I still have a floor mount style MicroPDP11/73 chassis in Kansas City. I
used the machine several time but mainly it sat in the garage next to the
microvax2000 and PDP 11/23+. When I ran out of space because of 2 new
Microvax II's and extra disk drives I decided to sell it to somebody on this
list. I sold the boards and the purchaser didn't want the chassis because
of the weight and size. You all can fight over it, $10 plus you pay
shipping I'll provide packing and transport to the FedEx pickup for free.

The highest unsuccessful bid was also for $700 by
someone with a feedback rating of 232. He didn't
succeed because the winner had placed his $700 bid
the day before.
There were four bids for >$600, and one for $250.
(from http://cgi6.ebay.com/aw-cgi/eBayISAPI.dll?ViewBids&item=359971659)
I do think it was the well-written description and
all the pictures that pushed the price up into the
stratosphere.

Hi
Did anyone ask the bidders why they went so high?
There may be a valid reason. Looking at the other bidders
history, the next higher bidder was a regular buyer.
The winning bid was by someone that has made no other
purchases. He could have been a fake and wanted to see
how high things would go. I would be quite interested
to see how the sale goes through. The buyer has also
resently changed his handle. Makes one wonder?

Initially then it was dropped in price. I thik the 4k/L1 went down to
$399
and the 16k/LII was $599 later on.
Either way there were some 300-400 thousand of them sold! In the first
year of sales the total sold was 250,000! Rare, hardly.
What would be rare is a completely stock system with a real working
early model expansion interface!!!

Does anyone out there have a boot disk, software
and/or documentation for the Wang Professional
Computer?
I liberated one of these from a local thrift store
for the grand sum of $2.97 (keyboard, monitor,
and computer/drives all individually priced @ 99c).
It appears to be in working order--startup
diagnostics and the keyboard work fine. The
monochrome display is one of the nicest ones
I've seen.
An interesting note is that the startup ROM contains
an option to boot the machine from the serial port!
Thanks for anything anyone might be able to spare--
I am, of course, willing to pay shipping plus a
reasonable amount for the time involved, particularly
if someone copies me a boot disk.

IMHO, it's arrogant to think that ANY old computers (other than a few very
rare exceptions) are all that "valuable". If all the TRS-80s, ALTAIRS,
SWTPs, all the documentation, and software, etc... were to disappear
tomorrow, life as we know it would not change.
The reason that I collect is that I enjoy tinkering with and restoring old
machines. It has nothing to do with monitary gain, historical preservation,
mentoring children about the "old ways", or saving the world from the loss
of some irreplacable techno-saur. With the exception of "monitary gain" all
the other reasons above are BS!
Frankly I do have enough money to buy almost any computer I want and I do
buy from E-Bay. I also buy from garage sales, flee markets, thrift stores,
and other collectors. I have driven as much as 800 miles to pick up a system
that I particularily wanted but, I have NEVER paid too much. I've always
paid EXACTLY what I was willing to pay. The good thing about forums like
Ebay is that they give you the opportunity to set the price that you are
wiling to pay. If someone else is willing to pay more, so be it.
Sure I've been disapppointed because I didn't get a system that I was
bidding on but, so what. By the same token, I found a system that is the
only surviving member of it's species for $50. Is it irreplacable? Sure it's
irreplacable because there aren't any more. Would it really matter if I
tossed it in the trash? Maybe to a few people on this list but other than
that... not really.
Before anyone goes on another rant about throwing a machine in the trash,
let's take a poll:
Assuming I was to offer it for free, who on this list (other than captain
napalm who's only 10 miles away) would drive to South Florida to pick it up?

While it really helps to have "live" organizational skills,
I think a group of organizationally-challenged folk could
do wonders if they had a roadmap to follow, and from the
sounds of it, you & Merle & Co. have put together something
special.
Have you considered writing up either your experiences in
putting the RCS/RI together, or even better, something
closer to a step-by-step guide to finding the interested
local parties and what to look for in terms of facilities
(lots of space & separately derived 3-phase power systems
are obvious; other things are less so).
It may never happen here in the Louisville area (whatever
critical mass of interest is required may or may not be
present), but I'd like to try getting it started. We have
a Museum of Science and Technology, but it's all mass-public
stuff, IMAX Theatre, etc.

