6.08 you mean (never heard of 6.8 ).
The answer is no, you need 7.1 with an enabler up to 7.6.1.

6.08 you mean (never heard of 6.8 ). Or perhaps its even 6.0.8

I'm curious... I know that the LCIII can't run system 6, but I'm curious as to why 68k macs that can run system 7 can't run system 6. Does it have to do with a hardware limitation (memory management, rom setup) or is it a limitation put in place by Apple that could be reverse engineered?
Sorry if this has been discussed ad-nauseum.

I'm thinking it may be something to do with the 24 bit / 32 bit addressing as it seems that the System 6 compatibility cut-off is around the time when 32 bit "clean" machines were produced.

This was also the time the various System Enabler extensions started coming out, the idea being rather than do a new release for every machine, just put all the new drivers and patches in the enablers.

Sorry 6.0.8 is correct. I can't see why a 25MHZ 030 LCIII can't run system six when a IIci with the same processor can and a IIfx can too. It has to be a memory (72 pin in the LCIII) thing or an intentional Apple limitation. But it is a shame because an LCIII on system 6 would be very fast.

About 10 years ago I played around with a copy of System 6.0.8 on my LCIII. I can't remember what I did exactly, but i hacked the crap out of it in ResEdit. I was only 12 or 13 at the time. I think i copied crap out of a 7.1 install. It almost booted to the Finder before coming up with some error about System 6 not supporting the hardware. I'll have to try again some day - I honestly can't remember what I did.

The LC I was System 6 compatible, why not find a way to flash the LC ROM onto an LCIII?

Okay then, just use an LC with the 25mhz processor.

...the LC didn't have a 25MHz processor.

I meant to say "Use an LC with the LCIII's processor."
But wait, I forgot the LC has an '020. Just forget it...

The LC II has an 030. However, as some have pointed out, the architecture of the board is far different on the LC III.
An LC III needs an enabler to run, meaning it must use System 7.1 or later. You won't find the code necessary to support the machine in 7.0.1 or any version of 6.
Your best bet for running 25MHz System 6 is to use a Mac IIci. Accelerators for the LC and LC II may work but the drivers may require System 7, so watch out. (Note that the LC can run System 6.0.6, 6.0.7, and 6.0.8 while the LC II can only run 6.0. 8) .
