This is semi-OT, since the IIsi has two years to go before it's on topic :-)
For a Commodore nut, I sure seem to be doing a steady traffic in Apples.
>From the same place I got the SE/30 and the IIgs ROM 3, I also picked up a
IIsi. After some cursing because it was set up with At UnEase, I rigged a
boot disk, trashed AE and started poking around.
It's an '030 with 5MB RAM running System 7.1. I'm finally seeing value in
the tuition I pay to Loma Linda University, since I basically went to the
System Folder on all their System 7 Macs and grabbed all the extensions and
control panels. Surprisingly, at least to me (the systems in question were
7.5 or later), this seemed to work EXCEPT for OpenTransport. PC Exchange
purrs like a kitten and I'm able to handle ProDOS and DOS like a pro. (By
the way, what files does ProDOS 8 need to have on the disk for it to be
bootable?) But the IIsi simply refuses to mount OT.
I downloaded 1.0.8 from the Apple support site and tried that, but it simply
said it could not be installed on this particular model and gave no further
explanation. The readme asserts that it will run on '030s and 7.1, though,
for all the versions available from asu.info.apple.com. However, they appear
to be updates, not installs (except for 1.0.8, the 1.1.x versions say that
1.1 must be installed already).
Simply copying the libraries and the Shared Library Manager into the
Extensions folder doesn't work. It just ignores them, and when I try to
start the TCP/IP or AppleTalk control panels, it whines that OT is not
running. Copying fresh ones from the "uninstallable" install disk doesn't
do any good either.
Any suggestions? I'm really hoping to avoid having to make the monster (for
this poor thing) download of 7.5+ from the Apple support site if I can avoid
it. I don't mind System 7.1 at all, really.

The SE/30 can handle 800K disks with no problems (unless someone changed

I have an Apple II Workstation Card that will let my Apple IIe, using
ProDOS 8, talk to ASFS. It is possible, but I have not done it yet myself.
Someday I will set up an AppleShare server for my Apple IIs but I simply
have not done it yet.

See the following site for information on ASFS v3:
http://lowendmac.com/tech/appleshare3.shtml.
I do not know where to get it. I just missed it once on Usenet; by the
time I contacted the owner it was already gone. It had version 2 and 3
with all the disks and manuals, too.
For more help, try Usenet at comp.sys.apple2. That's where I learned most
of what I know about networking Apple IIs.

Yes, I think the first upgrade was very soon after the launch. Ours all

Only the very first Indys; SGI very quickly (a few months) moved from R4000
to 4400 and then 4600, which are the same speed as, or slightly faster
than, the R4K Indigo. But yes, I'd forgotten about the original R4000PC
Indy, and that would account for the story.

That's certainly true, so I'm glad that one of mine is an XS24 and another
is an Elan, although the R5K might make a difference even then, or so I
hear on comp.sys.sgi.

It's a nice story, but unfortunately, only a story. I should know: I have

I don't know where you got this misinformation from, but Power Macs do support
800K floppies (apart from recent models which don't have a floppy drive and
perhaps the G3 models).
Every Mac previous to the Power Macs also supports 800K floppies (apart from
the very earliest ones which only had 400K drives).
See the "Power Macintosh 7600 Series: Technical Specifications" at
http://til.info.apple.com/techinfo.nsf/artnum/n19545
Other Technical Specifications documents on the TIL site for other Power Mac
series computers also contain this text:
* Internal Apple SuperDrive floppy disk drive
-- Accepts high-density 1.4MB disks and 800K disks
-- Reads, writes, and formats Macintosh, Windows, MS-DOS, OS/2, and ProDOS
disks
Also see http://til.info.apple.com/techinfo.nsf/artnum/n19545
This has a brief explanation on why access to 800K floppies is slower under
newer Mac models.

hmmm.... then it is possible that some cards are missing because
there are intermediate empty slots; here's the back cage

And yes, the big board underneath everything is the mainboard with

I did not move the cards around, but again, maybe some cards are
missing.
I don't know what OS the system was running.
I guess that the first thing that I have to do now that I tested the
power supply and verified that the machine (seems to) turn on,
is to build a serial console cable for this. I have several cables
that will fit the BACI boards, but the connectors at the other
end have been cut off. Does anybody have the pin out for the
finger pads in the front of the BACI boards?