Obviously you are looking in the wrong places if the price of equipment
is too high for you nor are you looking at the "big picture"...
Sure, I use eBay, but only for stuff that's cheap, if it is too
expensive I look for things other people don't know about or haven't
thought of collecting yet. (My BASIC games book collection is doing
nicely, thank you.)
If I can't get stuff on eBay cheap, then I scour the thrift stores, yard
sales, newsgroups, shows like VCF, etc. If computer X is too expensive,
I wait, heck, in 5 years I'll probably get one, I'm in no rush...
(thats how I got most of my computers cheap, either buy it new in stores
or wait a few years till it's lifespan brings it to Salvation Army...)
Also if you have the webspace available - do justice to your favorite
collection and help others, this is not only a status symbol for the
collector but also let's visitors know that if they clean out their
closet of classic stuff/info, there is a place they can send it to who
will appreciate it and use it to assist others. (yes, I have received a
few contributions and am very appreciative.) But of course if you fall
into the "beanie babie" - collect for investment croud, that advice is a
moot point.
There are alot of aspects to a computer collection, not just the
machines; there is the software, cables, controllers, peripherals,
manuals, books, magazines, ads, stickers, buttons, etc... (in fact some
of the software, manuals books and magazines are probably more rewarding
to find than some of the computers...)

If you can afford it, go. My point is that despite organized

You know, I could get really angry at this last remark, but it just
makes me sad. (Retro)computing was a 'joy' thing. It was so
awesome because just about anyone could experience it. It was
really something special because it's only major cost was the time
and effort you put into it.
What really mattered was what came from the heart, really.
What really matters now, is what comes from the wallet.
I guess it really wasn't so special afterall.

Jeff, I'm using your quote as a starting point, please
don't think I'm picking on you.
Well, somewhere between rich and poor (I tend to count
myself the latter), there must be middle ground. My
current focus is on Primes, and I'm playing fast-and-
loose with my bills (as well as selling things I'd
rather keep) to try to get this system to a certain
point where I'll feel comfortable with.
However, had I managed to save that MicroPDP-11/73
>from the Jaws of Greed, I would likely have simply
held on to it until I could find a better home for
it. Strictly speaking, I'd say that's collecting
and not preservationist. But at least I'd have kept
it from the landfill.
Ideally, the poor collectors amongst us can do
lots of that. But I think it's incumbent upon us
to be ready to give up posession to someone who
can do the item more justice than we can.
I think a phrase commonly stated about relationships
might be applicable here. Rephrased: If you love
something, let it go. I'm letting go of at least
one of two unfinished SOL motherboards very, very
soon (but my original working SOL I will keep).
As to the rich: by virtue of your economic power,
you might easily fall into the trap of compulsive
acquisition. Fewer constraints hold you back, and
so the ID runs wild.
Had the Evil Lurker been restoring a personal system
with the parts he was looking for, it would not have
bothered me a wit. I'd like to take solace in knowing
there's a good chance someone restoring a system will
see the parts he has for sale, and buy them. But I'm
afraid they'll just enter a nonterminating speculative
loop.
So, to the rich, let me say this: try to be aware of
what's going on around you, and if you see you're
trying to acquire something that some poor guy is
also going for, remember, this may be his only chance,
and you'll likely have another. And to the poor guys
(like me), I say: be willing to give something up
to someone who can actually get it going sooner
than the 20 years it might take you due to your
more limited financial resources.

If that's the only choice- landfill or reduction to parts- sure,
reduce it to parts.

I appear to have been guilty of projecting, in this
case, reading into your previous remarks what I was
feeling.
Sorry.
I'm desparately looking for parts, but I'd sooner
cut off a limb than rob them from a working system
until _every_ effort has been made to find a good
home for that system. This one appeared to be lacking
an OS (or anything for it to reside on) but I see that
as minor compared to systems with disfunctional stuff
in the backplace.
But I gotta admit, I'm making way too much noise over
a doggone PDP-11 when they aren't my forte to begin
with.
At least I get the tape drive.

On the gripping hand, I know of some "collectors" (as
in they acquire large amounts of stuff without looking for
commercial gain) who will, for example, rip all the boards out of
a working VAX 8650 but leave the chassis behind, because they have
no way of hauling the chassis cabinets nor a place to put them. As
far as I can tell, nobody wins here, because a working 8650 was turned
into a pile of nearly-worthless parts that will simply sit in the basement
for a couple of decades. Does this stop the offenders? Of course not!
Tim.
Chuck was right about the guy that won the bid on
the MicroPDP-11/73... the buyer's name is Chris
Hoaglin, and all he is interested in is f*cking
up a working computer to end up with parts he
can sell to fund his greedy little schemes. He
wants the backplane and all the cards. I wish the
seller would have said NO, but that was not to be.
FWIW, I was going to steal one part- the plexiglass
door of the TS05 tape drive- to put in place of
a broken one on a Cipher. The broken Cipher door
works, even broken, and will still work when glued
back together- it will just look like sh*t. How-
ever, I would have either preserved the system in
all other ways, or even tried restoring it.
Well, souless b*st*rds are prolifigate, and some
are circling overhead like vultures.
The only good note: I'll get the TS05 for US$5.00.
I doubt I'll take the rack. Perhaps someday I'll
need a part from the TS05 (assuming it *IS* really
a Cipher streamer inside).
Oh well. Hi ho.

