I used the 9.2.2 Unsupported G4 iso which I got off of hotline, the info is on one of the main pages here.

The factory cds for the 1993 release of Samplecell are on Macintosh Garden, by the way for those wondering about them

There were loads of third party discs as well

“Digidesign reckons there are around 26 Mac CD-ROMs for SampleCell” - August 1994

If we do add anything new I’d prioritize SampleCell discs as they technically do have connections to OS9/System 7 in a sense.

Good idea! I need to find myself some SampleCell cards as well...

I'm about to go on my journey of installing Mac OS 9.2.2 on my Powerbook5,4. What installation ISO should I use and do I need a custom ROM? The download links no longer work and I can't seem to find the custom ROM needed.

I’d say it’s fine to just for now to re-add what was already there before in terms of Sample CDs. No need to go crazy about dumping every single one of them accessible

Thank you very much Jon for the additional results.
It helps greatly with the choice of network hardware to use (switches or hubs up to 100M) and which ones to avoid (1000M and above)

Okay, I went through and set it to a bunch of different speeds. The OS9 side of things always connected at 10m/half, but I can set the port to 10/(half/full/auto) or 100(half/full/auto) and it seems to still be able to communicate, but if I set it to 1000/(half/full/auto) or Auto/(half/full/auto) it stops communicating.

That is an interesting information...

Are you able to test the other combination s(10M/full, 100M/half and 100M/full) to help understand if it is only the auto négociation or some speeds that the OS 9 driver cannot deal with?

Answering my own question; after doing some digging about, it seems like it really doesn't like the fast part of FastEthernet... Even though it recognized that there was a link, it was unable to get DHCP information from my server and the network port it was connected to autodetected a Gigabit connection. Logging into the switch and configuring the port to be 10M/Half Duplex allowed the Powerbook to both get a DHCP address and connect to the internet. Hopefully this information will help others - if you don't happen to have a high end network switch that allows you to configure individual ports, maybe a good ol' fashioned 10Mbit hub will do the trick, but I don't have any of those to test.

I don't know if this helps you at all, but I have a Powerbook5,4 and I manually entered IP info, but wasn't even able to ping the system (even though it said link was up) but I have it plugged into a fancy Aruba switch, so I created a switching profile that was 10M/Half Duplex and assigned it to the port that the Powerbook is plugged in to, and once I did that, I was able to ping the system. It is also able to get a DHCP address, which wasn't working before. A possible workaround might be to plug this thing into an old 10mbit hub or switch... I have to dig through my legacy stuff, but I don't think I have anything like that floating around anymore.
