Fix divide of 0 on KS10 processor.
Fix write access for auxiliary processor memory.
Updated support new PIDP10 panel.
Allow eight Unibux ports on the TEN device.
Added GE DATANET-760 device to PDP6
Removed USER mode restriction for idle detection.
Added Data Disc 6600 Television Display System.
A user observed that the TS11 would not run XXDP+, even though it ran
fine with the PDP11 operating systems, VMS, and XXDP V2. I traced this
back to a conceptual error in the implementation of some magtapes,
specifically the TS11, RH11/TM02-3, and the PDP10 TU45.
The issues is that beginning of tape, and being positioned in front of
the first record, are not necessarily the same. Following BOT, tape
drives record a ID burst If high density and an inter-record gap before
the first record. When the first record is read backwards or backspaced
over, the tape ends up at position 0 but should not show BOT. Most
simulated tape drives did this correctly, but a few used sim_tape_bot()
as a shortcut for BOT, and it's simply not correct.
BOT should be set at ATTACH, by a successful rewind, and by any reverse
operation when the tape is positioned in front of the first record.
BOT should be cleared by any successful movement operation, except
rewind.
Start of support for PiDP10 front panel.
Moved interrupt checking from check_irq_level to clear_interrupt.
Pending interrupts now saved in IOB_PI.
Cleanup of KL10 Timer interrupts.
Minor code cleanup.
Added KS10 support.
CPU Redid instruction decode to improve performance
Triple-I display cleanup.
Normalized end of line to DOS/Unix.
KL10 FE, Cleanup issues with TTY devices hanging simulator..
Fixed errors in RH20 device.
RP and TU drives more independent of RH controller.
Devices that do single character I/O could be attached to non seekable
host OS devices (tty, pipes, etc.) and thus shouldn't count on fseek()
and ftell(). These DEVICEs on these simulators do single character I/O
and easily can update their POS REGisters to reflect how much data has
been emitted. Changing such a REGister will have no useful effect
when attached to a non seekable file.
