Bubble memory was the coming thing in 1978, as was the Space Shuttle.
In the mid-1980s my hardware-focused friend acquired a bubble memory card from a place where he was working; they'd got it for evaluation a couple of years before. He ended up building it into a system with a T-11 (PDP-11-on-a-chip) microprocessor (the motherboard containing which was acquired from the same source, I think) for experimental purposes

You would not need much of a chip to put PDP-11 onto. My first job was VAX. My second PDP-11. Quite a step down - especially as the VAX was government and PDP-11 was finance.
During my job I remember new Vax2 being installed. A whole 1 million operations a second. I saw the same model in the Smithsonian museum in Washington 15 years later(1999) - it was used on the space shuttle.
