that cannot be removed - it can only be changed (using SetFile or xattr or other command). dumpxattr () { local thefile="$1" printf...

The file in my example has a resource fork without the type/creator that is in the FinderInfo. I think a correct implementation would not attempt to do any parsing of the resource fork. Metadata is ALWAYS externally stored regardless of whether a resource fork exists or not. It appears that...

It would be preferable to be able to have tension go all the way from the top of the rib to the other side so that new cracks can't happen anywhere in-between. I like the part at which shows how the hinge slides into place which perfectly illustrates your point that the ribs are part of the...
