Hello, all:
I'd like to try to get my Mac 512k, Apple //gs, and IW-II talking
together. I have all of the LocalTalk (PhoneNet style) hardware connected to
the respective units. However, this is the first time that I'm attempting
any form of networking on my Apples, so I really don't know where I'm going.
I know that you have to identify one of the serial ports as LocalTalk.
I've done this in the //gs Control Panel, and I think that I've done this on
the Fat Mac, but what am I supposed to see? How do I know that it works?
Thanks again.

It seems I got these IBM model numbers confused. I think I meant the

709).
Eric, you seem to have quite some info on the Stretch; do you have any
source of (original or other doc) on this or the other early IBM computers ?
There is of course the book by Bashe et al, but I find it difficult to
locate more info.

My first thought was the pulling the battery, but someone mentioned that.
That leads to another notion that I don't recall anybody mentioning.
Assuming we solve all the 'ravages of time' issues, then we need to think
about another issue. As an ornery question, should we not pack along with
the machine a stone tablet? Engraved on the tablet is the following:
"This computer and operating system are not Y2.1K compliant!"
With no battery, the machine is going to present the date prompt. What
will happen when they enter '1-04-2100'?

It was definitely aluminum. The paint was chipping off in a few places, and
it definitely weighed a good pound or more than my Tandy 1800. Could it
have been a model that GRiD made for another company (as the label on the
bottom stated)?

I remember once seeing a GRiD 386 laptop that looked _exactly_ like a Tandy
3800, but was made of the aluminum alloy, was white, and said on the top
case that it was Panasonic (I think. The top cover was labeled with
something other than GRiD or Tandy). The bottom label said "manufactured
for {Company X} by GRiD".
Anyone ever hear of something like this? I was going to pick one up, but
they wanted $300 for one.

Could be any one of several models. If it really uses Bubble Memory, it's
probably a Compass (model 11xx). That, I'd pay a bit of money for, maybe
as much as $50 if it's working. More likely, it's a GRiDCase and maybe
worth $20 at most. If, on the other hand, it's a Convertible (2260 or
2270), you're talking real money again; I'd pay $100 for a 2270.

All those years of killing brain cells are finally catching up to me.
It's been a rough day and I wasn't thinking. Thanks for the info. I
don't really need another pc but you know how that goes....
If it turns out to be a 1535 (or other model with both the Gas Plasma
screen and battery power), let Derek Peschel know; he's been looking for
one for a while. (I have been trying to find one unsuccessfully for him.)
Aside from the bubble memory and the magnesium case, btw, the Compass was
the first of the clamshell style computers. Beat the Gavilan by half a
year at least.
(And no, the Gavilan wasn't the second clamshell either.)

The first GRiD was made in 1982, and I don't think we've been to the moon
since a bit before that. However, several models of GRiDs were used in
the space shuttle. Find out which model it is, first. The early models
are pretty hard to find (I think less than 10,000 were made).
If you're thinking of paying Real Money (TM), let me sell you one of mine!

Um, no. The teachers at my girlfriend's school (and all the schools she
works with) spend many (unpaid) hours every year planning the classes so as
to accomodate the differing needs of all their students. Things like
slower 1st graders are combined with advanced kindergartners so that
they're best able to meet the needs of all the kids.
There are many reasons why kids these days are not being educated as well
as they should be. Perhaps some of the blame belongs to the "System" --
any bureaucracy can thwart the best efforts of the dedicated -- and there
are indeed some people who should not be teachers.
BUT, Much of the problem, if not most, however, should be placed squarely
on the shoulders of those at fault: The parents[1]. (Aka voters.) No one
likes to think they've screwed up their own kids and done a crappy job as a
parent, so they blame the teachers. The politicians don't want to insult
the voters, so they blame the teachers too, and add to the bureaucracy.
Meanwhile, you have underpaid teachers, buying their own supplies, working
12 hour days, trying to teach kids whose parents proclaim "I AM NOT A
TEACHER!" on the kid's homework, and tell their kids that if someone does
something they don't like, they should hit them.
I've done some teaching back when I was young and stupid. I got smart and
gave it up because a) it's way too much work to do it right, b) it pays
pretty crappy, and c) kids are a PITA. Give it a try, and then come back
and tell me it's the teacher's fault.
[1] If you read to your kids every day, spend your non-working time taking
them to museums, plays, camping, etc., work with them on what they're
interested in, even if it means giving up watching football, spending time
with your friends, and so on, then this doesn't apply to you.

