I have a bunch of old data tapes that my father (deceased) wrote on his TI
733 ASR terminal. Any idea how I might go about accessing data on the tapes
or transferring to more modern media?

Hello,
I'm a student interested in retrocomputing. That's why I started
programming PDP-8 assembly a few days ago (Debian basically delivers all
you need to do that, i.e. simh and palbart). One problem I have is the
documentation. All that I found is either only a reference for the
PDP-8 instructions or the documentation of PAL III assembler. The third
thing I had as reference was the source code of OS/278. All in all, very
incomplete. Now I learned about the "Introduction to Programming" by
DEC, written for and about the PDP-8. Unfortunately I was unable to find
a copy of it on the internet. Now I ask whether anybody of you has a
copy of it (machine-readable preferred). In Austria, DEC hardware
doesn't seem to have been very popular at that time, so documentation
isn't easily available, either (it's even quite hard to get VAXen,
fortunately I did).
Thanks in advance,
Andreas Krennmair

I guess I should give a little background for the folks who haven't heard
>from me privately lately.
Just a few weeks ago or so (has it been that long already?), I ended up
rescuing nearly an entire ham shack/photo/woodworking shop from a 40cu
yard dumpster. A friend of mine who lived around the corner died a few
years ago, and even after picking up tons of stuff from his family, and
after numerous attempts to arrange pickup of the remaining stuff, I found
out some of his family dumped the entire shop into a huge dumpster (or
skip for you folks on the other side of the pond). Thankfully, I found out
about it *before* the dumpster was to be picked up.
I spent a total of around 22+ hours (with permission from the folks who
filled the dumpster) over the course of two nights with the help of a work
light pulling out everything I could salvage. There were a few things
missing (someone else got there first), and 1000s (I'd guess that number
anyway) of magazines and some books were ruined due to rain before I found
out about the dumpster. Magazines dating from the 1940s to the 1970s were
mostly ruined beyond salvage. These included titles such as Popular
Science, Popular Mechanics, Mechanix, and Popular Electronics. It also
included 3-4 different photo oriented publications with dates from early
1970s to the 1980s.
Ironically, they also accidentally trashed 1000s and 1000s of photos,
slides, negatives (both plastic and glass plate), and home movies. I've
been returning those items as I sort them from the rest, since they did
not mean to trash them. I still need advice on unsticking/cleaning the
home movie films, since none were in water tight containers. Most are
small reels in 3"x3"x3/4" cardboard boxes. I did explain to the family how
to separate/clean prints, and I think about 99% of those were successfully
salvaged.
I am currently trying to figure out how to clean/salvage books that were
exposed to the water, and since the texts are irreplaceable, I'm hesitant
in what I try. Many books have a very fine powder-like mold on their
covers, while the pages are ok. Some books have small amounts of mold
growing on the edges of the pages.
I also rescued a huge vinyl 33 1/3 record collection that needs to be
cleaned up somehow. They were added to the dumpster (by mistake I was
told) after the initial dive, and were subsequently exposed to yet more
rain (Houston really sucks sometimes). I'm very worried about cleaning any
mold from the album covers, but I imagine most of the vinyl is currently
ok. Some of the records may have been broken when they were dumped into
the dumpster, but I expect to find most intact. I imagine these may be the
most time sensitive of all the rescued materials.
I am also trying to figure out how to clean minor mold from and separate
QSL cards that are stuck together. The cards date from the 1950s, but
thankfully most were not exposed to water. I also have 100s of HARC
publications that need to be salvaged. Some are in very good condition,
while some have a significant mold growth on them.
I should also add that I am keeping all the items stacked (and piled) in
my (unfinished) computer building (nowhere else to put them at present),
and have been keeping the lights on 24/7 to help inhibit the growth of
mold.
Also, if there is anyone located in Houston that feels like lending a hand
in sorting/cleaning up stuff, please contact me. It is abit overwhelming
for me to try to deal with ~50-60 years worth of items.

Good morning, Al!
I apologize for the delay in responding to this. I work 8 am to 3 pm, EST,
Mon-Fri, so I had already left yesterday when you sent this.
We are located in Erie, PA. I have some links with photos of the items. We
are asking $999.00 plus shipping for everything or $950.00 plus shipping for
the computer system and software (no printer).
Just saw you posting about conquest. This was an old favorite of mine. I
Googled it this morning because an old college chum and I were reminiscing
last night. You might want to check out www.radscan.com/conquest.html
Looks like ConQuest was ported to linux, and this site has a telnet service
where you can go play (just like the good old days). Not quite the same as
a VT100 hooked to a VAX750, but, fills the bill ;-)
Take Care!

