Difference in memory and IO organization. the 4000-300 is definately faster
if your loading the IO. At light loads it's hard to tell one from the other
if they are both running VMS.
<But both are very fine boxes, if you like the QBus, you really should get
<4000-300. 4000-500 port might take some while, the CPU is a bit difficult.
the BIG advantage of the Qbus boxen is IO extension for serial lines and
all manner of non scsi interfaced things.
