As for the matter at hand in this pull request, I am myself a big fan of reusing other people's code. I guess that's some kind of vote in favour...

Original bug report: ``` KLH10> go Starting KN10 at loc 0144550... Salvager 260 Program received signal SIGSEGV, Segmentation fault. 0x00000000004243da in rp_clear (rp=rp@entry=0x649760 ) at ../../src/dvrpxx.c:1190 1190 rp->rp_sdprp->dprp_err = 0;...

When SIMH boots from a tape (or disk), it loads "boot ROM" into memory at location 377000, and jumps to that. Does this seem like something we could copy to...

@brouhaha I'm primarily interested in booting on a KS10, because the version of ITS we have today ran on that machine. The 8080 front end has an `MT` command which...

@Rhialto I did try the `klt20/mtboot.sav` file, but it doesn't work with the ITS configuration. I believe the IO instructions are incompatible with the ITS MUUOs. I will try extracting...

It may be worst on my fastest machine. I rebuilt KLH10 with those changed options, but I don't think it made any difference. Using NSALV to restore files works very...

Looking at the TM03 tape controller right before the failure. This is from KLH10 with `debug=1` passed to the mta0 devdef. ``` Tape #1 .;DSKDMP RP06 [tm03_rdreg: r1/ 14400] [tm03_wrreg:...

So apparently, the `TM_WCF` and `TM_RDF` case in `tm_cmdxct` turns off the ready bit, `TM_SRDY`. Now, if I just comment out that line, everything works fine! Not saying that is...

Some more testing with an unmodified KLH10: - On my fast home machine, it fails consistently at the first tape file. - In a Linux running in VirtualBox, it sometime...

`-DKLH10_DEV_DPTM03=0` works fine, so I'm happy to use that as a workaround. I'm just not sure how to pass it to the build system. - I tried `configure CPPFLAGS=-DKLH10_DEV_DPTM03=0`, but...
