Dear All,
I found several pdp-11 tape image files on the net which have ".tap"
suffix.
It isn't well known simh/e11/tap/tpc tape images.
Please help to identify which format they have.
How such file can be converted to simh .tap or .tpc or how it can be
used/mounted?
Below is the beginning of hexdump of one of these files named "F77.TAP":
[...]
Where did you find them? They look totally broken. I can't see any reasonable format in them at all. The first 512 bytes might be some kind of meta-information, but it's really weird.
Get some proper images instead, as from trailing-egde.

Hi,
I have built another little simulated machine:
Name: BITXOX
Address: 7.60
This one simulates a small VAX 11/730 running VMS 5.5. This machine has RSX11/VMS running and the GUEST account has MCR as default CLI. It's a little weird thing I have set up just as a curiosity. If someone pays a visit, please consider it is SLOW, with just 4M of RAM (several processes are swapped out just after startup), and sharing its host (a Rasp-pi) with several other virtual machines...

That's a parameter override file; it won't be in there unless someone

I have no idea. You guys have dug up this info....
Most Solaris folk aren't really accustomed to just rebooting their
machines.
So I guess I fit in? I don't even like rebooting NT 4. ;)
I suggest that you make the change to /etc/system now so you don't forget when you go to shutdown to install the NICs or you'll end up with multiple reboots at that time....
Then again, if your system has trouble rebooting after installing the NICs you won't know if it has to do with the newly added hardware or the change to the OS configuration file .
I'll let Brian be the guinea pig then. ;)
I like to test one change at a time.

Speaking of SIMH, anyone try the Alpha emulator in the betas yet?
Is it any good?
Just downloaded the beta sources but can't find a makefile or any docs, anyone got pointers?

Hello!
Actually most NT boxes don't need to be rebooted unless the user is
stuffing in software.
Oh and Dave? That Solaris box you have has been very helpful, for the
crowd of Cybermen who need a fast machine for their Cyberleader.
Fly? Hmmm. Be careful of your riding companions there's a crowd of
furry individual who need a fast flight someplace.....

First of all, Cory...have you tried using Sun's compiler? It kicks the snot out
of GCC for SPARC code generation. I did give you a copy.
I would suggest that this would be a good idea.
I have an old SparcStation which I fire up once every few years to test simh on a Big Endian platform. It has a Linux disk and a Solaris disk (I don't recall the version). I do not have a sun C compiler. The last time I fired it up (more than a year ago) the basic testing worked out fine but I noticed that some things were so slow it was practically unusable. I isolated some slow behavior down to an operation which walked across a 64MB chunk of VAX memory one byte at a time. The 64MB array is stored in a single malloc'ed area. This walk across the 64MB took some 20 seconds, while the same operation on my Windows desktop takes far less than any time I could measure on my watch. My theory was that it was spending all of its time in the alignment trap handler, but I didn't have enough knowledge to dig into the details.
The test case is demonstrated by the following commands:
$ BIN/vax
MicroVAX 3900 simulator V4.0-0 Beta
sim> set cpu 64m
sim> save somefile
The save operation writes the current simulator state to a file.
It sounds to me like you need a fast SPARC, or access to one.
I can give you an account on dev.neurotica.com, which is an
UltraSPARC-T1-based machine running Solaris 10 with Sun's C compiler
installed. Several people are using it for free software projects;
that's its purpose in life.
Let me know if you're interested.