Do we need 'true historical preservationists'? Maybe. Does that mean
that the priorities of the 'true preservationists' will be the same as
those who actually worked with the systems or still use the systems?
Of course not. In fact, the priorities will probably be vastly different
between the two groups, and this is all the better reason for both groups
to co-exist, probably with at least a bit of animosity towards each other.
How do priorities differ, even among "hobby" preservationists?
Several ways:
1. Some insist on a pristine as-shipped-from-the-manufacturer system,
with no third-party peripherals or software, and others realize
that in real life there were very few such configurations
and instead preserve the systems as they were actually installed,
with third-party peripherals and software abounding.
2. Some only care about CPU's, and will travel hundreds or thousands
of miles to pick up the CPU box, and leave the peripherals
(necessary to boot the OS!) behind. Others put more emphasis
on getting a few complete working systems rather than a bunch
of CPU boxes that can't ever be booted.
3. Some haul away hardware, and leave a mountain of magtapes
behind with the operating system, etc. Others haul away hardware
and tapes and disks but leave the books behind. Others just
want the books, others just want the tapes.
I've seen every single one of the above characteristics exhibited by
"amateur" collectors, and every single one of the above possibilities
exhibited by "professional" collectors.
Personally, I fall into the "put any old hardware together that makes
a system work, don't care whether it's original or third party, get
complete systems with peripherals, and spend lots of time archiving
the software" category. Every person on this list probably falls
into a different category. I may not agree with everyone's priorities,
but in some sense a wide range of priorities from a wide range of people
is a *probably* a good thing.

I went back and carefully read what I posted; a strict deconstruction
of your phrase "questioning a vendor's integrity" does not seem to
apply to what I said. I thought the tone of my post was respectful
if somewhat apprehensive. I did not question his integrity; I merely
related my experience and queried others as to theirs.
And as to waiting two business days, let me say this. We all
tend to expect instant results from anything involving a
computer, forgetting that a human component is still in the
loop that doesn't respond at the speed of light. However, I
use delivery and read receipts on all my mail, and if I at
least get a receipt back, then I know I'm most likely "in
the queue". Failure to receive same leaves me wondering if
my message was even received. Not all ISPs and mailers support
receipts, I know; as to the ISP problem, scripts can provide
the equivalent function. For mailers, all that's required is
to switch to a different mailer. If anyone finds the receipts
distasteful, they can decline to use them, but they risk what
almost happened in this case.
To summarize, had I gotten a receipt, I'd have waited as
patiently as is possible for me, but I'd have waited.

Bzzt. Sorry, nope. The power supply is driving two diff SCSI drives

Before I quit I tried to get that sound... no idea how he did that.

Majorly cool color.
someone with a Tarbell cassette interface to read. I never had the

I ment to. The cut FYI from playing with other "floppy roms"
has to be very clean and right on pitch. IA or was it byte did
a few of them as tryouts. Marginally successful.
I'm not familiar with Subotnick. What is his style? Is it more like

It's not enough to just will your collection or some

unless you also provide for the shipping/transport

themselves.

Did a bench test w/o the amiga, and didn't see any smoke (good sign?). I
heard the HD make its expected noises, so at this point in time, I think the
PC part works. Might have a prob in the shared memory part going to the
Amiga. I have to clear out an area on the bench to set up everything.

Very true. I remember trying to give some stuff (a bunch of
42" racks, old 14" disk drives, etc.) away five or so years ago, and
nobody was interested. But then I attached a price and got several
folks to show up to take it away.

I saw that one too--it had to be the description!

Subject: $700 TRS-80???
Can anyone explain to me why a TRS-80 model 1 level 2, no expansion
box or floppies, just the base unit, ps and monitor, would sell for
$700 US? There were several bidders willing to go over $600.
There are several more, more complete, systems on ebay right now in
the $20-$60 range. There's also one with a $460 starting bid and
no bidders. Is there something I'm missing on this one?

But what a coincidence that I'm planning to put a Tarbell

be $100, and while it does not include documentation, and
I have not tested it, I am including a 1983 Tarbell Electronics

Did you tell him that computers are an investment that don't normally
appreciate from their original purchase price (with the possible exception
of Apple Is and Altairs)? Tell him I'll sell him an equally collectible
Amiga 1000 for a very reasonable $2500.
Seriously though, if anyone on-list want an original A1000 in its original
box, with original keyboard but a replacement mouse (copies of Kickstart
and WB 1.2 included, no manuals) I have one available. I'll take Amiga or
Atari ST software (or most anything else Amiga-related) in trade.

