The CD seems to be lost, but I found two old diskettes with the boot and system image. Out of curiosity I booted them on a fairly modern hardware. Result: it still works in runlevel 3. Amazing!
I’ve read somewhere (but can’t find the link again) that the geeko changed side for marketing reason.
As most people read from left to right, the old geeko seems to go backward (in the past). Changing it to the other side gives a much more positive image to the company (geeko walking forward, to future and innovation).
I guess this theory is true for most company logo.
