PowerBook 540c - Did a thing (OS 8.6)

Although I like to stay true to my 68K roots, I recently acquired a PB 540c with the Apple 603e 100MHz upgrade card. So decided to take this up to OS 8.6, because why not? :)

Although I don't have much interest in running PPC on a Blackbird, seeing 8.5+ on one always seems so exotic.
Why not try 9.0.4?
I'd be interested to see some benchmarks with Norton System Info 3.2, I guess performance is going to be even less than a PB5300/100 considering the 16MHz peripheral bus (vs the 5300's 25MHz).
 
Yeah that looks pretty cool. I also finally got a PowerPC card but I am still running 7.6.1. I think I will always be a System 6/7 person.
 
Does the bus-speed make the PB540c noticeably slow? Try running Marathon and see how that goes.
It would be the same 33MHz CPU bus as on a PowerBook 5300, 1400 or Duo 2300. So RAM and ROM access should be identical clock for clock.

According to the Dev Notes for these models the 16-bit ‘030 peripheral bus runs slower on the 500 series (16MHz) vs on the PB190 or the above mentioned PPCs (25MHz). So, I’d expect Marathon to run slower than on a PB5300/100, for example, since it wouldn’t be able to push as many pixels out.
 
I am interested in pushing this to 9.0.4 next. But can certainly say it is noticeably slow with 8.6, which isn't a surprise when considering the slow bus speeds.

I think maybe what I want to see is if it would be possible to watch a YouTube video somehow on a Blackbird. I haven't actually done much research to see if anyone has tried this with WowTube, or a more modern browser, etc. Anyone have experience with this?
 
What kind of medium are you using to upgrade each time? All I had to upgrade from 7.5.5 to 8.0 was the built in Floppy drive and it was quite the headache 😅.
 
Yes 100%, go with BlueSCSI v2 if you can. Makes doing stuff like this just so much easier. Then on macintoshgarden.org, you can easily get all the install media up through OS 9.2.2.