Your dates and music are misaligned. the "Walter"

up or down. It was a itlem of convenience of the record
compmanies. However by then it was history.
I know as I have all the albums as originals bought when
they were originally released and have kept a Yamaha

> Has anyone done business with Richard Meyers

Ok, I called him, he called me back, VERY busy
guy, good intentions, is sending me another unit.
He tested this one to make sure it at least spins
up (it was strange that while the auction ad made
no mention of whether the drive had or had not been
tested, that they still offered a 2-day DOA warranty).
For my part, I'd decided that if a second unit is
bad, hey, it was only $15.00, so no real harm done.
But getting a working one means a lot, so I'm
hoping this one will be good.
At any rate, I feel safe saying that this guy
runs a good business, and I'll probably buy

Has anyone done business with Richard Meyers
of Meyers Computer Services (Jersey Shore, PA)?
Here's why I ask...
After the many invectives launched here towards
E-bay (but prior to my post defending them), I
decided to check out haggle.com. Almost right off
the bat, I found something I wanted for a great
price- a Seagate 11200ND diff SCSI drive. I won
the item, and received it on Wednesday.
It was Friday before I got around to trying it-
and it's DOA. Won't spin up; I can hear what might
be the heads trying to unpark, or maybe it's the
drive motor trying to start. But negatory.
Additionally, three SMD devices appear to have been
removed from the drive's interface PCB. Very strange.
I sent him e-mail on Friday w/r/t its status as DOA;
the description for the item gave it a 2-day DOA
warranty. He appears to be very busy; I spoke to
a subordinate, who took my info and said he'd
contact mr. meyers about it, and I'd be contacted
back.
All the feedback on haggle for him is glowing;
I'm willing to believe he really is a busy guy
and that he (or a subordinate) just grabbed a
drive off the wrong pile and shipped it to me.
An honest mistake.
Should I be apprehensive about this? Hey, I'd
only be out $15 if I get no resolution, so it's
not going to be the end of the world.
Just thought I'd ask before I cop an attitude...

I got a Prime 2455 for shipping costs only; the owner wanted...

Pads for unplaced devices have a decidedly different
appearance (in my experience) than what I see here.
Usually, the pads are shiny with solder, a remnant
I assume of wave soldering or some other similar
manufacturing technology. For a given device, a
few lead pads will be shiny, some *black*, and some
kinda look lke they've been pulled up off the board.
Sombody had a steady hand, I'll say that for sure.
Either that, or these chips blew themselves off
the board.
I wish I had a photomicroscope so I could take a
picture- you'd see what I mean.
As I said in my post, I'm assuming he gets lots
of these, and he just grabbed this one off the
wrong pile.

I wish. I don't actually have one of these power supplies in front of
me right now, just a couple of so-so printed copies of photos showing
what it should look like with the top cover off. One photo for the
configuration that supports battery backup, one photo for the

You can see the latter (which shows what I think rdd has) at
http://www.reanimators.org/tmp/1000E-ps.jpeg -- it's about
50KB. Maybe this will help you more than it helps me.
What I don't see in the photos is the big transformer-like hunk of
iron that I'd expect in a linear power suppply, and the dark spaces
don't look big enough to hold one. So I'm thinking it's a switcher.

Hello All,
When I create an empty RM03 under Bob's emulator witht the badblock
option and then mount it under RSX, it complains, telling me that
it is an alignment pack! Is there a way to get around this problem?
Using FMT does not help either, a similar message is returned.
When using RT-11, INI doesn't do anything, it just hangs.
Thanks,
Ed

John Wilson asked:

Pre-V5.5 versions of RT-11 come with the "DP:" driver, but this
doesn't do RM03's, just RP02's and RP03's. It wouldn't suprise
me if it got confused when you hooked a RM03 (real or emulated)
to a system and tried to access it with the "DP:" driver, but
that's "operator error".
There are several DECUS-distributed RM03 device drivers for RT-11,
and there were also a couple of commercial ones sold by third parties
in the 1980's. The most likely DECUS driver is library entry 11-517,
"System Device Handler For RM02, RM03, RP04, RP05, RP06 and RT-11 V4".

So, I want to thank everyone for the very useful

my interest in DEC is pretty much limited to the
DEC-10, and since DEC had enough trouble keeping

one.

Point to John: the machine offered for sale is called an
IMSAI Series Two, not an IMSAI 8080. However, its arguable
that many existing IMSAI 8080s ceased being IMSAI 8080s
when the owners stuck in a Cromemco ZPU, a TDL Z-80 CPU
board, or somesuch.
However, quoting from the main web page:
: Delivery is currently 6 to 8 weeks from the date of order.
: Please check with us for confirmation of shipping date.
:
: Assembled IMSAI products are shipped factory assembled
: and supplied with a no-hassle two-year warranty on parts
: and labor UNLESS specified otherwise. See the warranty
: details on our ORDER page.
Now, I don't have a kilobuck laying around with which to
test these statements. But as to my original statement,
clearly, people spending $1200 for an original either
have little interest in running the thing, or, at very
least, want an "original" more so that they can say it
is an "original" over and above its value as a working
system. If its value as a working system is more important,
they'll consider buying the Series Two.
And if the Series Two is still vaporware, then all I can
say is that is a _very_ old tradition in the microcomputer
field, and I think I'll have to write up my experience with
Processor Technology and the Sol as an example of this (I
still have all the "soon" letters I got from them).

