====== TYMCOM-X Project Status ======

===== Status =====

  * Q: Why did the first attempts fail?  A: ''14035E.SAV'' and others expected a KMC11 co-processor and custom microcode for ''UUILDB'' and ''UUIDPb''; two op-codes that read and wrote in KMC11 format.
  * Q: What was the workaround? A: Redefine ''IFKMC'' and ''IFNKMC'' and re-assemble from sources.
  * Q: What failed then?  A: ''CLOCK1.MAC'' was corrupted, and jury-rigged to work with an older version.
  * Q: Did that work? A: No level 7 interrupts, no incrementing of UPTIME or reading the ''IRING''.
  * Q: How was that fixed? A: With help from the simh github team, found a part of ONCE that was using a fullword quantity before its page had been mapped; it set the interval timer to zero, which acted differently on NetBSD than on the others.
  * Q: Working now?  A: No, the login got immediately zapped.  The code to change from super-SHUT to plain SHUT was inside an ''IFKMC'' conditional.  Fixed.
  * Q: What about DZ11 support? A: When ''DZKON'' is enabled, login at the console is done by simply hitting RETURN.  The DZ11 lines respond to telnet by echoing characters, but no logins.
  * Q: Now what?  A: Can get logged in, but attempts to ''.RUN MTA:TITO.SAV'' are failing.  The same tape can be read by TOPS-10 using the ''COPY'' command, but not by the ''RUN'' command.
  * Q: Run ''TITO'' from disk? A: Modified ''ONCDSK'' to allocate and create empty ''SYS:TITO00.SAV''. Used TOPS10 to put ''TITO'' there via FILDDT. 
  * Q: Did that work? A: No ''TITO'' appeared to be hung, but it was looking for position 1 which was not on the  ''TITO'' tape.  Giving it the argument ''301-e'' worked, was able to restore from both savesets in less than one minute each.
  * Q: What about BOOTS? A: ''gfd ks2020'' and ''run ksfefs.sav'', but that overwrote the wrong pages.
  * Q: Why? A: ''DSKCHR'' was returning a pointer to the RIB of ''FEFILE.SYS'' instead of length and starting page number.
  * Q: Workaround? A: Modify ''REFSTR'' to return hard-coded pointer to the FEFILE.SYS data pages.
  * Q: **Current status**?  A: Can load TYMCOM-X from disk and login on the console.  DSKCLN does not run automatically, otherwise all is well (for logins on the console only).  **X14** is a two-pack system, **X17** is a three-pack system.  **X95** is a single-pack system for debugging DZ11 logins.

===== Other systems tested =====

Both the version for Windows (run via CMD.EXE) and Cygwin (compiled on Windows 7) produce the same results as the Linux and FreeBSD/NetBSD.

==== Sharing files ====

=== Using ''rsync'' to NetBSD test system ===

  Linux% cd; rsync -av pdp10/simh-ks/ tty:pdp10/sim-ks/

=== Using Google Drive to share with simh developers ===

Make a compressed ''tar'' file of everything in the simh-ks directory.  Copy the ''txz'' file from Linux to Google Drive.

When creating a tar file, note that "j" (bzip2) produces much better compression than "z" for *.dsk files.
(Using capital "J" compresses better, but is not standard on MacOS.)

  Linux% tar cvfj /b/share/data/tymcom-x.tbz simh-ks/*

Place in a private directory on Google Drive, right-click to get a URL to share.

To share a working system, enter one of the following commands:

  Linux% tar cvfj /b/share/data/3-pack.tbz simh-ks/pdp10* simh-ks/x17* simh-ks/readme.*
  Linux% tar cvfj /b/share/data/2-pack.tbz simh-ks/pdp10* simh-ks/x14* simh-ks/readme.*
  Linux% tar cvfj /b/share/data/1-pack.tbz simh-ks/pdp10* simh-ks/x95* simh-ks/dz11* simh-ks/newmon.*
