251Porting
252-------
253This board support package is written for a 68360 system similar to that
254described in chapter 9 of the Motorola MC68360 Quad Integrated Communication
255Processor Users' Manual.  The salient details of this hardware are:
256
257        25 MHz external clock
258        DRAM address multiplexing provided by 68360
259        8-bit 180nsec PROM to CS0*
260        4 MBytes of 60 nsec parity DRAM (1Mx36) to RAS1*/CAS1*
261        Console serial port on SMC1
262
263The board support package has been tested with a home-built board and with an
264ACE360A board produced by:
265        Atlas Computer Equipment
266        703 Colina Lane
267        Santa Barbara, CA 93103
