Me too Lester.  I went on to add another 4k of static ram to it, and built 
the video it needed out of ttl parts, making it into a commercial 
production tool that was used for at least a decade at KRCR in Redding CA. 

It took the finished commercial, which was then dubbed onto a copy of a 
master tape that had the cue tones for an automatic station break machine, 
and replaced that dub operation which was a huge quality loss back in 3/4" 
u-matic vcr days, and laid a new digital academy leader in 8.8 format and 
the cue tones right on the finished tape, saving a dub generations quality 
loss.  That improved our on air look and probably bought us 3 points in the 
ratings book.

BTW, welcome to the list.
