Hi,
I'm finding inconsistencies between the HP-67 & HP-97.
I'm looking for an HP-97 Manual and saw a note from Joe that stated Mike Haas
found one. Is it for sale?

I'm beginning to wonder if it's time I upgraded my home network. The
NICs on most of the machines are 100BaseT, with the odd old machine
sporting a 10BaseT. But it's the hubs I wonder about--two old
National Semi 6-port Datamover 10BaseT units coupled together with a
10Base2 (coax) link. It's that coax that I dread replacing--it goes
between floors and snaking it through the walls was a real chore.
My DSL speed is 1.6Mbps, so I'm thinking that there's little reason
to upgrade the setup. Am I thinking correctly or am I likely to see
an improvement in internet access speed if I upgrade?
Cheers,
Chuck

This reminds me of an interesting phenomenon we discovered in 1974...
the high school had an ASR-33 connected via a leased data line
(telephone with acoustic coupler) to a PDP-8/E running TSS/8 at Clemson
University, 60 miles away.
I can't remember exactly what the code was any more, but it was a very
simple patch -we would deposit a mere three words at location 307
(octal) and execute it (ST 307), and the terminal would log on another
job. So you'd have two accounts open simultaneously on the same TTY!
And if you logged off one account the other would still be open so you
couldn't log off both... they'd have to reboot the system to kill it.
Any TSS/8 gurus know how we might have done this?
We also "inadvertently" deleted the contents of one of the library
DECtapes once... there was a "ZAP" command that zeroed out the tape, so
naturally we would type in "R ZAP" frequently, and get the expected
"WRITE LOCKED" error. One day, though, it actually did it =:^0 Guess
the operator forgot to flip the write lock switch!

Remeber- two types of radiation: particle (Alpha, Beta, neutrons,
protons) and electromagnetic (gamma, X-ray, radio, light, etc). The
particles can make things radioactive, the electromagnetic radiation
cannot.
Oh my, what am I going to do with these MDI SCSI CD boxes? I have 3 or 4 of
them, each one containing seven CD-ROM drives, a power supply, and some
kind of logical unit controller, so all 7 drives appear a LUNs under one
SCSI address.
The drives are Toshiba XM-5301B, a 4x tray-type (doesn't need caddies) that
works sideways or in the more usual orientation.
Specs here, from http://www.netcomdirect.com/tosxm4xfonco.html
CD-ROM Mode 1 -data discs
CD-ROM Mode 2 - data discs
CD-DA audio discs
CD-DA/ROM - Mixed mode/combined
CD-ROM XA and Photo CD (Single and Multisession)
CD-Bridge (White book, Video CD)
CD-I, CD-I ready
The cabinets are 17" but with ears for std rack mount, 7 inches high, depth
behind the rack 20 inches.
Anyone (local) want some? Anyone got any ideas what to DO with them?

Yes, I'm replying to my own message!
I did a quick search on google and came up
with 300 links (searching for "Exatron Stringy
Floppy").
Unfortunately, I was unable to confirm what
the ESF's were made of. The sources also
state different increase read/write rates
over cassette drives. Here are some of the
better links (including pics of the unit and ESF):

Yes, you are quite right Chuck.
The ESF (Exatron Stringy Floppy) drive,
advertised on the back of most of my issues
of 80 Microcomputing, didn't last long despite
the heavy advertising.
As I understand it, the folks at Exatron hoped
it would become the new standard for storing
data. Unfortunately the 3.5" floppy disk (or
one of similar size) was invented around the
same time and, obviously, became the new
standard.
The ESF was about x10 faster than a cassette
and the floppy was much more than that
(atleast x20?).
As I understand it the ESF's broke down after
a year or so. The thin layer of stuff (i forget
now, some ferrous material) which was coated
onto the erm... mylar (?) started flaking off
rendering the ESF's useless.
I'm sure I read an article on ESF's about 6
months ago... hense why I know a bit about
them. It may have been in an issue of 80
Microcomputing.
