See my comment on YouTube

I can't help thinking you're trying to tell us something, ... Is there a chip in the IBM PS/2 that works like this? I imagined it would all be handled as a serial interface using some sort of UART/SIO-type device with a buffer implemented in sofware ...

I'll look that up: maybe start here A.C. Norman  Faster combinator reduction using stock hardware  in LFP '88: Proceedings of the 1988 ACM conference on LISP and functional programming. At 26:25 on the ISWIM virtual machine implemented in the PAL compacting garbage collector?! This work Reynolds and others did was at MIT in Masecheusetts and Argonne National Laboratory ...
