2074                         - ASR shift count > 24 mis-set GTF
2075                         - effective shift count == 32 didn't work

2101 15      23-Oct-01       pdp11_rp.c, pdp10_rp.c, pdp10_tu.c: fixed bugs
2102                            error interrupt handling
2103
2104                         pdp10_defs.h, pdp10_ksio.c, pdp10_fe.c, pdp10_fe.c,
2105                         pdp10_rp.c, pdp10_tu.c: reworked I/O page interface
2106                            to use symbolic base addresses and lengths
2107
2108 14      20-Oct-01       dec_dz.h, sim_tmxr_h, sim_tmxr.c: fixed bug in Telnet

2113                            for RSTS/E (found by Thord Nilson)
2114
2115 12      15-Oct-01       pdp11_defs.h, pdp11_cpu.c, pdp11_tc.c, pdp11_ts.c,
2116                            pdp11_rp.c: added operations logging
2117
2118 11      8-Oct-01        scp.c: added sim_rev.h include and version print
2119
2120                         pdp11_cpu.c: fixed bug in interrupt acknowledge,
2121                            multiple outstanding interrupts caused the lowest
2122                            rather than the highest to be acknowledged
2123
2124 10      7-Oct-01        pdp11_stddev.c: added monitor bits (CSR<7>) for full
2125                            KW11L compatibility, needed for RSTS/E autoconfiguration
2126
2127 9       6-Oct-01        pdp11_rp.c, pdp10_rp.c, pdp10_tu.c: rewrote interrupt
2128                            logic from RH11/RH70 schematics, to mimic hardware quirks

2131                            detect was being cleared on next modem poll
2132
2133 8       4-Oct-01        pdp11_rp.c, pdp10_rp.c, pdp10_tu.c: undid edit of
2134                            28-Sep-01; real problem was level-sensitive nature of
2135                            CS1_SC, but CS1_SC can only trigger an interrupt if
2136                            DONE is set
2137
2138 7       2-Oct-01        pdp11_rp.c, pdp10_rp.c: CS1_SC is evaluated as a level-
2139                            sensitive, rather than an edge-sensitive, input to
2140                            interrupt request
2141
2142 6       30-Sep-01       pdp11_rp.c, pdp10_rp.c: separated out CS1<5:0> to per-
2143                            drive registers
2144
2145                         pdp10_tu.c: based on above, cleaned up handling of
2146                            non-existent formatters, fixed non-data transfer
2147                            commands clearing DONE
2148
2149 5       28-Sep-01       pdp11_rp.c, pdp10_rp.c, pdp10_tu.c: controller should
2150                            interrupt if ATA or SC sets when IE is set, was
2151                            interrupting only if DON = 1 as well
2152
2153 4       27-Sep-01       pdp11_ts.c:
2154                         - NXM errors should return TC4 or TC5; were returning TC3
2155                         - extended features is part of XS2; was returned in XS3
2156                         - extended characteristics (fifth) word needed for RSTS/E
2157
2158                         pdp11_tc.c: stop, stop all do cause an interrupt
2159
2160                         dec_dz.h: scanner should find a ready output line, even
2161                            if there are no connections; needed for RSTS/E autoconfigure
2162
2163                         scp.c:
2164                         - added routine sim_qcount for 1130
2165                         - added "simulator exit" detach routine for 1130
2166
2167                         sim_defs.h: added header for sim_qcount
2168
2169 3       20-Sep-01       pdp11_ts.c: boot code binary was incorrect
2170
2171 2       19-Sep-01       pdp18b_cpu.c: EAE should interpret initial count of 00
2172                            as 100
2173
2174                         scp.c: modified Macintosh support
2175

2177
2178                         pdp18b_tt1.c: modified to use sim_tmxr library
2179
2180                         nova_tt1.c: modified to use sim_tmxr library