...I think you may be right. The flowchart goes on to ask: "Is >= 0.6
Volts measured from A3A6TP1 to A3A1TP1? WARNING!! Use VM with
Floating GND". If the answer to this question is no, you're supposed
to replace the preregulator board (A3A1) or the control board (A3A5).
Else, the next question is whether fuse A3A6F1 is blown or missing,
in which case you're supposed to replace the fuse, else replace
transistor A3A6Q1.
Then you go back and look for +5V CPU on the crossover board again.
How to decode some of those numbers:
Leading A3 is the power supply.
A1 is the preregulator control board, which is a vertical board
plugged into the power supply motherboard just behind the terminal
block near the front of the 1000E.
A5 is the control board; it's the vertical board all the way at the
back of the power supply.
A6 is the power supply mother board. A6F1 looks like it should
be a fuse a little bit behind A1, and A6Q1 looks like it should
be the largish transistor closest to that fuse.
> > adjustment is the +5V ADJ potentiometer that is visible on the power
>
> Does adjusting that make a difference with any of the other voltages?
I don't know. The next couple of tests that the flowchart takes you
through are simply "is <some power supply voltage>" in tolerance at
the crossover board?", and if the answer is "no" then you get to
replace a transistor on the power supply motherboard, or in one case
the power supply motherboard.
> What's the difference between M and I/O in the supply v. column?
I think M is the supply that goes to the memory bus, and I/O is
the supply that goes to the I/O bus.

Yep.

As Tony points out, there is stuff in there that can knock you on your
hindquarters or worse, and I'm guessing that's why you're supposed to
use a voltmeter with a floating ground in one of those tests above.
Be careful.
That said, sorry to take so long writing back, just haven't had time
or space between my ears to sit here with the manuals and try to
figure things out from them. The curse of gainful employment strikes

Actually the S100 was cleaned up a bit and would run nicely at 8mb/s
for split or 16mb/s for unified word mode.

Typical system with a HD in the 79-81 timeframe liekly had two CPUs
one for the HD alone! Teletek, Konan for example. There wer floppy
cards with local cpu too to further unburden the main cpu.

You can buy a brand-spanking-new IMSAI 8080 that has 1 meg
of bank-switched static RAM and a 20mHz Z-80 (actually Z-280?)
processor for under US$1000. I'd say that qualifies for an
excellent "old" new computer.

using a standard Z84C010 (cmos 10mhz) and common cache rams I could
easily do a z80 1mb 10mhz machine. It's not hard. Use a Z180S00 and
33mhz
is possible. With cheap, dense fast static memory most of the old
designs
get real simple and can go faster. The best example is a proto I've
build using
a Z84C50 (z80/10mhz with clock + wait state management, 1k ram) in a
clone
of the amproLB using static ram (eliminates 15 DIPS) making is a fairly
bare
board. It runs at 8mhz due to limits in the SIO and CTC parts I had. I
wanted
it to run the same boot and BIOS so I used what I had.
If I were to do the latest and greatest I'd go with Z380 as it will run
Z80 native
and make the IO a z180 slave, then the only limits would eb the how fast
can
the Z380 go (20mhz is common part and it executes Z80 instructions in
about
half the clocks).

You can but, the reliability of the read data sucks to be blunt.
I said that you ccan do this in an earlier post if you needed
some special project hack to get you by. I don't as a good 48tpi
drive does a far better job and swapping it is no big deal.
I used 5.25 96tpi two sided double density for one reason easy to get
and use storage space. That mode does 720 or 782k depening on
the formatting were an older 48tpi drive will do 360k. Where 1.2mb
used funky media, data rates and all that are not easily found on
NON-PC systems.
Back in the old days using DD on a 96tpi drive was called QD.
>Hey, precisely what jumper is that?
I ave five different versions of the FD55-GF drives and they are all
different. So I did a lot of guessing and tried them until it worked.
A manual would have helped. I also ahve a few FD55Fs (also
96tpi DD two sided without ability to do the oddball 1.2mb format).

First Z280 didn't need bank switch as it had a 24bit MMU. Second if
it has Z280 production would be hard as Zilong endof lifed it some 6
years ago.
Likely is Z180 or Z380.

