@Import klh10-2.0h as emulators/klh10.

PDP-10 KL10B model emulator. KL10B model supports extended addressing.
Tap networking support is from http://www.falu.nl/~rhialto/klh-diffs2 .

This package is potentially built on i386, amd64, arm, alpha, sparc,
and powerpc platforms. But this package supports i386 and amd64 only now,
and only amd64 build is tested, due to lack of my test environments.

@@@@ -1116,6 +1126,36 @@@@ mistakenly "fixed" to disallow it (FreeB
 other host before telnetting back into the KN10.  A better solution
 would be to fix those OSes that are open-source, and push to have
 these fixes incorporated in the standard releases.
+	For NetBSD (it may work on FreeBSD too) there exists a better
+solution. A special configuration is created with a virtual ethernet
+segment that has its host-side in the form of the interface tap0 (as in
+the example below). The tap0 interface is bridged to the real network
+interface. The NI20 is at the "other end" of the virtual ethernet.
+(This differs from the other connectivity methods where the named
+interface is the one that is basically used as the NI20). The NI20 is
+therefore a dedicated interface:
+
+	devdef ni0 564 ni20 ipaddr=10.0.0.51 ifc=tap0 dedic=true
+
+If the named tap interface already exists, no further changes to its
+configuration are made. You can use this for alternative connectivity,
+such as routed on the 10.0.1.0/24 subnet (instead of bridged):
+
+	# To the shell, suppose your real network is 10.0.0.0/24,
+	# create a 10.0.1.0/24 network for KLH:
+	ifconfig tap0 create inet 10.0.1.1 netmask 255.255.255.0 up
+	; in .ini file:
+	devdef ni0 564 ni20 ipaddr=10.0.1.51 ifc=tap0 dedic=true
+	! in SYSTEM:INTERNET.ADDRESS on TOPS-20 v7.0
+	IPNI#0,10 0 1 51,PACKET-SIZE:1500,DEFAULT,PREFERRED
+	! in SYSTEM:INTERNET.ADDRESS on TOPS-20 v7.1
+	IPNI#0,10.0.1.51,PACKET-SIZE:1500,LOGICAL-HOST-MASK:255.255.255.0,DEFAULT,PREFERRED
+	! in SYSTEM:INTERNET.GATEWAYS on TOPS-20 v7.x
+	PRIME 10.0.1.1
+
+(If TOPS-20 v7.0 can't do subnetting it might be better to use a
+192.168.2.0/24 network)
