# Change Log For V2.7

Changes since initial release:

15 | 23-Oct-2001 | Fixed bug in PDP-10 TU, PDP-10 RP, PDP-11 RP error interrupt handling. Added symbols for IO page layout in PDP-10 (PDP-11 to follow).
14 | 20-Oct-2001 | Fixed bug in Telnet state handling in terminal multiplexor library (found by Thord Nilson). Removed tmxr_getchar, added tmxr_rqln and tmxr_tqln in terminal multiplexor library.
13 | 18-Oct-2001 | Added stub MTRDL register to PDP-11 TM for RSTS/E tape changing timeout (found by Thord Nilson)
12 | 15-Oct-2001 | Added operations logging to PDP-11 (interrupts, RP, TS, TC).
11 | 8-Oct-2001 | Added patch level to simulator revision printout, SHOW VERSION command. Fixed bug in PDP-11 interrupt acknowledge: if multiple interrupts outstanding, lowest priority interrupt was acknowledged and higher priority interrupts were lost.
10 | 7-Oct-2001 | Upgraded PDP-11 clock to full KW11-L for RSTS/E autoconfigure.
9 | 6-Oct-2001 | Fixed bug in PDP-11, PDP-10 DZ11 carrier detect logic. Rewrote interrupt logic in PDP-11 RP, PDP-10 RP, PDP-10 TU to mimic exactly the interrupt logic in the RH11/RH70.
8 | 4-Oct-2001 | Removed edit of 28-Sep-2001 to PDP-11 RP, PDP-10 RP, PDP-10 TU, ATA/SC interrupt is blocked if DONE = 0.
7 | 2-Oct-2001 | Fixed bug in PDP-11, PDP-10 RP for lost interrupt in multi-drive operation.
6 | 30-Sep-2001 | Revised PDP-11 RP, PDP-10 RP to separate out CS1<5:0> on a per drive basis, to fix bugs in multi-drive simultaneous operation. Revised PDP-10 TU based on above, for proper handling of non-existent formatter errors.
5 | 28-Sep-2001 | Fixed bug in PDP-11 RP, PDP-10 RP, PDP-10 TU, ATA/SC should cause an interrupt regardless of state of DONE. Fixed typo in SCP examination/modification routines.
4 | 27-Sep-2001 | Fixed bugs in TS11 extended status returns and NXM termination codes; added extended characteristics processing. Fixed timing bug in TC11 stop, stop all functions. Fixed bug in DZ11 handling of receive done while disconnected. New facilities in SCP: sim_qcount and special DETACH ALL processing for simulator exit
3 | 20-Sep-2001 | Fixed bug in TS11 boot routine
2 | 19-Sep-2001 | Fixed bugs in 18b PDP EAE, PDP-7 LPT, typos Additional changes to Macintosh support
1 | 18-Sep-2001 | Changed PDP-8, Nova, 18b PDP extra terminals to use Telnet conneections, removed previous multiconsole support Changed calling sequence in sim_tmxr library Fixed bug in PDP-8 reset routine Added PDP-8 TSS/8 character formatting Added DZ11 autodisconnect switch Added Macintosh sockets library support