I wasn't going to chime in, but now that we are benignly listing 1960s

who was producing it for NASA discovered its potential when employees were

Went to Chicago to visit relatives over the weekend but couldn't find any
decent used computer stores. Maybe they are in the suburbs? Highlight of the
trip was I stayed in a hotel, room 1337. ph33r hax0rs!
Went to the local salvation army and picked up an Atari 850 peripherial
expansion box, a Disney Sound Sources paralell port sound box (Funny) a few
assorted cables, and most importantly, a book on various expansion bussees
circa 1983. Covers S-100, Tandy, Multibus, TI/99, Apple II./III. Interesting
stuff, and cool pictures of wacky niche machines (The Heathkit LSI-11
Computer, The KIM-1) Happy Hunting!
If anybody ever asked me what cars could be compared to classic computers,
this is what I'd pick out:
System: TI-99/4A
Car equivalent: DMC Delorean
Reason: It looks like a Delorean, & is about as flawed.
System: Original Apple Macintosh
Car equivalent: Any Saturn
Reason: Way back when, Apple wanted to make you think that you were the wise
consumer. Saturn does the same.
System: Altair 8800
Car equivalent: Ford Model "T"
Reason: If you can't figure this one out, hang up your mouse on the way out.
System: Commodore 64
Car equivalent: 1957 Chevy
Reason: Name anybody who didn't have one of these when they were out! (both
the car or the system, that is)
System: Apple ///
Car equivalent: Yugo
Reason: None required.
System: Apple Macintosh SE/30
Car equivalent: 1967 Ford Mustang GT
Reason: The computer could haul, & so could the car!
System: IBM PC Jr.
Car equivalent: Edsel
Reason: See "Apple ///"
System: Apple Macintosh II
Car equivalent: Mack Truck
Reason: Large computer, large truck, 'nuff said.
System: Commodore Amiga
Car equivalent: Any Lexus
Reason: The Amiga had featues found on computers costing much more, likewise
with its comparison.
System: Apple LISA
Car equivalent: Rolls Royce
Reason: Self-explanitory.
Got anything to add? I'd like to see what you guys can come up with?

If I read my sentence (quoted above) out of the context of the thread
wherein the date 1700s had previously been stated, I'd see how that
interpretation could occur. But in-context, I still don't see it.
At any rate, it was an honest mistake, and multiple people made it,
so I guess we should move on.

If you want to archive old 16mm or 8mm movies then VHS is not the way to go.
My wife's uncle has made movies of family functions for the last 50 years.
I have watched them, lots of 16mm film loading and rewinding involved. He
transferred them to VHS about 5 years ago. We did keep the originals. We
have had lengthy discussions of how to preserve them for the next 50 years.
The 5 year old VHS copies are convenient to view but we can now start to see
the loss of crispness due to data bleed-through. There is also a loss of
color fidelity. We have discussed CD-ROM and other digital media. Our goal
is to keep them for another 100 years and then let the next generation worry
about them. It's amazing to see the progression of the development of our
lake community in the movies, members of our family have lived here for 72
years. Boats have changed a lot. We keep coming back to analog
photographic film, partly because of cost, mainly because of stability. I
am investigating how to save/archive photographs from our community that
span from 1928, no lake and no water, until now. Saving the photos is easy,
recording who is in them is the hard part. CONTEXT IS EVERYTHING.
I helped the community computerized our records about 8 years ago. Up until
then we used bound paper ledgers. For historical reasons the ledgers are
invaluable because each page reflects then entire history of a lot/home from
the original plat until today. We have evolved from DBASE, to Peachtree
databases, to Access databases. A computer database is no help to try to
figure out why the sewer line was run through my yard and not on the sewer
easement in 1960. Written notes in the ledger help me to understand that the
rock was in the way and that hand digging was easier through my yard. Now
if you want to know why one house is constructed over the water and not on
shore that is another story. CONTEXT IS EVERYTHING.

The boot sector, PRODOS, and a system program, usually BASIC.SYSTEM.

