[TUHS] 4.1cBSD Anyone?

[Benjamin Huntsman]

Hi all!
   Just curious, has anyone here managed to get 4.1cBSD (or any 4.1 for that matter) running under SIMH or any other hardware or software?
   How does one prepare a SIMH-format distribution tape from a collection of files?  I haven't found a whole lot of information on the subject, and I imagine it'd be fairly difficult to make a root dump without a pre-existing system...

Many thanks to all in advance!

There is a 4.0 floating around, that Nao got running... You can find
his notes here:

http://zazie.tom-yam.or.jp/starunix/

As for making tape images, it's easy if you have access to a working
perl interpeter..(I use SFU/SUA under Windows...)

I have a few examples here:

http://gunkies.org/wiki/Mkdisttap.pl


If you have access to file dumps of the tapes, it would *PROBABLY* be
trivial to get them into something simh understands and get something
booting...  If the asm for the tape load doesn't work, I've had great
luck manually running the bootra program, and pointing it to a copy of
the rootdump..

Where is your source for 4.1c?  Perhaps it's similar enough to 4.0 or
4.2 that it could be setup with either......

Yep.  I found that one, and it actually works.  It was a breeze to set up.

I'm using mktape.c to make tape images, but it doesn't compile correctly on my copy of Windows, so I'm using my Mac to make images, then transfer them back.  But, that's beside the point.
The hard part is finding the standalone utilities like mkfs, restor, etc, and creating a root dump without a pre-existing system.

I got the 4.1c archives from an acquaintance with the CSRG CD-ROMS.  Unfortunately, they're just loose files in a tar archive.  I'll probably try manually compiling the 4.1 stand-alone bits under 4.0, and see if I can create a dump by extracting the tar file onto an empty partition and dumping that...

But, can someone tell me, what program gives that '=' prompt, and how do you get utilities like mkfs, restor, etc onto the tape so that you can load them?  Do you just dump them as separate records to the tape using dd?

Sorry for the newbie-rific questions.  Gotta learn somehow...

Thanks in advance!

the first file on the tape is a bootstrap that will load the stand-alone utilities
the stand-alone utilites are files blocked 512 bytes/block after that. the files themselves
are in the sa directory in the distribution.

I'll try to find my actual tape images of the distribs after lunch. This should be about the
same layout as in 2.9.

I just added a second image that appears to have all of the records of the
first file blocked at 512 bytes.

I would suggest anyone trying to get this running have the CSRG CD #1 handy.
You will need to read setup.t in the doc/vmunix docs since it requires a keyed in
bootstrap. Most likely, you need to put boot.file (see below) starting at
location 0, and start it at 0.

Note in the docs that you will need a MASSBUS disk and tape configured.

Key in at location 50000 and execute the following boot program:
You may enter in lower-case, the LSI-11 will echo in upper-case.

Terminate each line you type by carriage return or line-feed.

The tape should move and the CPU should halt at location 5002A.
If it doesn't, you probably have entered the program
incorrectly.
Start over and check your typing.


Start the CPU with

The contents of the first file on the tape appears to be boot.file
In a quick inspection, it seems to match the contents of the first
file on the tape.
