9	6-Oct-01	pdp11_rp.c, pdp10_rp.c, pdp10_tu.c: rewrote interrupt
			   logic from RH11/RH70 schematics, to mimic hardware quirks

			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
