Below is my previous posting on this thread.  Based on email repyies I got,
it appears I wasn't clear just what I was trying to say.

I was not proposing using the combo drive as an HD drive on an 3B1 - though if
some one can come up with a reasonable and inexpensive way to do this, I'd
seriously consider buying their kit.

I'm mearly investigating (at least as a "thought experiment") the possablity
of using the combo drive as 720K 3.5" and 360K 5.25" pair of drives (admittedly
with manual selection between the 2) in a signal half-height space.

If it is possible to use an HD floppy drive on a DD controller *AS* a DD drive,
then, barring any special actions involved in swithing between the 2 drives that
make up the combo drive, one should be able to use the combo drive as a pair
of DD drives on the 3B1.

Well, almost true but not quite.  The WD2797 floppy controller chip
itself is perfectly capable of driving a quad density floppy, you just
need to supply a different clock rate.  If you are really creative at
hardware hacking you could externalize the clock rate selection to the
WD2797 chip and be able to have your choice of any floppy drive you
wanted.

If you want to see something bizarre in relation to the floppy drive,
you want to see my machine with *three* floppy drives attached to it!
I've got the standard 5.25 40 track drive, a 3.5 80 track 720K drive,
and a 5.25 80 track 720K drive, with a three way rotor switch on the
drive select line.

Does anyone have or know an ftp site to find the program "expect"
or the "Tcl" library already ported to the 3b1 (so I don't have
to do it.)  I've heard interesting things about "expect" and I'd
like to try it out, and I understand that "expect" uses "Tcl".

No, not as 360K--but YES as 720K.  Yes, 720K 5.25.  You may have to install a
jumper or solder a jumper to permanently change the spindle speed.  Or, pin 2
of the interface can be grounded (I believe) to cause the drive to permanently
go into low-density mode.

Unfortunately, I cannot answer these questions, as I don't have a combo drive
(although they sound intriguing)....

Try the Korn shell, ksh (available in the osu-cis archives for
the 3b1). ksh has, as a standard feature, the ability to perform
command line editing using either vi or (ugh) emacs (for those
who like lots of extra keystrokes) commands.  In vi mode,
pressing the escape key followed by 'k' displays the last
command entered, which can be edited with most of the usual vi
commands. Pressing 'k' again shows the 2nd last command, etc.
One can also search for a substring using the vi '/' function.
You can find a man page for ksh easily, e.g. it's in the SVR4
User's Reference Manual (Unix Press, ISBN 0-13-947037-9). There
is also a book entitled "The Kornshell Command and Programming
Language" by Morris I. Bolsky and David G. Korn, published by
Prentice Hall, ISBN 0-13-516972-0.

A version of ksh may have been shipped with your 3b1. However,
the version in the STORE subdirectory on osu-cis is more recent,
and can safely be linked to /bin/sh. If you do the latter, you
will not have to make any changes to /etc/passwd to use ksh as
your login shell (assuming the shell field in /etc/passwd is
blank). On the other hand, if you put "/bin/ksh" (or anything
else) in the shell field of /etc/passwd, you may find that
/bin/su will refuse to give you a shell under some conditions.

BTW, something seems to be amiss with the news software on the
system you posted from: the headers lack domain names!

Subject: 610 terminal still not working w/ 7300
Date: Thu, 15 Oct 1992 18:57:06 GMT
Organization: University of Louisville

Ok, one last inquiry.
As suggested, I connected my att610 teletype terminal to the RS232 prot on my
7300 via a null modem cable.  It still doesn't work.  (I have also used the
terminfo database to "update" the terminfo file (although the 610 was already
there)).  I have 3 final questions. 

1.  Is it pins 2 & 3 that are swapped on a null modem cable.  I haven't had the
opportunity to go in search on one or one of those adapters, and don't know
anyone who has one to test.  I found the one I have at work and bowwored it.
2.  Does the terminal require moreor other pins than 2-8, 20, 22 on the cable.
If so, does anyone know which ones??
3.  When do a "ps -edaf" from the root account, there is a getty process
running, but its tty is listed as "?"  I used the install account of UA to
setup the 7300 for the terminal.  IS the getty looking in the right place
(tty000) if so why doesn't it say so.  If not what can I do to get it to look
there to see if I should go ahead and pay the $7.00 Radio shack charges for a
NULL modem adapter or if there is something else I need to do to get the
terminal to work.  