Well read on. I did say that the existant trapping ports 03/04 (603x and
604x)
that corospond to nominal PDP-8 console are also incomplete and cannot fall
into the interrupt skip chain as a nominal TTY (m-series) module would.
Sure
revised slushware can fix some ills but, not all. Add to that the printer
and COM
ports are using devices that are also off the PDP-8 track. It really ends
up
that despite slushware the hardware is enough odd that standard PDP-8
code (aka OS/8 and programming handbook examples) do not work or
have to be modifed from the source code side like OS/278 was.
Impossible, no. Reasonable, I don't think so. I've played with the 6100
and 6120 enough to know it's just enough different from PDP-8 that it does
make a difference with IO and most peripherals. Still, it's usability and
perfomance as a hybrid is nothing to ignore. For those interested in
programming the PDP-8 like 6120 it's a great platform to see how a
simple machine is anything but.
For my $.02 finding a tube (vr201 or any monochrome monitor) and
a DEC keyboard are not that bug a challenge as they were widely used
on rainbow, pro and terminals. Making the cable used is also not that
hard.
If there was any hack at all that is worth adding it's the real reset button
I have on mine. Saves power cycling.

;) In these days of the PC retrorevionist history of computers who knew?
It's the comma splice, that did it! Because of how you constructed the
sentence, the date, "1928" was juxtaposed between toshiba and
deployment of electricity. I hope my grammer was suitably twisted.
Seriously it really wasn't clear enough that there were two distinct
though realted ideas there.

I just called a local (Fort Worth, Texas) University, asking about surplus
property, and they said that all Texas Universities are required to turn
their old computers over to the Texas Criminal Justice (or something like
that) Department. Has anyone else heard of anything like this, or know why
they have to do this? Does anyone in the Dallas/Fort Worth area know of any
Universities that sell surplus property to the public?

I was aware that Toshiba was building facsimile machines in 1928
in Japan, but I didn't know the ability to send an image to a remote

Hi:
I'm not particularly good at C, so I'm trying to learn more as I add
tape image support to Claus Guiloi's Altair Emulator.
Anyway, I have a "C pointers" question regarding copying the tape
bits to the emulator memory. Here's some pseudo code...
//delcared in i8080.c MEMSIZE is virtual memory size in bytes
uchar Mem [MEMSIZE];
BOOL ReadTape (PSTR pstrFileName)
PSTR pstrBuffer ; //buffer for fread command
// make sure the file exists
//allocate memory to fit tape image length and load file
//determine file type (BIN or HEX)
//if BIN, make sure that the image fits into the emulator memory size
if (iLength > MEMSIZE){
OkMessage (hWnd, "Program too big to fit in memory!", szTitleName) ;
return FALSE;
}
// for binary, so get load address from user and copy to memory array
addr=MsgBox("Enter load address"); //obviously wrong. but it's only pseudo
code
// make sure that (load address + file size) <=65535
// copy binary image to the emulator memory
for (i = 0; i <= iLength; i++)
Mem[i+addr] = (uchar) *pstrBuffer+i;
return 0;
This is the important code. The Altair's memory is represented by an array
of type uchar and pstrBuffer is the file buffer used int he fread command.
My question is whether I'm doing the assignment right?
Thanks again for the help.
Rich
Ok, at least three people have questioned my remark,
so I'd like to restate it. I was going to let it pass,
but here goes.
An article in an old issue of Radio Electronics,
which was a construction article using surplus
equipment, made the remark that fax'es weren't
a new invention (new meaning 50's-60's) but that
Toshiba had built and sold them in Japan since
1928.
I posted this remark as a reply to someone who
said that the facsimile machine had been invented
in the 1700s. I found this difficult to believe
as I would have thought that an electrical infrastructure
would have been a necessary requirement.
I was corrected on this.
For anyone who misread my message and got instead that
I thought electricity had been deployed after 1928
needs to go back to school and learn English all over
again.
Of course, if we were talking about Arkansas, I
do believe the fax machine is older than Arkansas
having electricty.
Any Black Oak fans out there? :-)

The software on Apple's FTP site is all in Mac format (.HQX or MacBin).
Modern Macs have a hard time creating GCR 800K disks (if they can at all).
Apple has gone to the cheaper MFM-only drives which handle the 1.44MB disks
well.
GS/OS v6 (the latest) needs more memory than just the 1MB Apple memory
card. If your IIgs only has about 1MB then do not bother with GS/OS. The
previous owner may have been using them as IIe's (ProDOS 8) as I do with my
IIgs.
I can copy the disks for you, but you will have to send me a box of DS/DD
disks as I do not wish to lose any of my little hoard.

