That looks like a much more elegant solution than mine. I’ll try it on my Rev G board to confirm it works with my network.

No - most (cheap) SIL3112-based SATA cards have insufficient capacity for the preferred Mac firmware (SeriTek). Furthermore, the SeriTek firmware accepts only 3 types of 4Mb PROM (PM39LV040, MX29LV040 or AM29LV040B). If you're only wanting to use OSX and not MacOS9, the WeibeTech firmware will...

Ideally, you'd hope. I've not been able to get an outboard transreceiver to work with the B1 via AUI regardless of JP1's setting. I've not been able to dig up schematics for these things. Since I'm only interested in TP, my hack is sufficient .. so I've not bothered to reverse engineer the...

A footnote to the above change is that AUI with outboard transceiver no longer works. But who would care?

Sounds more like lateral thinking. Congrats! How did XPostoFacto figure in? Did you apply its patches from OS9 on the real machine after the virtual install, or did you use XPF in the VM to assist the virtual install?

I've tried various SATA-IDE adapters with G3 DT and MT, and they're either unusable or at best unreliable. The best and fastest way to hook an SSD onto this class of machine is to use a PCI-SATA adapter -- see Xodium's thread...

One simple way to get RJ45 to work on the Rev G board is to: remove R45, a 0Ω resistor tie the end of R45 closest to the NIC controller (with trace to pin 72) to pin 7 of U20 which is the OV rail See annotated photo:

Deciding not to rewire with thin net, I took your suggestion and took a look at pin 72, the AUI/TPI SELECT line, on both the rev B1 and rev G boards. On the G1 board, pin 72 is tied firmly to 0V vis a 0Ω resistor - hence twisted-pair goodness albeit only half-duplex. Whereas on the...

Yes, these beasts are challengingly temperamental; there lies their attraction to some of us! OpenFirmware deficiencies are a real problem for OSX although OS9.2 is somewhat better placed. But your hardware config is a major factor too. I have a desktop and a tower so I've done a perhaps a half...

For the Beige G3 you need to do the XPostFacto dance: https://eshop.macsales.com/OSXCenter/XPostFacto/Framework.cfm?page=XPostFacto3.html#machine Jaguar installs OK, but in my experience Tiger is best for this machine. Also, beware of the CF to IDE adapter. Version 2.4 of Open Firmware on...

I’ve used a couple of the Rev G version of these NICs in Mac IIcx and IIci, and I’ve always have trouble with RJ-45 10Base-T. Operating through an external AUI transceiver is fine but direct RJ-45 connection mostly fails. People have reported these NICs don’t sync with modern 100/1000 switches...

I'm fixing up an SE/30 and my brightness pot has also been munged. In my case, ~180KΩ is the value needed for adequate brightness. Your 18KΩ seems very low (for a 1MΩ pot) - was this a typo? My SE/30 also had a arcing CRT due to it the nipple breaking at the end of the neck and hence bye-bye...

Github's a fine suggestion. And don't overlook the collected wisdom of the ROM gurus such as Doug Brown, Steve Chamberlin, Rob Braun et al: https://www.downtowndougbrown.com/programmable-mac-rom-simms/ https://www.bigmessowires.com/category/rom-inator/ http://synack.net/~bbraun/...

Sadly, I don't have a Pi and should .. because this is yet another case where a Pi's handy :). I also came across https://trmm.net/Mac-SE_video/ using the same technique.

I'm restoring an SE/30. The logic board needs recapping but the analog board and PSU are in pristine condition. So while I'm working on the logic board, is there a way of testing the video generation without the logic board being connected? Can the video signals be fudged to display a blank...

You'll need something on the other end of the line to return characters. Connect your machine to another through a null modem cable. Make sure the speed and encodings match. I occasionally use Zterm on my SE to connect to a serial line (e.g. serial console) of another machine to log-in or get...

Yes - burn a CD-R from the ISO. But be aware that it may be picky about what CD media it will read. My B&W G3 has a DVD drive that doesn't like CD-Rs and I need to burn CD ISO images onto DVD-R media. Your machine, a PowerMac1,1, can't boot from USB but will be happy with a CD/DVD. Later...

10.4 Tiger is what you want. Earlier versions will work but aren't as good; later versions require at least a G4. I run Tiger on my PowerMac1,1 (along with MacOS9.2 and Debian8 and OpenBSD7).

Reboot with the command-V combo held (for verbose boot) and post a video. And/or reboot with the Shift key held forcing a safe-boot to rebuild the kernel extension cache.

So I got another 3112 card - this time for my B&W G3. Yes, it's not an Old World machine but I wanted to see the performance on a 100MHz PCI bus. And also for giggles, I tried a spare SATA 2TB drive (WD Blue) I had sitting around. I got 60-plus MB/s read performance and about half that for...
