Mark Pizzolato 6339af2dc4 PDP11: Fix to correctly set PS value on CPU reset to reflect the model specific ways real hardware behaved. (from Bob Supnik) 
Here's a PDP11 SIMH bug as old as the simulator itself: the reset_cpu routine sets the PS to 340 (interrupts disabled). This causes some versions of Lunar Lander not to work. In fact, the initial state of the PS is not architecturally standardized:

      04: cleared (from schematics)
      05: cleared (from manual)
      20: cleared (from schematics)
      34: cleared (from schematics), set to 340 on boot?
      40: cleared (from schematics)
      44: cleared on init, set to 340 on boot (from schematics, manual)
      45: cleared (from schematics)
      60: cleared (from schematics)
      70: cleared (from schematics)
      T11: set to 340 (from spec)
      LSI11, F11: 4 mode behavior (from memory on power recovery, cleared on GO, 340 on boot, mode 3 undefined)
      J11: 4 mode behavior (from memory on power recovery, cleared on GO, 340 on boot, 340 on jump to  custom PROM)

The story seems to be this. All non-VLSI PDP11s used TTL chips to implement the PS, either discrete flip-flops, or 4b registers, or both.
Starting with the first system, the 11/20, they were wired clear on the processor INIT signal (power-up or front panel START switch), so that all internal state started as 0. This worked fine, because START also reset the Unibus and cleared all interrupt enables. So even though the processor was as IPL = 0, no interrupts were possible. Then along came the LSI11...

The LSI11 implemented a line-time clock with NO INTERRUPT DISABLE. Thus, if IPL was left at 0 and a bootstrap routine from a slow device was started (e.g., a floppy drive), the clock would tick, and an interrupt would occur, before the bootstrap routine finished. Because no vectors were set up, the processor would crash. So the LSI11 started the practice, carried over to all later PDP11 VLSI chips, of setting the PS to 340 before jumping to a boot ROM.

The T11 did this in all modes of startup, because its only startup behavior was to jump to a "boot" routine. It did not have a console of any kind.

Accordingly, it appears that the cpu_reset routine needs to set the PS based on the processor model. Further, all boot routines need to set the PS to 0 or 340 based on the processor model. (It's probably safe for boot routines just to set the PS to 340, but it's not technically
accurate.)

- Fixed loopback processing to correctly handle forward packets.
- Fixed interrupt dispatch issue which caused delivered packets
(in and out) to sometimes not interrupt the CPU after processing.

- Added dropped frame statistics to record when the receiver discards

cause receive processing to never be activated again if we don't
read all available packets via eth_read each time we get the
opportunity.
- Added the ability to Coalesce received packet interrupts. This
is enabled by SET XQ POLL=DELAY=nnn where nnn is a number of
microseconds to delay the triggering of an interrupt when a packet
is received.
- Added SET XQ POLL=DISABLE (aka SET XQ POLL=0) to operate without
polling for packet read completion.
- Changed the sanity and id timer mechanisms to use a separate timer
unit so that transmit and recieve activities can be dealt with
by the normal xq_svc routine.
Dynamically determine the timer polling rate based on the
calibrated tmr_poll and clk_tps values of the simulator.
- Enabled the SET XQ POLL to be meaningful if the simulator currently
doesn't support idling.
- Changed xq_debug_setup to use sim_debug instead of printf so that
all debug output goes to the same place.
- Restored the call to xq_svc after all successful calls to eth_write
to allow receive processing to happen before the next event
service time. This must have been inadvertently commented out
while other things were being tested.
pdp11_xu.c: (Mark Pizzolato)
- Added SHOW XU FILTERS modifier (Dave Hittner)
- Corrected SELFTEST command, enabling use by VMS 3.7, VMS 4.7, and Ultrix 1.1 (Dave Hittner)

sensitive, rather than an edge-sensitive, input to
interrupt request

drive registers

interrupt if ATA or SC sets when IE is set, was
interrupting only if DON = 1 as well

- extended features is part of XS2; was returned in XS3
- extended characteristics (fifth) word needed for RSTS/E
pdp11_tc.c: stop, stop all do cause an interrupt
dec_dz.h: scanner should find a ready output line, even
if there are no connections; needed for RSTS/E autoconfigure
