Re: Fw: Vectrex Yokes

I am going to test this with an asteriods pcb really some (I just got an
asteriod cocktail today as a matter of fact) I think that the vectrex is
slow with blanking because of the hardware limitations (I will know for sure
as soon as I test this with the asteriods) The deflection circuit that I
made works great. I built 2 so far. One for x and one for y. I even ran my
vectrex on a wyse crt and It looks great also.

Thanks,

Fred
