What kind of sync signals does the AL250 accept? Just H and V separated? 
If so, it's wise to include one of those Sync-Stripper-ICs too which is 
able to generate the separated H and V out of a

* Color Composite Video Signal
* B&W Composite Video Signal
* "Composite Sync" (H+V mixed)
* "Sync on Green" type signal

Many "vintage" systems don't have H and V separated like the CoCo3, e.g. 
my French RGB PAL CoCos and MC-10s.
