At 1/4" thick, there's a chance it's a DF32 platter. I don't remember
how large the hub hole is, but at first glance, and with the PDP-8
suggestion, that's what I'd have to guess.
I have never seen an RF08 platter, so I don't know how physically
similar they are.
One thing to check for - is there a band of tape or other blacking
material around the rim of the disk with a gap of a few mm? The DF32
has just such a gap for the rotation sensor. Not sure about the RF08.
