Several people asked to make UniBone PDP-10able, it should be not problem.
UNIBUS PA,PB are (like all other signals) just pins on a GPIO
multiplier, no interpretation is done in hardware.
On software side the PRU must sample 18bit instead of 16bit for DATA,
then lots of "uint16_t" must be changed to "uint32_t" in the whole
Not clear what to do with existing device emulators: did DEC construct
18bit mutants for a few PDP-11 peripherals to run them in KS10?
UNIBUS on a PDP-10 makes only sense to me if the big pool of PDP-11
peripherals can be used directly.
