Mostek 50240 part. I may even be able to do the 70/30
option. No promises, but hey, I'm good at this. May
have to be 2 chips for the 70/30 option.

If you want it to replace old 50240 chips, then be sure that it can be 
externally clocked.  Some list members have talked about doing a similar type 
of thing, but using a fixed-frequency master clock (such as a CPU clock 
crystal).  This would be useless in most repair applications, not to mention 
any DIY app where you might want to modulate/vibrato the master pitch, or 
just have some simple master tuning control.

Please keep us posted on your progress!
