Was trying yesterday to give the clock running at 16mhz.. But ended up with odd issues like this..

I also think there is a missing pull-up on the 16mhz booster causing floppy issues. This was even more problematical because it seems the ZIF socket I had in my H5 for testing 1772 chips was also causing floppy issues :roll: so I should probably look for a better ZIF socket...


Next problem is the JTAG adapter which @Icky somehow lite up bright orange when I think I plugged it in wrong.. Looks like a track got a tad on the warm side..

So while I was at my girlfriends today, doing the monthly ASDA shop... I was stood there staring into space, as one does in such situations, and some something struck me.. ( no it wasn't my girlfriend throwing a tin of beans at me for not paying attention and putting it in the trolley ).. I realised I had some logic which would work fine at 8mhz but not 16mhz.. I'm not sure why that logic was there, but it was slowing down the flashyclock bus enable buffers :shrug: so anyway.. we now running 16mhz !