Does setting that jumper cause them to write double-tracks,
then (as ISTR that the HD drives wrote tracks that were
half-width, and someone used to sell a software package
that wrote an HD-width track, stepped the head, then
wrote an adjacent HD-width track to create pseudo-DD

In 1982 that was a low end example. DECs VT180 was a 4 serial port,
4mhz,
no wait states With DD floppy design. It was ment to go in a VT100 so
video
was not needed. My NS* S100 crate in 1978 was running at 4mhz even.
In the z80 world there were those that used Z80 peripherals and live with
the limits they imposed and those that went with other parts. What was
the
limits? Price, they were not cheap and they were SLOW. By 1982 a Z80
not running at at least 4mhz was considered slow and by 1983 that would
be 6mhz. Parts existed to do that.

Try a Z180 part at 33mhz, SCC or other all on one chip like the SMC92667
and static ram on a 3x4" board. Takes very little glue to do that.
The question goes mroe to price and creative engineering.

For pre micro processor...
there were designs that did thig with transistors and later SSI that were
way ahead of the pack so the answer was yes and no also.
For the z80 case:
Yes and no. Some designs the designer was doing the best they could
though the parts were more capable. Many cases the goal was to meet
a price so that limits you. There were some very capable designs.
But, using the same parts you could have done better then assuming the
budget
(size, power, $$$$) allowed it.
Can you do better now using current parts and reusing old z80s, yes.

I haven't used my MicroVAX II in some time, and one of it's RA81s wont
spin up. It starts to spin, for about 1 second, and then cuts out and,
after pressing the 'fault button' it leaves the fault light on and the
'B' light flashing. According to the RA81 user manual the cause is
'spin error' (I could probably have told _them_ that ;-).
Can anyone give me any advice on whether it is possible to resurrect the
HDA? If not, I have another drive which has no fans so I can make a
good one out of the two but the one which has gone down contains my only
copy of VMS. Is it drag in the bearings which is causing it to cut out
whilst the motor is accelerating it? If so is it possible to lubricate
them without opening up the HDA?

Well you left out all the caveats.
I do it all the time, no problem. Key thing is while the drives
are HD capable (TEAC FD55GFV) I happen to have them
jumpered as required to properly run DD mode. In this
mode they are plain DD, DS 96 TP! drives.

The long and short of it is nearly none and everything.
the are the same mechanically, same boards, same drive
same for everything save two things... SCSI address and
one does not talk modern SCSI software protocal. IE:
the difference is firmware on the SCSI to TK50 board.
FYI: one is specifically for MV2000 and the other is useable
on many later SCSI systems (other than MV2000).
What I've forgotten is which is which.

NO majik, the darker HD media is for 1.2mb use and the ligher brownish
media is for all others. the other half is do not use 96tpi drives to
*reliabily*
write 48tpi media or the reverse (special projects and emergency cases
may be a reasonable exception).
If all else and it's possible, upgrade the drive used to a 3.5". Some
systems
can do this easily some can with some programming work, some cannot
easily
be modded.
Above all else keep media in a cool dry place, avoid direct sunlight.

I think that the original idea behind that compartment was that TI would release vocabulary modules that would fit in there, but I could be wrong. I saw a working TI-99 at a thrift store yesterday. It has a power supply, but I didn't get it because I already have one. I'll see if I can pick it up tomorrow. If so, you can have the power supply.

I would appreciate some help from anyone who knows
about the difference between a:
TK50Z-GA and a TK50Z-FA.
I am able to get a TK50Z-GA working under a SCSI host
adapter (CQD-220/TM) on a Qbus system (I set the SCSI
ID=4) and I see a standard TK50 tape drive under RT-11.
But, I also suspect that the TK50Z-FA is probably broken.

Ah but, they were available, LAPLINK, lantastic and ohers were around. It
wasn't
cheap but the SHARE.EXE was part of dos 3.3 and later. Compared to the

True but you left out one thing. Their total goal was a Plain Engilsh
license.
I read the DELPHI-5 (current) and it's understandable. Read some of the
MS
licences or others and time for an asprin.

They are close with MSN being a backbone and IE being part of the OS.
For some here that may remember. Back when, There was ABC TV, ABC FM
radio
and even ABC AM radio, all one company and network (same for NBC, CBS).
The
FCC saw fit to break that up as it represented a monopoly on
communications. Yet
we have MS (OS, APPS, content and Browser), MSN their network, and so on.
Think about it.
As to Mentec, a simple low cost non commercial license for what ever
OS/Apps
they currently own copyright to would be nice. Further a package of
media,
manuals and license for current (or one back versions) non commercial
without
support for a reasonable price would be attractive. then again I have no
idea of
the current price of a copy of RT-11 (Docs, media and commercial license)
goes
for.

