In case anyone was interested in an FPGA VAX implementation

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.

I found myself wondering what it would take to put this, RAM, network, and a SD
Card “Disk” on a Q-Bus board. :-)

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.
