 			pdp11_rp.c: added operations logging

 11	8-Oct-01	scp.c: added sim_rev.h include and version print

 			multiple outstanding interrupts caused the lowest
 			rather than the highest to be acknowledged

 			KW11L compatibility, needed for RSTS/E autoconfiguration

 8	4-Oct-01	pdp11_rp.c, pdp10_rp.c, pdp10_tu.c: undid edit of
 			28-Sep-01; real problem was level-sensitive nature of
 	   		CS1_SC, but CS1_SC can only trigger an interrupt if
 	   		DONE is set

 7	2-Oct-01	pdp11_rp.c, pdp10_rp.c: CS1_SC is evaluated as a level-
 			sensitive, rather than an edge-sensitive, input to

 			drive registers

 			non-existent formatters, fixed non-data transfer commands
 			clearing DONE

 5	28-Sep-01	pdp11_rp.c, pdp10_rp.c, pdp10_tu.c: controller should
 			interrupt if ATA or SC sets when IE is set, was
 			interrupting only if DON = 1 as well

 4	27-Sep-01	pdp11_ts.c:
 			-- NXM errors should return TC4 or TC5; were returning TC3
 			-- 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

 			scp.c:
 			-- added routine sim_qcount for 1130
 			-- added "simulator exit" detach routine for 1130

 			sim_defs.h: added header for sim_qcount

 3	20-Sep-01	pdp11_ts.c: boot code binary was incorrect

 2	19-Sep-01	pdp18b_cpu.c: EAE should interpret initial count of 00
 			as 100

	dec_dz.c: fixed bug in carrier detect logic, carrier
	detect was being cleared on next modem poll

	8 4-Oct-01 pdp11_rp.c, pdp10_rp.c, pdp10_tu.c: undid edit of
	28-Sep-01; real problem was level-sensitive nature of
	CS1_SC, but CS1_SC can only trigger an interrupt if
	DONE is set

	7 2-Oct-01 pdp11_rp.c, pdp10_rp.c: CS1_SC is evaluated as a level-
	sensitive, rather than an edge-sensitive, input to
	interrupt request

	6 30-Sep-01 pdp11_rp.c, pdp10_rp.c: separated out CS1<5:0> to per-
	drive registers

	pdp10_tu.c: based on above, cleaned up handling of
	non-existent formatters, fixed non-data transfer commands
	clearing DONE

	5 28-Sep-01 pdp11_rp.c, pdp10_rp.c, pdp10_tu.c: controller should
	interrupt if ATA or SC sets when IE is set, was
	interrupting only if DON = 1 as well

	4 27-Sep-01 pdp11_ts.c:
	-- NXM errors should return TC4 or TC5; were returning TC3
	-- 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

	scp.c:
	-- added routine sim_qcount for 1130
	-- added "simulator exit" detach routine for 1130

	sim_defs.h: added header for sim_qcount

	3 20-Sep-01 pdp11_ts.c: boot code binary was incorrect

	2 19-Sep-01 pdp18b_cpu.c: EAE should interpret initial count of 00
	as 100

	scp.c: modified Macintosh support

	1 17-Sep-01 pdp8_ttx.c: new module for PDP-8 multi-terminal support

	pdp18b_tt1.c: modified to use sim_tmxr library

	nova_tt1.c: modified to use sim_tmxr library

	dec_dz.h: added autodisconnect support

	scp.c: removed old multiconsole support

	sim_tmxr.c: modified calling sequence for sim_putchar_ln

	sim_sock.c: added Macintosh sockets support
