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. Ben.

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. -ethan
