only had to slice the PSU side off for this build, but then random bits of metal and a ton of JB weld to fill in all the gaps. printed a cover for the IO shield area as thats where i put the sff power supply. The case is actually a 15x15x7 junction box that had to be cut with a grinder

In this shot it looks like you had the same kind of offset slot problem I have, in the other not so much?



Difficult to show the 3.8mm offset required to fit the 9500/PEx boards. But easy enough to see that the rightmost slot edge will be a perfect overlay for the resultant gap.

After the grlf flies home Sunday I can get down to the grinder/cutoff nitty gritty.

Crosshatched sections show the absolute minimum I could do in case mod, but will be doing a bit more to fair the new black slot section in across the back. DB-25 Port A will work for the SCSI connector if I file the ear out a little, even less as shown for the speaker/microphone ports above ALARMS. The indented slots for the backplane cover plate extensions had to be done, so opening things up a bit more than the crosshatched indications will be done.





These two shots detail the further cutback I need to do for to the tan plastic Netra board supports for fitting the PEx mobo. Will work nicely supporting the Board's Memory/ROM slots.

I added an about screen to my FireJam project

My MARCHintosh has been busy, some year I'll join in GlobalTalk, but for now I'm using it as an excuse to work through the backlog of old Macs I have sitting on shelves un-inventoried...

So far:

1. I finally put together my Pico Micro Mac — the V2 version that required some extra soldering work. Fun, definitely enjoyable, especially as a Raspberry Pi Pico connoisseur!
2. My Dad and I were lucky to get a Docklite from Juicy Crumb, and so we installed it in his old iMac 2010 21". Excited to hear they're also working on a way to get the Combo drive working—he will actually find a lotta use for it, as unlike me, he's okay with 1080p displays still
3. I just finished recapping an Xserve G5 PSU (huge thanks to House of Moth for assistance!), and now I'm trying to figure out the best way to do lights out management of the G5 — I know the Xeons had ipmitool support, but it doesn't look like the G5 has a BMC? Shucks.

In the coming weeks, I hope to finish up a video I've been working on a while, on my favorite Mac laptop of all time (and some runners-up), with a few special guest appearances. Then if I can finish it, a video on how I made my first YouTube video — using a similar FireWire + G4 setup I used back then... and then showing a neat new tool that might get some of us to pull our old DV cameras out of the closet! (Hint: it's called the Firehat!)

I've been enjoying all the other projects I see on here, the live streams, etc. — and with this leading up to Apple's 50th, it's been a great month of nostalgia for the computers that I grew up using!

Someone on the Wireshark Discord pointed me to this GitHub repo with a very complete Lua plugin for decoding AURP traffic — legacy AppleTalk.

It's been rather interesting to sniff "vmenet0" of my virtual Quadra 800 acting as an Apple Internet Router. Especially with 100+ nodes in the GlobalTalk network. I can only see the traffic going in and out of my node, and since most of us are directly connected to other AIR nodes, it's pretty much limited to traffic I'm generating like browsing file shares, sending or receiving routing updates, pinging other networks and devices, etc. Nevertheless, AppleTalk is a very descriptive protocol.