I didn't write that but I essentially agree.
Consider this you buy a book, you own it to dispose of how you wish
(sell, give or burn). You don't buy a license to read it or X many friends
to read it. It is property. The copyright means you can't make copies
of it (other than limited amounts for reference with attribution) to sell

The idea of XYZ Co OWNING the software (copyrighted) is quite old and
may preceed the 1960s! At one time computers were only rented. DEC
was one of the first to alter that by selling machines outright.

That price isn't very high :-). Admittedly, I get them straight from
the manufacturer in large lots, but the price is roughly one-fourth what
I was paying in the early 80's, and that isn't even taking inflation
into account!

Occasionally I find a wholesaler going out of business and selling
thousands of boxes of 'em, at prices as low as 10 cents a box. But
barring such a surplus find, you can buy them brand new from www.buy.com.
At the moment you can get Maxell, Imation, and Verbatim at $4.95 a box

The Imation floppies I've gotten from buy.com were produced in the last

I have to make one point here, then I'll slink back into lurk mode.
Using the book analogy would not necessarily mean that your licensed
software was legally bound to the *CPU* the way the contents of a book
are bound to the paper. Making it legally bound to the CPU would be
like making the contents of the book legally bound to the room in
which you read it; you sell the house, the book goes with it; you
want to sell the book, sell the house.
Wouldn't it make more sense to have the software contents legally
bound to the original media on which it was delivered? This is how
books work, and (I think) how most people expect software licensing
to work.
Licensing to the CPU was just another way to make sure nobody could
every reasonably transfer their license to anyone else. If the book
publishers did that, they'd be.. uh... out of the mass market.
(How many publishers engrave their work into house walls rather than
print onto paper? And how many engravings of novels have you bought
>from them lately?) Thank God the market rejected it!
My point it, software *could* be licensed the way the contents of
books are; it need not imply any ill-conceived notions that hinder
transferrability, such as binding to a CPU. The holder of the original
media could be the legal holder of the license, just as with books.
The book analogy could work just fine, and the market has *not*
rejected it.

> >GENIUS GENIUS GENIUS GENIUS GENIUS
Ok, true story.
Ten plus years ago, in what so far was my last position as
a full-time programmer, we had a customer who required that
we be able to update their system remotely. The vendor who
had failed to deliver their materials handling software on
time was using Carbon Copy to handle that update & support
function.
So, suddenly, we needed to get a copy of Carbon Copy. I
wasn't in the loop on that, all I knew was that the boss
said I'd be getting this package in the mail, and to install
it on the PS/2 Model ?? (one of the desktop MCA machines)
that had the modem in it.
A few days later, the package arrived. As you might expect,
they did not go out and buy a new copy. Upon opening the
package, I stared for some time at the first page, trying
to imagine how it had come to pass that I was seeing what
I was seeing.
Apparantly, whoever (at the customer cite) had possesion of
the Carbon Copy package, delegated the task to someone who
was not quite up to it, but who did their best. I tried to
imagine the conversation that accompanied the assignment;
without a doubt, the manager handed the manual and diskette
to the delegate, and said "and be sure to copy the disk."
Because I was staring at a photocopy of a floppy disk. Oh,
and page two was a photocopy of the backside of the disk,
so at least the delegate in question was complete.
TRUE STORY!

Well, I corresponded with some folks at AMD, and didn't quite get
everything I wanted, but this might help somebody.
They have approved me making up to 10 copies of the Am2900 databook. My
plan is to scan it in and turn it into a PDF file. Therefore, I can only
make copies available to 10 people.
If you are seriously interested in a copy of this, let me know (John Keys - I
assume you'd like a copy, and already have you down for one). If you get
a copy of this from me, you may not redistribute it to anyone. You'll
also need to be patient, as it may take a week or two for me to get around
to doing this.
If substantially more than 10 people are interested, I'll go back to them
and request further permission, but this was all they felt they could let
me do without running my request through legal review.

Except that you can't use the software until you *copy* it into
your computer. The courts have ruled that it's copying whether you read
it into RAM or write it to a hard drive.

Yes, that's my preferred way for transporting H9642's when they can't

Mechanically, they're identical except for the nameplates. There may
be slightly different firmware/electronics, but these vary depending on the
F880 rev level anyway.

Back when the Mentec license became available, I took a copy of my
V5.3 kit and packaged it up for Bob Supnik so that he could get it
up on the DEC ftp site. Unfortunately, by that time there was simply
no-one from the RSX or RSTS groups left to do the same for those
systems. And now, Bob Supnik is no longer around, so I don't know
who to contact about putting stuff up on the site. Hopefully
Mentec could be persuaded to have an archive of distributions
available (once they actually allow the hobbyist use)...

Here's a question for the group. I have a PC running Bob Supnik's PDP-11
simulator and a PDP-11/45 front panel with no CPU boards. I'd like to do
sort of a faux PDP-11/45 with this setup by somehow wiring the front panel
up to the PC running Sim.
Am I completely out of my mind, or is there even the remotest chance of
getting something like this to work?