I have a line on quite a few GRiDPad 19xx computers. These are the
keyboardless slates sometimes called "post-it" computers, due to the ease
of just sticking them on a wall or anywhere convenient. I believe they
were also used on the shuttle at one point. They are DOS machines, 8088 I
believe.
These machines appear to be in pretty decent shape, with nice cases. The
ones I saw were 1910's, but there may be some 1900 or other, similar models
in the bunch. They are untested, and I don't know if they come with pens
or not.
I think I can get them for $15-20 each. Shipping in the US would probably
be around $3-5. Figure less than $25 total. (I will seriously try to get
them for less, and I won't be making anything on these.) If there is
interest, I'll pursue it further; if not, I'll grab a couple for myself and
let the rest go whereever they want.
Please reply off-list! (We don't need a zillion "I want one!" messages
spewing all over the 'net.)

Yes, the Germans had good maps of Britain. At Bletchley I say on display a

Unique. But not so distinctive. Stonehenge is obviously Stonehenge.
Salisbury Cathedral is random_large_church_with_tall_spire. Seriously, if
I emerged from cloud somewhere in the South of England, and saw Stonehenge,
I'd know exactly where I was. If I emerged and saw Salisbury, I could
probably work it out, but it would be a lot harder.
But the original report - that Stonehenge was flattened - looks like a
clear case of local telling tall story to American tourist...

To be pedantic, also not paper. They dried the reeds and glued strips
together, rather than pulping them. No acid in the treatment for a
start...
Now, as for what the best paper is, not far from my parents' they still
make paper by hand at Wookey Hole Mill. Originally set up to recycle
cloth, they now import raw cotton from the US (recycled cloth contains too
much artificial fibre). But the treatment for the rags was to boil them up
in caustic soda (NaOH), not acid...
I think linen (flax) fibres make pretty good paper. Manila (?sp) fibres
make strong envelopes.
How about printing on Tyvek? That stuff's pretty indestructible.

I don't know whether you can get the stuff in the US, but in the UK slate
was used extensively as a roofing material until quite recently (you can
still get new slates, but most new buildings use modern composite materials
in roof tiles). Most building salvage places will sell you secondhand
roofing slates by the box. Not suitable for chiselling, though - better to
use some sort of grinding tip on a miniature hand drill.
Another suggestion. The Mormons claim their scripture was preserved on
metal plates (metal foil?) for well over 2000 years. You could ask for
specifications - alas, the originals have mysteriously vanished...

Let me answer the second question first, since it will be part of the
answer for the first question.
Each of the PDP-11 OSes have programmed requests/system calls/whatever,
which perform the operations for the user which are specific to that
OS.
A pure MACRO-11 program might have nothing in it which ties it to
a given OS.
But generally, programs are written for a specific OS, since you'll
probably want to do I/O or get certain info from the OS itself.
For example, RT-11 has programmed requests. These are EMTs which,
when executed, cause entry to the OS, which expects the arguments
for the function to be structured in a certain way and located in
certain places (for example the stack).
The various calls like .DATE, .READC, .MRKT, etc... are actually
macros which are defined in some sort of system macro definition
file, which is automatically included during the assembly process.
For RT-11, this is the file SYSMAC.SML, located on the system
volume, SY: In later releases of RT, there was also a much more
complete structure definition file, SYSTEM.MLB, which could be used
to reliably define structures used by RT-11.
RSX and RSTS have their own set of macros defined which expand into
code which ultimately execute and EMT, which is processed in a certain
way by those OSes.
Now, given that answer -- MACRO-11 is conditionalized in such a way that
it can be built to issue those calls appropriate for the system you are
building it for. MACRO-11 on RT-11 issues RT-11 programmed requests
to read from the source file and write to the object file. MACRO-11 on
RSX-11 issues RSX-11 system calls, etc...
The heart of MACRO is the same regardless of which system, but the
peripheral routines do what is appropriate for the given OS, and they
are governed by conditionals.

I've been going through some of my manuals, and in looking at the Macro-11
manuals it looks as if they're pretty much written with the intention of
being used with any of the DEC OS's. Is Macro-11 pretty much the same
across the various platforms or what?
If so, what makes a program written in Macro-11 a RT-11 program instead of
a RSX-11M program other, than the way that it is linked?

Do you see the 'DIGITAL' logo during the boot process? (Did you get
the monitor and keyboard?)

If it is off a Vax system, it will probably have a special board in
it for use in controlling that system. You won't need it. It will
also probably be running P/OS, not RT11, although you can get an
RT-11 to run on it.
There is also Venix, a unix-look-similar... You can also run a
version of TSX+ on it (TSX is layered on RT-11, so you would need
RT-11 first).

You'll need a monitor and keyboard, attached to the appropriate
connectors. The AUI port is only usable if you have a DECNA
ethernet adapter card in the machine. The communications port has
modem control. The printer port can be used as a debug console (if
the cable has pins 9 and 20 connected) and then runs at (I think)
4800 baud. This port is at the standard console address for a pdp-11,
but it doesn't have the same interrupt structure.
But the monitor and keyboard are required, since that is the boot
console. Without them, you won't be able to run anything.