ANY help will be appreciated.  Please reply to one of the addresses below.

720KB drives are 360KB drives with 80 rather than 40 tracks.  In the 5.25
versions, anyway, you can turn a 720 into a 360 by double-stepping the
heads.  They use the same data rate, which is why 720 drives work on the
7300.  1.44 MB drives use a higher data rate, and more sectors per track -
I don't know how they read 720s

Currently, the project is at a standstill. Information for design work

Yes, in fact one of the guys who was on customer support for the unix-pc
kernel told me that a total rewrite of the phone polling code to make it
interrupt driven would save quite a bit of processing time.

In case you're wondering about the status of the kernel source code
availability, I finally got ahold of the USL lawyer last month, and we
sent a few faxes back and forth. She's forwarding them on to somebody who
(hopefully) can approve everything. I don't mean to get your hopes up... just
trying to report the facts.

I'll keep you posted...

I've found what appears to be a related bug in the STORE version
of ksh: if one uses the trap ksh builtin command (also valid for
/bin/sh) to cause some signals (e.g. interrupts) to be ignored
while reading startup files (e.g. /etc/profile), multiple use of
the trap command can cause the signal(s) in question to be
permanently ignored. For example, if /etc/profile looks
something like:
	
	trap "" 1 2 3 # ignore HUP INT QUIT
	# .
	# the trap statements are fist and last, with the 
	# ``useful'' work being done while signals are disabled
	# .
	trap 1 2 3 # restore default handling of HUP INT QUIT

and $HOME/.profile (and/or $HOME/.kshrc or equivalent) are
similarly structured, by the time the shell finishes reading the
startup files and presents a prompt, these signals are
permanently ignored, even though they should have been restored
to default behavior (and even though "trap" (no arguments) does
not report any signal handler for these signals).

If only ksh will be used, then one could put only the 
	trap "" 1 2 3
statement in /etc/profile, and only the
	trap 1 2 3
statement at the end of .kshrc, but if /bin/sh is also used, and
/bin/sh is not a link to the /bin/ksh, then the defualt
behavior for signal handling will never be restored (since
/bin/sh doesn't read .kshrc).  If the latter statement appears
at the end of (only) $HOME/.profile, then it will be OK for
/bin/sh, but interrupt characters (a DEL is commonly encountered
on a noisy (modem) line, which is why one would like it to be ignored
during processing of startup files (changing the interrupt
character doesn't help, since any character *might* result from
line noise)) will not be ignored during the processing of .kshrc.

Has anybody found a reasonable work-around for this problem (or
a patch to the binary executable, or a better binary version of
ksh)?

As I recall, I had the most trouble when selecting for any time interval
taht was not even seconds (i.e. timing with finer granularity than one
second).  In general, I found that rounding select timeouts up or down to
the whole second seemed to help a great deal.  I think that any large value
will cause trouble.

The exact problem that occurs is a timeout table overflow - obviously a bug
(er feature) of Wollongong's select implementation for the 3b1.  Presumably,
you could crank up the size of your timeout table (if you had spare memory
to burn that is...) to delay the panic's occurance.

> And, are there any

Oh lord, the list is too long!  Just don't expect anything really fancy and
you'll probably be OK...

Disclaimer: it's been a while since I pretty much gave up struggling with
TCP/IP on 3b1s.

It's user-configurable, but the default is the delete key. If you'd prefer it
to be control-C, you can type (or place in your .profile or wherever):
	stty intr ^C

For whatever it's worth and considering that I'm offering the statistic of
one, 

	I drilled holes in the side of the case so I could insert
	microwave thermometers over the power supply. One critical
	point measured was over the red coil at the front of the PS
	where the highest temp seems to be.

	After reversing TWO dc fans, the temp over the red coil jumped
	thirty (30) degrees F. That's where the case melts when the PS
	goes. 

	Consider: The red coil that gets so hot, is forward (toward the
	keyboard) from the slots/louvers/vents in the top of the case,
	thus it is NOT in line with the air flow from the slots when the
	fans blow OUT the back. That's bad enough, BUT, when the fans blow
	in, it's like trying to blow into a coke bottle. It's very unlikely
	that there is as much air circulated past that coil with the fans
	blowing in as when the fans blow out - apparently verified by the
	change in temp when the fans are reversed in MY machine.

	Suggested improvement for better cooling with the fans in either