If any of you list members ( that are also eBay buyers, as many of you are
) feel
as we do, that computer components should be shipped in some type of antistatic
packaging, you might wish to avoid purchases from ...
eBay seller ... davidth
dba ... Tec Instruments Inc
We purchased a computer card from them that they did not place in an antistatic
bag. They just wrapped it in clear bubble wrap, which is not an antistatic
material.
As most, if not all, of you well know, the pink bubble wrap is the
antistatic variety.
We just purchased a roll ourselves that cost us less than eight cents per
square
foot. One square foot ( eight pennies worth ) would have been sufficient to
have
done a decent job, but that was not done.
They also did not realize we had paid them for the part virtually
immediately after
the auction was over ( IIRC we purchased with the Buy It Now feature ) and
SIX WEEKS+ LATER when we still hadn't received it, we had to call and inquire
as to it's whereabouts.
We felt that a job done that poorly did not deserve a positive comment, so we
gave them a neutral comment calling it like it was. This seller sees fit to
retaliate
against neutral comments and lie in their response.
Just a heads up for anyone that would wish their purchases not to be
senselessly
placed at risk of damage before you have ever even received it.
i have had the pleasure of making a trip with Dave McGuire to rescue some very
nice PDP-11/70 boxes. what were not expecting was the volume of stuff that we
were presented with. being the people we are, we could not just flat out say
no, we had to take it all. it filled a 24' truck. that's a lot of PDP-11/70.
in the pile of stuff was a bunch of LA36 and LA120 terminals. only one of the
LA36 terminals powers up and DTRT, the rest are assumed to be dead. this is
WAY more stuff that i can deal with, so i need these dead terminals (including
a dead LA120) as well as the working LA36 and four CRT terminals gone from my
house as soon as possible. i am not one to lightly toss things into the skip,
but if these are not recovered from my house in a timely manner, i fear i have
no choice but to do so.
ok, quick run out to the driveway, and here is a list of what is there for the
taking:
1 LA120 (assumed broken)
4 LA36 (assumed broken)
1 LA36 (seems to work)
1 Qume QVT-101 CRT terminal (powers up, seems to work)
1 Qume QVT-201 CRT terminal (powers up, seems to work)
1 Qume QVT-202 CRT terminal (powers up, seems to work)
MicroTeam FE 4520 CRT terminal (powers up, seems to work)
Diablo 620 (untested, has the extra tractor assembly)
i think i have the keyboards for all the CRT terminals, but i'd have to check.

ps: some pics of the PDP-11 haul, as well as moving my large collection of VAX

Roughly. My Mullard 1977 Data Book lists as equivalents
12AT7 ECC81
12AU7 ECC82
12AX7 ECC83
12AZ7 ECC81
but I notice that my 1976 book lists ECC81 as obsolescent! You can still
get them, though. That's a long obsolescence period! There's not much
difference, actually; ECC81/82/83 are the same except for gm, mu, -Vg and
Ia:
gm mu -Vg Ia
ECC81 5.5mA/V 60 2V 10mA
ECC82 2.2mA/V 17 8.5V 10.5mA
ECC83 1.6mA/V 90 2V 1.25mA
And I found the 12AT7 data elsewhere:
12AT7 5.5mA/V 55 2V 10mA
The small difference in mu between 12AT7 and ECC81 might just be the result
of minor differences in measurement techniques or manufacturer quality; I
read something that suggests the ECC81/82/83 were designed as exact
replacements for the 12A?7 series.
All data refer to 250V anode voltage. Those dual triodes are/were often
underrun at 150-200V, and obviously the gain and currents etc change if you
do that.

If you're running Windows, you want Cygwin (http://cygwin.com) which is
a unix environment foe Windows, GCC, bash shell & everything (even a

"Unix environment foe windows"?

price seems reasonable (for a change!). It actually

My sister and I used to have something along those lines. It was a mini
record player/slide projector. The records were hard plastic or vinyl,
and they came with a stick with slides on it and a book. You would play
the record, and insert the slide stick. The record would tell the story
in the book (not word for word if I remember), and every time it would
beep you would pull the slide stick up one notch (maybe pressed a button
to do it for you, don't remember).
Somewhere in a box I still have some of the record/slide/books, but the
player is long gone. Some day I hope to find a new player at a flea
market.

