I became the proud owner of 2 7500s. Their condition was fair. I took both of themm to make one laptop.
I decided to make linux my only os on the machine. The install went great. X windows didn't work on the first attempt. To make X windows play nicely you need to add the following kernel option:
During the install at the boot prompt enter linux vga=791
During the first boot of the system you will need to pass vga=791 as a kernel option
Once booted you will need to add the option to grub.
That's the only gotcha I found.
