I looked at it at MacWorld, when it's running things really seem to slow
way down .... we were trying to figure out how they can sell a $395
NuBus Master without lots of VLSI (and hence time to market etc) ....
we finally figured it out .... it's probably not a NuBus master and
 every so often it interrupts the Mac II and the Mac wakes up and copies
the TV data from a RAM on the board to the screen - hence the cheap cost and
the slow keyboard performance (they probably copy it at interrupt time!)
it also explains the low resolution which wont be likely to get much
better (without DMA) ... a neat hack but I think i'll pass