Yesterday I finally got a couple books I'd gotten on eBay a couple weeks
ago, obviously "VAXcluster Principles" is an interesting book, but I was
surprised how good of a book "The Digital Dictionary" is. I got the 2nd
Edition (the first was mainly internal use). It's a dictionary of all the
different terms that were in use around 1986. As such it contains info on
the PDP-10, PDP-11, and VAX, as well as DECmate's, Rainbows, and
Professionals. As well as the Apps, Languages, and OS's. Great book if
you want to know what a specific term or acronym means. Well worth picking
up if you are in to DEC stuff and can find a copy!

I'm just starting to fix up and restore a very fine old paper tape
reader, a GNT 4104. It's a photoelectric model and can go up to
1000 characters per second. It was originally used on a CTL Modular
One, and has the CTL logo and "1.32" designation.
Next, I'll have a look at the Facit 4070 paper tape punch. This seems
to be a common model, and there's interfacing info available on the
web. I also have a supply of blank paper tape!
What I need is a recommendation for finding teletype oil, or
something similar to lubricate the mechanical parts of these
machines. The oil on the machines at the moment seems to have
got very sticky, and nothing moves freely any more.
Oh, and I do have manuals for both of these machines.

Okay, I have a Victor computer and monitor. It has a single 5.25" floppy
drive. I've not opened it up but I suspect it's an early PC clone. The
monitor plugs into the back of the PC and has no power cord or other
attachments. The machine powers on, seemingly, but I get no display at
all. I don't have a keyboard for it either.
Anyone who wants it can have it, otherwise it goes to the recyclers next
week. I'm in Tucson, AZ. Please contact me offlist.

Having had next to no interest in the usenet groups, I'm cleaning out my
stash of Zorro cards and other Amiga goodies.
Included are:
Toaster 2000 cards, Flyer cards, A2065 Ethernet, A2091 SCSI with 2 Meg
RAM, PP&S 040 accelerators, and memory cards.
If you are interested e-mail me off-list and we can either go cash and
carry or trade.
I'm interested in SCSI-3 drives of more than 1 gig, an LCD display for
an Apple IIc+, or anything to make an A1200 into a towerized computer,
including case, slot expander, etc.

Back on June 9th of this year (Classic Tech Eletter #11), someone
thoughtfully posted the paragraph at the bottom of this message (on this
newsgroup). Coincidentally, I had already found the same S-100 computer and
I eventually ended up winning the bid (I was the only bidder). I only very
recently received this machine (it was slightly damaged in shipping, and it
_really_ was filthy! (There was an enormous delay in shipping it to me.)
I've got the damage straightened out and I completely disassembled it for
cleaning. I just got it back together last night and turned on the switch.
I seems to power up and the led's come on (led near the on/off switch and 3
led's on the backplane/motherboard).
I talked to one person who said that he thought that he'd had an ISC
computer before, but that it wasn't pure S-100. The reason that I bought
this machine is that I have some Seattle Computer Products S-100 cards that
I really want to get running. They drop in the ISC "S-100" computer
_perfectly_, but I have not powered it up with the SCP cards in place. If
there's something that's not "pure S-100" about the ISC, I don't want to
damage the SCP cards.
I just checked the link (below) and it still works. I think the link will
disappear in just a few more days (90 days), so I can provide the same
pictures to anyone interested after the link disappears. The reason it's
taken so long to ask this question is because it took over 2 months for me
to actually receive the unit (now the darned link is ready to vanish,
probably on Sept 10th).
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2029719366
I cannot find _any_ information about ISC Systems Corp., Spokane, WA. It's
an absolutely beautifully crafted unit and from the filthy condition that I
received it in--it appears to have been left running for, perhaps, _years_!
The seller claimed that he'd removed the existing cards to install in his
Altair, but if that's true, someone must have already substituted different
cards--in the pictures, you'll notice a bunch of twisted pair and other
small gauge wires: these all appear to hook up to what would seem to be
"non-standard" S-100 cards, through proprietary connectors. I cannot fathom
how the original ISC cards could have been of any use to anyone except a
user of this ISC system.
It appears that the "non-standard" wires go to things like: keyboard,
monitor, a network and LP 1 and LP 2 (LPT 1 & LPT 2??). There is yet
another connector that I've no clue as to what it might do.
_BUT_, _if_ the box itself conforms to the S-100 standard, and if I can use
the SCP cards, all the other wires don't matter, because they won't be
connected to anything. I've really taken a liking to this machine--I hope I
can use it!
Any help would be much appreciated!
Thank you,
