[HECnet] VS4000/90: Up and running!

In the 1287 that pin is named R/W when the chip uses motorola style timing (MOT connected to Vcc) and WR when it uses intel style (MOT connected to GND). Check the DC1287A datasheet for the gory details. Now the MOT pin is not there in the 1267 (it is used to signal a "wake up" condition), so it doesn't look to be completely compatible with the 1287.
