NOTE:
Similar to modern unix but a number of noticable differences. Many of
the command flags are not present. File names limited to 14 characters.
The standard tar restore the file ownership so if it restores the top directory
with owner you can't write to it can't extract the files. Use gnutar.

Installed using install account and floppies

Created stuff in /usr/local


cd /dev
# mknod window1 c 7 0
# mknod window2 c 7 0
# mknod window3 c 7 0

This allows switching sessions with ctrl suspd and rsume

Added getty for window 1,2,3 and /dev/tty000 in /etc/inittab. tty000 baud
rate 9600. The serial port supports 19200 but getty doesn't.


mread seems to make files upper case. mklower.sh can convert filenames to
lower case

piping to tar doesn't work properly with sh. Works ok with ksh.

kermit (on PC)
set line /dev/ttyUSB2
set speed 9600
set send packet-length 2000
set file names literal
SET CARRIER-WATCH OFF
connect
kermit (on 3b1) Demo account has .mykermrc with somewhat differnt options
   that also work ok.
set window 3
set receive packet-length 2000
set file names literal
set file type binary
receive
control-/ c
send
Kermit seems to loose character on the built in rear serial port above 9600
baud so has to resend packets.

mtf - mount unix floppy
mdir, mread, mwrite - Access dos disks. Also built in msdos command.
/dev/fp021 is floppy first partition, /dev/fp020 is full disk


nethack etc set to group writable. Normally was setuid etc.

to install software put in /usr/spool/uucppublic. Must be named name.1+IN etc
Note deleted after install.


Put in /usr/local gzip (1.2.3) from unixpc.taronga.com/ftp.uu.net/systems/att7300/csvax/


emacs
meta M- is escape, C- is control
To recompile all new/modified list macros
M-x emacs-lisp-mode
type

C-x C-e


To use 3b1 filesystem code
Use starling 3.19.8 with code built for it.
./s4export -i file.ext -o file.fs
Running fsck fixes free space with mount below.
./s4fsck file.fs
mount -o ro -t sysv -o loop file mountdir


Discuss the Store! and easy install/uninstall

setup demo with kermit default and some shell configuration.
enter ksh vi history mode with escape

installed gnutar to get around extracting files with owner that doesn't
   match system


To look at install file
UNIXPC
cpio -icBt < file+IN
Linux
cpio -it < file+IN

Installed gcc 1.42, bash 1.12, played with include files
GCC 2.5.8 available but too large for the 1M memory I was making this iamge on

Manually added lisp emacs doctor,hanoi and needed for support backquote

Make bwbasic. Configure wouldn't run with the old shell so Makefile is from
build on Linux Various -D flags set to make build work and local
copy of sys/types.h made to remove conflicting typedef.

Couldn't build bwb_fnc.c, bwd_cmd.c with opt
bwb_fnc.c: In function fnc_intrinsic:
bwb_fnc.c:4167: Virtual memory exhausted.

for printing man pages and nroff files on modern printers use groff to
generate postscript and ps2pdf if needed. To increase font size and indent
Use -man for man pages.
.ps +1
.in +.5i

ctrl-j for remote sessions to simulate enter key for windows.


Issues
When kermit sends a file to PC the PC ends before kermit thinks the last
packet is sent to it keeps sending packets. Need to wait for timeout or
quit kermit and restart and log back in.
