To continue the exploration on overclock,
I have assembled a proper clock synthesizer which can generate any clock
from 2.5M to 10M. It uses a 74HC4046 PLL chip, a 10 divider and a 250kHz
to 1MHz source clock.
So this will let me finely tweak clock period to try and estimate safe
overclock.
Good news is it's going to rain for a few days here, so I can spend time
inside & improve M100 CP/M by:
- increase Directory size from 256 entries to 512.
- make Import/Export "user" friendly. ie for user area to remain
constant before & after.
Thought I'd let CP/Mers know this so they can

I'll vote for an expanded
