No worries on timing.  I really appreciate it whenever.  I'm pretty much on hold at the moment until the PCBs arrive next week, as that'll be when I start getting the timing variables right for the ST and Sinclair.  Might have to rework the PCBs I found out the other day too, should have put a pull-up resistor on there.. :)
