Most of these cannot see hardware upgraded at the logic board level.
These lower end Macs, unlike production towers; had fewer options.
What is the configuration specification of the iBook's logic board?
An upward limit on system upgrade is figured by hardware specs.
The CPU is fixed; so is the GPU. Certain speeds are built into HW.
Few could see CPU/GPU upgrade, w/ portable models. Few desktops
had the upgrade path built into them; rarely superseded these.
And the limits on hardware and software update/upgrade, are published.
The progression from system to system can be limited;
Study the question, which 'build model year' hardware can use what level
of Mac OS; then what you'd need to run required software. Reasonably.
Research what you expect from these older units; plan to leave them at
best last stage. ~ If the job/project is worth it. The tool, equal to the job.
Everymac.com site, Mactracker.ca database app, Lowend.mac site and other
sources of info can be very helpful. Don't spend a lot on dead-ends unless
there may be an upside to this. Restoring rare models with their OS, can be.
For each word here, I've written four others; then removed them!
Near seven-thirty PM here, in AK. Need to do other things.
