The Question is:
Is there a QBUS Ethernet card which supports 100Mb fast Ethernet?
If so can it coexist with older 10 Mb card in VAX 4000 of different models?
The Answer is :
Compaq does not offer such a 100 megabit per second Fast Ethernet Q-bus
controller, though a third-party might. Given that the Q-bus could not
drive the Ethernet at anywhere near this speed, why bother? (The fastest
(measured) performance (that the OpenVMS Wizard is aware of) among some
of the various Q-bus peripherals found in various members of the Q-bus
MicroVAX series is circa thirteen (13) megabits per second.
