Cine/VB game release dates

I'm slowly trying to fill in the month of release for the
games in the bronzeage list, and thought maybe someone on
this list would know 1) when the cine - vectorbeam split
happened and vectorbeam's Space War came out, 2) when
they merged again, and if these release dates are right
