Oh, and there is the patch to enable the idle feature of KLH10 too!

That will be even more helpful!

Patching monitor sources, rebuilding monitor modules and then replacing them
into TOPS10.REL is a bit involved and now here is late evening, so remember me
tomorrow or in a couple of days. :)

For now I'll just write how to patch the monitor file because it's quickier.

First of all, add the following to your KLH10 initialization file:

	devdef idler 740 host

Then make a copy of your SYSTEM.EXE and work on the copy:

..R FILDDT

File: xxxxxx.EXE/P   <--- /p to enable patching

[Patching file DSKB:xxxxxx.EXE[1,2]]
[35118 symbols loaded from file]
[ACs copied from CRSHAC to 0-17]

<--- FILDDT prints nothing, but it's ready to accept commands

nulcod+1/   <--- type this and nothing more

nulcod+1/   SOJG W,P   <--- DDT will show you the contents of that location

nulcod+1/   SOJG W,P   CONO 740,1   <--- tell him to put this there instead and
                                                                        press enter to confirm

<--- if all goes well FILDDT prints nothing again (friendly, isn't it?)

^Z <--- to save and exit

Now try to boot with your patched monitor and see if does idle KLH10. This
monitor will work only if there is a device at address 740.


That didn't quite work as planned...

?Stopcode KNIKSP, type=INFO, on CPU0 at 15-May-113 18:43:58
[Continuing system]

It's idling...but by idling it's stopping completely. ;)
