6303 speed note

The speedup the 6303 provides over the 6803 will probably be smaller than the 6309 vs 6809.  Several of the 6803 opcodes were a clock cycle faster than the 6809 to begin with, and many opcodes aren't any faster at all.  But somewhere between 10% and 20% would still be pretty significant, especially when that is combined with the new ROM.

MESS is a mess

I had hoped to post some videos comparing the M6803 and HD6303 on the MESS MC-10 emulation.  That doesn't seem to be an option at the moment as MESS locks up the machine after a few minutes.  It turns out that the recent build is doing this even without any of my changes.  This may be an issue with the current Windows 10 update I'm running.  The MESS timing also appeared to be off, as the 6303 was running slower than the 6803.  That should never be the case.  I could see less of a speedup than originally expected, but it should never be slower running BASIC.
