GROWTH MOTION OBJECT HARDWARE REQUESTS
Engineering Conference Room
Thursday, October 6, 1988  at 2 PM

Many people have expressed their interest in using the new growth motion
object hardware.  At this time, Quest is the only implementation of that
hardware.  

The Quest hardware has a horizontally scrolling playfield of 64x30 stamps
that is visible in a 32x30 window on the left hand edge of the screen.  On the
right hand edge of the screen is a 10x30 strip of alphanumerics.  Each scan
line of the scrolling playfield has its own HSCROLL value.  Both playfield and
alpha pictures have one word specifiers.

Overlayed above the playfield, are the growth motion objects.  The interface
to the programmer is very similar to that used in other hardwares except that 2
new parameters (MOSIZE and MOPRI) have been added to specify the size and video
priority of each object.  These motion objects are built up in two 8-bit deep 
frame buffer that can be swapped every 1, 2, or 3 frames.  Each frame, about
1 1/2 screens of motion objects can be drawn in the frame buffers. 

Quest will soon start PCB layout, so if anyone has requests or ideas about 
additions or features to add to the current board, please attend the meeting 
at the time and place given above.  Since technician and engineering time is
at a premium now, if your suggestions or ideas are not heard from at this time, 
it may significantly delay when these new features were available on a working
hardware.
