Was this is response to the thread a couple of months ago?
Paper tape is still available from several suppliers, though only a few
companies still actually make it. However, not all modern "oiled" tape
uses resin -- some manufacturers do still use oil, according to the
company in the UK who are getting me some (from Germany). Resin is an
effective barrier, but worse than useless as a lubricant.

That's probably 3.6x. Sadly, Frank da Cruz no longer keeps older
versions of Kermit online (something I regret, as periodically I need
to find yet another version for some newly-acquired machine, and also
because I dislike the bloat that happened between C-Kermit 5 and 6).
Luckily there are other places to find it.
Thanks to Tim Shoppa, several DECUS tapes are available which have
versions of Kermit-11. It's usually in account (directory) [356,040]
on the tapes which included it. Look for the file k11ins.rno (or
k11ins.doc, which is a flat ASCII file but most servers wrongly assign
a MIME type of application/msword to it, just because of the suffix)
for release notes. .rno is a RUNOFF file, the source for a document
processing system akin to (but much older than) troff.
3.51 (Spring 1986) runs under 7.2 but doesn't handle binary files
properly, and only builds under 8.0 or later. It's at

/decus/rsx86a/356040/
2.30 (June 1985) says:
"This is release 2.30 of Kermit-11. It requires RSTS version 7.2
or later, RSX11M v4.0 or later, or RSX11M Plus version 2.0 or
later, or RT11 version 4.0 or later, or P/OS version 2.0 or
PRO/RT11 version 5.1
Minimum system requirements to run Kermit:
RSTS v7.2 or later, with multiple private delimiters"

2.17 (August 1984) says
"This is release 2.17 of Kermit-11 for RSTS and RSX11M/M+. It
requires RSTS version 7.2 or later, RSX11M v4.0 or later, or
RSX11M Plus version 2.0 or later, or RT11 version 4.0 or later.
Minimum system requirements to assemble and link Kermit
RSTS v8.0 or later, with multiple private delimiters and RMS V2
Kermit-11 will run on RSX11M version 4.0 and RSTS/E version 7.2
as long as the task was built without using RMSRES. To be able
to build KERMIT on RSTS version 7.2 or RSX version 4.0 you will
have to get RMSLIB.OLB and MAC.TSK from RSX v4.1 or RSTS v8.0."

Most of these have pre-built binaries in the form of .hex files; these
are flat-ASCII hex representations of the binary, intended to be
stuffed over a serial line by a simple terminal emulator or whatever,
in case you don't already have Kermit or something similar to transfer
a binary.
There are also de-hexifier programs in various forms (BASIC, FORTRAN,
C, etc).
Most of those directories also include other verisons of Kermit (ie,
not for DEC OSs). I discovered that last URL I gave has C-Kermit 4C
:-)

I mentioned this before, but the subject line may not have caught the right
people's attention. I need access to an ASR TTY with the reader-run mod to
do some final testing on some cards I am developing for myself and the
group. If you have a pdp-8i or pdp-8L that's great, otherwise I can bring
my 8L. I am in the Portland (PDX) metro area (Beaverton, actually).
The cards have already been tested with a TTY which does not have the
reader-run feature, so it is that specific feature I still need to test.
Anyone out there who can help?
Thanks!

Newer paper tape is not oil impregated at all but has a barrier / lubricant made from resins. Tape is still available from The Trybus Company in Pittsburgh. (412 367-1880) They also carry Mylar tape which I prefer.
Quite often a customer will come to me with an old worn out executive tape and ask me to "do Something". I will generally read in the tape using a DSI reader that I have slowed down to 30 CPS and have narrowed the strobe width to 1/6 the charactor width. I will then use a FACIT 4070 to generate a new tape onto Green/Gold mylar. On executive tape using all 8 bits and no parity I use norton disk edit to make any manual repairs. This eliminates the need to splice fragile originals.

Last week I got the system unit and the tape drive mounted in the rack,
and yesterday, I managed to mount the Fujitsu Eagle. Now I'm trying to
figure out how to hook it all up...
I have been tinkering with it this morning, and finally, about a half
hour ago, I was able to see some activity. I found the information on
the serial board in a handbook, set the terminal for the proper baud
rate, etc, and connected it to channel 3 of the card. Powering it up
gives me the @ prompt. So far, the only things in the machine are the
CPU, the serial card, a 1mb memory board, and an Emulex tape
controller. Now that I have gotten it to do something, I'm totally
lost. I've never worked on a machine like this before. I don't even
know how to type in the boot program. I have a tape boot program here,
on a piece of paper, but I don't know how to type in the values. I've
tried all sorts of commands, all of which yield a ?. Typing P seems to
step the processor through something, as it prints 000002, and then
typing P again increments that value. G prints 177777, and the LED on
the tape controller lights briefly. Same thing if I toggle the boot
switch. I tried loading a tape into the drive and putting it online,
but I get no drive activity when I toggle the boot switch.
So, can anyone offer hints or suggestions as to what I should do next?
I'm lost...
Thanks!

Here is a page scan and the text from a 1978 PAiA catalog. The PVI appears
to be Don Lancaster's TVT-6.
http://www.swtpc.com/mholley/PAiA/TVT6_640.jpg
Michael Holley
www.swtpc.com/mholley
Don Lancaster's ingenious design provides software controllable options
including:
Scrolling
Over 2K on-screen characters with only 3MHz bandwidth
Full performance cursor
Variety of line/character formats including 16/32, 16/64 even 32/64
User selectable line lengths
You'll want to see the operational details on this first. The PVI-1K is not
the universal answer to every video display requirement. In applications
where its minor limitations present in?surmountable obstacles to a design,
more expensive techniques should be used. If you are in doubt, the PVI is
completely described in the July and August, 1977 issues of Popular
Electronics. Reprints of these articles are the instruction set for this kit
and are available separately for $2.00 postpaid refundable upon purchase of
the PVI kit.
Complete kit includes circuit board, all parts and instructions and is
available in either of two forms.
PVI-KM Ready to go with KIM's $34.95 wt. 1 lb.
PVI-MT For other processors
(requires PROM coding) $34.95 wt. 1 lb.

OfficeConnect hubs, switches, whatnots, are very small devices that
have an external wall-wart PSU and no fan, and are normally absolutely
silent.
