Good deal:-)
I'm still wondering what a B500 really is. How does it differ from the
Commodore P500 and especially the 600 models? I've of course read the SWoC
pages, but they are not very clear about this machine.
Is it possible that the B500 is a 600 with just 1MHz clock? Or are there other
differences? And, while I'm asking curious questions: Is the 1MHz clock rate a
proven fact, or a rumor?
The picture at

shows a B500 on the left side. However, the mainboard looks exactly like that
of the Commodore 600 - including the oscillator case.
Does anybody know where to download the kernal ROM for a B500 from the net for
comparison purposes?
Regards
Uz
