I'm not worried about processor compatibility (although I have personally
been down the road with the VAX-4000 line and how DEC violated their own
earlier Qbus specs because the newer processors got too complicated and
too far away from direct bus control... several older cards don't play
well with, for example, the TLZ04 controller because it grabs the bus
for too long and they timeout)
What I'm concerned about is OS compatibility. I have a mix of VMS 5.0,
VMS 5.5 and VMS 6.2 stuff here. Essentially, I want the newest stuff
I can get and still have the DEQNA work with it. Ultimately, through
DEC layered products or third-party products or whatever, I want to
have a Qbus VAX with TCP/IP over Ethernet so I can spin up various
older media and perform physical backups to a machine that can cut
CD-ROMs. I'd rather not push this quantity of data over a serial
line - it'll take a stunningly long time. I'm talking about a closet's
worth of old media (16MT9, RK05, RL01/2...) Several CDs worth. Not
what I want to push over 9600 baud.
Is there any sort of driver compatibility chart for VMS running around
anymore?
Thanks,