Best of luck :-)
Several months ago, one of our most senior members of staff (who has been
around a long time, and is perfectly happy with text mail, Unix, etc, but
has to use a PC for various reasons) sent several long messages to
'support' in mixed HTML+<something else> format, which caused some touble
for our support mail system. I politely advised him of this and he said
he'd fix it. Well, the next mail was still full of cruft, so I pointed out
that we don't support Outlook, and could he please stop using it or set it
properly. OK, he replied, in plain text. But the next message was in --
guess what! So I politely mailed him back, just to let him know. There
followed a long discussion; basically he refused to beleive his mailer
(Outlook) was sending crud because he'd reset it, tested it, and couldn't
beleive that his computer/OS could non-deterministically change its own
settings. We never did get entirely to the bottom of it, but it seems that
in some versions of Outlook, certain settings only apply to that session
(ie are reset next time you restart), and some settings are accessible in
two places, and you have to change both.
We still don't support Outlook, in fact we remove it from view in our
standard installs of Windows. But it's still there and people still use
it, and it's mostl OK so long as it's set up sensibly. The problem is that
Microsoft don't really understand standards like TCP/IP, MIME, DNS, ... (or
just don't believe in them).

Speaking of PDP-11 emulators and licenses ...
Is there anywhere I can get an RSX-11M distribution for use with Supnik's
emulator? The current Mentec license appears to permit this (at least,
for RSX-11M V4.3 and previous, or RSX-11M PLUS V3.0 or previous), but the
software isn't on the DEC FTP site.
--Pat.
Based on my experiences with System/36's, 8100's, and other IBM machinery..
the thing almost certainly has a welded steel frame. I took all the panels
off and the dual 14" disks out of a 5360, and I'll be damned if I didn't
only remove about 250lbs., tops. BTW, be CAREFUL picking up 5360's with a
forklift, they are very unbalanced by the humongous transformer on the power
supply end, my dad and I went to unload mine, and it started to try to take
a dive off the forklift attachment on our tractor.

Well, right now, it's not for certain I'll get it, since John Allain

I'll be using a pickup truck, and it's a single 42 inch high cabinet,

The system is in the hands of a sort-of-collector, not at its original
installed site. The photo shows a bookcase of what appear to be manuals,
but he may intend to sell them separately. I'll ask, tho, to be sure.

Hah, it will likely be in the high 80s or low 90s if I get the dang

I'll at least be transferring the plexiglass tape drive window
to the Cipher I have for the Prime. BTW, I asked the seller to
check the rear plate of the TS05, thinking it *is* a Cipher F880
and he came back and said it has only a TS05 ID plate.
The front bezel is *identical* to the F880 streamer. Do you know

No, but Sydex wrote a shareware MS-DOS device driver that used to be
available on simtel.net's MS-DOS collection, which supposedly allowed
the reading and maybe writing of HP150 stiffies in a PC stiffy drive.
Sad to say, I couldn't get it to work on my Toshiba notebook PC

Well you know, there a bunch of odd coincidences that revolve around
Arium, American Automation (now American Arium), the Regulus OS,
and the SS-50 bus (of all things).
It goes like this:
American Automation was a maker of ICE's and development stations in the
early 1980's. One of their products was called the EZPro-- it was a
general development system that could be equipped with a variety of
ICE's (I own a processor unit; I never located the 68000 ICE that came
with it originally).
Anyways, The EZPro was based on the 6802 CPU, and it used the SS=50
bus! It is the only piece of test/development equipment I have ever
seen or heard that used this bus. Around 1985, I contacted these guys,
and got a full set of prints for my system, and a couple of 8"
floppies with the OS, along with the source for the ROMs.
They told me that most of their EZ-Pro hardware had been *thrown out*
a few *weeks* earlier, that I could have had it, had I asked.
Ever seen a grown man cry?
They showed me their new product, I can't remember the name, but they
mentioned that it still used the ss-50 bus. I remember now that it
looked very similar to a product made by . . .
Smoke Signal Broadcasting (SSB), which made a 68000 based product
called the VAR. This thing ran Regulus, and was supposed to be
very good for real-time processing. SSB, if anyone remembers,
used to make a very nice line of SS-50 machines (The Chieftain).
Fast foreward about ten years, and Arium merges with American Automation
to become American Arium. I wonder if Arium based their earlier products
on the SSB VAR.
Spooky, huh?

What we need to know, is who (what corporate representative) was the
first person to capitulate to the robber barons by being willing to sign
a software license that granted only the right to use said software.
Once one corporation capitulated, the rest were bound to follow.
We could make that person number one in the Computing Hall of Shame.