My brother-in-law has found a Visual Technology Commuter
"portable" at a local thrift. It's operational and runs
PC-DOS 3.10, for which its previous owner thoughtfully
included a boot diskette.
This machine has an LCD display, and two 1/2 height
black face 5.25" floppy drives and 512K of RAM. Despite
a diligent internet search, this is all we know.
Does anyone here have any fond memories and/or pointers

Without going into a lot of extraneous detail.. I am on several
comittees and groups etc., involved in the restoration and
preservation of films, sound tracks, and video media.
All the high-techsolutions notwithstanding, one of the long-term
archival methods is still an optically-recorded signal on stablized
mylar or estar-based photographic film of some kind. With the
proper care in processing the film life is forcast to be in excess
of 500 years, and all that is required to 'read' it is a light
source and a photo-responsive device.. plus the algorithms to
recover the intelligence from the data stream. In the case of
purely analog info, an audio amp, speaker, (and knowing the
language) are the only recovery criteria. Data is a little more
complex, but hopefully in 2100 somebody will be able to translate.
Unless we've managed to reduce ourselves to cave-man status once again.

More information on the VAX 6000 at Bermans in California (408) 955-7908
This is a VAX 6000/330, sitting next to it is a TU81 Plus tape drive
mounted above an RA-82. All in the "low" grey/white DEC cabinets (two
cabinets total). Sitting on top of the TU81Plus are two boxes, one marked
VAXStation 4000 - 60 and one marked BA42A, the latter has a SCSI connector
so I presume it is the disk for the VAXstation. They are _not_ in this
week's auction so I don't know what happened there.

I powered up the THING today. It says it's a Stand Alone Terminal
Exorciser, PN 08309930, date 01/84. It passes the self test and brings up a
menu that lets you select 327X Tutorial, 327X BSC, SDLC/SNA or R-LOOP.
Selecting the R-LOOP option brings up another menu for 8775 Device or 3276
Device. That's as far as I can get in the menu, after that it asks for a CU
address or will autoscan for it but of course there's nothing connected so
it doesn't find what ever it's looking for. Does anyone know any more
about it?

Hmm. You're comparing CMOS with TTL. The traditional EPROMs are not TTL
but NMOS - very similar components (at the transistor level) to CMOS, but
fewer different sorts available. NMOS uses enhancement mode FETS and
depletion mode FETS of N-channel polarity. CMOS uses enhancement mode FETS
of both sorts. In theory, depletion mode FETS could be fabricated by the
CMOS process, but I've never heard of it being done except perhaps for
NMOS-compatible outputs etc.
So I don't envisage a difficulty here. The newer designs of CMOS parts
should compensate for any inherent disadvantages with CMOS technology.

But, when you consider things, most people wouldn't have seen what we
consider a "hard drive" for probably 40-50 years, if not more. By that
time, computers will probably be the size of, if not smaller than a 1999
hard drive. The computer in the time capsule will probably seem like the
ENIAC does to those who are accustomed to today's compact desktops and
laptops.
I just thought of something else: Is a modern, voice-coil-driven (heads)
hard drive even alignable? The old drives with the stepper were, but they
usually operated on the principle of a floppy drive (in the way the heads
moved, at least). In a modern drive, if the heads would somehow "un-align",
all you would normally have done is get the data rescued, reformat the
drive, and put everything back on, or, what *most* (not necessarily people
on this list) people would do, is just get the data rescued (if their job,
or life, depended on what was on the drive), trash the mis-aligned drive,
buy a new one, and re-install everything.

Slightly related to the subject of reading CD's in 100 years:
On one of their recent space probes, NASA put a DVD (just the disk, in a
little pocket on the outside of the probe, possibly with a plaque of some
kind but probably no directions on reading).
I suspect DVD's are much more complex than CD's. I would trust a CD on a
space probe more than I would trust a DVD. The records on Voyager (both
Voyagers, I guess) -- which include styli and playing directions -- strike
me as a MUCH better idea.

Eh? No it wouldn't. Never mind the mechanism, do a thought experiment.
Sorry Hans, I mean a Gedankenexperiment :-)
Assume you have a memory technology for which you expect half the bits to
get zapped in 20 years.
In another 20 years, half the bits will get zapped - but it won't be
selectively all the others. On average, expect half the remaining (intact)
bits to get zapped, and half the already zapped bits to get zapped. So
you're left with a quarter. And so on.
20 years is thus the half-life of an exponential decay.
Now with technologies like EPROM it's a bit more complicated, because the
zapping of bits is not a random (Poisson) process but depends on a decay of
charge within the device. But you get the idea (I hope).
Philip.
