Daniel,
hacked from the
software
Yes, can (get a kit with SMT work done)
OK, that?s the answer I needed;
If I want to put one of these in a KS10, can the parity lines be (the KS10 uses them as two extra data bits) or are
they hard-wired to
parity?
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
software stack.
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.
regards,
Joerg

As far as I know, only the (disk) RH11-C uses the extra two bits; The tape RH11 and all
other options are unmodified PDP-11 stuff.
In my case, I would need to emulate an RH11-C, a Chaosnet, and an IMP interface if
possible.
Emulating DZ11s as TCP targets as well would be nice, but I have physical DZ11s if there?s
not enough capacity left.
