Bob's emulator is quite good, but a drawback is that it doesn't
have MSCP emulation or Ethernet emulation.

E11 (Ersatz-11) has both. I believe that Viking does as well. I
don't know about Charon...

Me? 10 Support? No...

I'm simply working on trying to get my KS10 operational, while working
off and on on a pdp-10 emulator, using Bob's package as a base. I
have been working toward a KA10 emulator with conditionals (where I
understand things enough) to do the right thing for a pdp-6 or a
KI, and for those instructions I have done, I'm getting almost
600k emulated instructions per second (eips?). But I don't have
the PI system working at all, and there are some issues about
instruction processing I don't have down yet...

Daniel Seagraves is working on a KL emulator, and actually has
some code running, it appears (at least he has tried to boot
ITS and it has done a little of the boot process).

There are some other efforts around the net to produce various
-10 emulations...

I'm also in the process of getting all the software I do have for
the 10, currently on tapes, off to other storage with the help
of Tim Shoppa (actually, I'm just supplying him with tapes, and
he's doing the work... :-)

Most recent mail from him indicates we appear to have almost a
complete 7.03 distribution, parts of the 7.03A patchs and working
on a 7.04 distribution.

But as for 'supporting' this stuff... I was an okay -10 programmer
in college... I mostly did -11 stuff. I'll never be anywhere near
the level of the -10 gurus who wrote this code... so I would not
presume to 'support' it.

Isn't XKL doing -10 support?
