They're around. I had one when I was little and it was ok but kind of
clunky. The box was odd, it only had 16 (maybe 18?) bits wired on the
backplane and the power supply was a linear rock if I remember right.
I imagine 16 bits. It probably had an 11/02 processor just like
the TERAK. 18 and 22 came later.
Still, it ran Rt11 pretty well. But an 11/23+ would give you the VM: ram
disk driver that allowed you to just copy the whole OS to memory, boot,
and run fast!.
I know it ran HT-11 which was supposed to be a custom RT-11. Would it
run regular RT-11? Was the H-27 fully RX01 compatible?
