Has anyone tried using a motorola MC6839 floating point  R
OM                         OM chip with a Coco 3
using OS-9? I was going through an old data book and came accro   ross this chip
 . It
says that it is ideal for use in                     can be used with real time
 and multitasking systems, and it is
position independent and re-entrant. I br  am curious since the coco could use a
 ll
the help it could get in terms of speed.

Also has anyone tried using the MC6844 Direct memory access controller (DMAC)
to interface a videocard with a coco? Of cousr  rse if this was to be used with
 o
s  OS-9 only contiguous blocks could be used to
         new device drivers or even wores   rse more mods to CC# 3IO, GRFDRV, WI
 NDINT,etc.
would be needed. But i from my glancing over the book (found it while getting
reference books for studying for finals) it seems like a possibility. Or am
I just suffering from lack of sleep?
