Well, I could do that, in these past challenges I always tried to accomplish something on a PPC machine that I was doing on a Intel machine.
Currently my lockdown plans where to learn Assembler on my 8 bit Atari's and fiddle around with trying to make music on the 8bit 130XE and 16 bit Atari 1040STe but since I purchased a M-Audio Firewire Audiophile interface I could now link them to the G5.
I was trying to get Eclipse running a while ago on the iBook 14" in order to create an IDE for 8bit Assembler, will see if I can pick that back up.
I do have a DevOps course I have to start also for which I would need Intel stuff probably but will see ... I've learned from the past that with patience one can achieve his/her goals on a PPC machine also and most of the stuff is connecting to a cloud box which every *NIX machine is able to. (and ok Windows too

)
The G5 has already replaced my MBp connected to a 30" Cinema Display for watching movies/tv series so that's one tick on the checklist.
