Answered my own question. Going to format a CF card in HFS+, clone an OS 8 disc to it via Disk Utility, use a PCMCIA CF card adapter to run the installer on the 5300c and install it onto the HDD.

If anyone has a cheaper way of doing this, please let me know. I figure this is going to cost me $30, which for me, is quite a lot (since my allowance is only $40 a month) for just an experiment. Plus, $30 could buy me quite a bit of vintage Apple things. }
