In case anyone was interested in an FPGA VAX implementation
http://mail-index.netbsd.org/port-vax/2021/07/03/msg003899.html
And/or thoughts on 64bit/FP & multiprocessor enhancements :-p

Indeed. If only someone could get him a copy of DEC's AXE suite so he
can test it properly. Anyone have that available?

I think this is fantastic, but getting the CPU running is only the
start. I'll be curious what/how storage emulation goes, and
networking. Bonus points for sync serial that can run a DDCMP line to
vintage machines.

Adding a Qbus to it would certainly offload the work of implementing
storage - just put it on the user to find a Qbus SCSI card or a KDA-50
or a Qbone or whatever and you wouldn't have to worry about OS drivers
or (alternately) mimicking a vintage disk controller.
I would hope it would use its own RAM. No point in forcing anyone to
use vintage RAM.
For convenience, it would be nicer to have some sort non-spinning disk
rather than a $$$ vintage controller.

Two SD card disks. I many not have used a VAX but I still remember using
a single floppy drive to copy files.Why not a real solid state drive?
Real I/O devices with DMA are needed and real media storage for all the
virtual memory swapping that may go on.