I *think* that ASFS v2 can only run on System 6 while ASFS v3 can run on
System 7. Both may take over the entire machine so using the Mac normally
may be impossible. Make a backup before experimenting!
My answer to the Apple II/Macintosh/MS-DOS data transfer problem is a
Macintosh LC II with an Apple IIe card running System 7.1 and the extension
that lets me read and write Apple II and MS-DOS disks. The extension
cannot handle Win9x long file names but I do no need that.

Granted, this is correct on both counts: the ps needs tested before it's
applied to the system, and the heads probably need to be parked before the
system is moved. If I understand Mr. Davis correctly, he's suggesting that
the ps be tested and possibly repaired or replaced, then the system should be
booted and the heads parked, all before taking the system home.
Try doing this in a surplus store. Hmm, and what happens if the ps is okay
but the system won't come up? Still can't move it until you park those heads
. . .
Personally, I just throw caution to the winds, handle the item as carefully
as possible (it's probably been kicked around for years) and take it home so
I can try to figure out what it is that I'm now the Proud Owner of ;>)

I have a mac plus in my collection that has something called a Hyperdrive installed in it. It's a controller card and MFM hard drive that fits behind the crt and everything actually just fits. Mine amazingly still works. Unless it was a special configuration, there was no such thing as a dual floppy SE with a hard drive.

Hello,
A friend of mine picked up a nice sony 17" (Mac) monitor, and it has the old
style DB15 connector. He wants to use it as a VGA monitor on his PC and I
don't know offhand what the pinouts are, on either end. I can make a quick
adapter to see if it works okay or not for him.
Kind regards

For anyone local (or who can get here relatively easily) and would be
interested in this ....
I stopped by the Goodwill Computer Store over the weekend, and saw that
they have a bunch (maybe two dozen) SPARCstation IPC's and IPX's, for
which they are asking $25.00/each. The people in the store didn't know
anything about their configurations (as they said, "We're pretty clueless
about those boxes"....), so I don't know if they come with any memory or
disk, and I didn't bother trying to open any of them up. Some appear
to have graphics accelerators, though (based on looking at occupied Sbus
slots on the back of the machine). There are also a couple of
SPARCstation 1+ and SPARCstation 2 machines, in about the same price
range, plus a about half a dozen HP/Apollo Series 700 machines for which
they are asking $37.50. None of these machines appear to include any
keyboards or mice. There are a few Sun monitors on the shelf, but they
are being sold separately.
To the best of my knowledge, the store does not ship, so you'd have to
physically visit there to make a purchase. I don't know who you'd talk to
there if you wanted to work out a "special deal" of some kind (e.g.,
purchasing several machines at once, for a lower price), since the
day-to-day store staff do not have the authority to renegotiate prices.

Think of Volta and his electric piles. Electricity generated by moving
wires past magnets was a later development, but there was battery power
in the 18th C.
ISTR the device required an engraved copper plate for sending and synchronized
pendula, one on each end of the transmission. I think the receiving paper was
treated in some way to change color when exposed to an electric current. It
wasn't very efficient, but to be able to transmit an image over a distance at
all was quite a feat for its day. The practical application had to wait until
the development of a national communications infrastructure.
One of my favorite quotes from the telecommunications industry was a fellow
who was chided for his enthusiasm about the new telephones. After all, we
had the telegraph - who really needs to speak person-to-person all that
badly. His (paraphrased) response: "The telephone is a wonderful device. I
think at some point, every city will have one."

It sounds like he's making an interesting video.
I'm sure he'd appreciate any insights from list members.
I haven't checked my archives to see if I have this

Running wps278, no! that software talks to the console at the default
console device addresses.
>Since it's in the PDP-8 family, can it run OS/8?
Yes, specifically OS278 version. Again the tube and keyboard are required.
Why? the default console is devices 03/04 and those ahve been assigned
via hardware to the CRT/keyboard with slushware support. Slushware is
the code loaded into the alternate memory (Control pannel ram) to do
"special tasks".
To run it to say the printer or comm port you have to use OS278 and write
a new console driver and bind the two. To do that you'd need a PDP-8
or a PDP-8 emulator.
>BTW, Does anyone have any stories of favorite PDP-8 or Decmate hacks,

In theory a DECmate could do music... the problem is interfacing it as
there is no "bus" to grab that is easily available. the problem is one of
the fully integrated system and trying to add/interface to it beyond the
available design. It could be done but it would not be easy.
It would be good to go to the PDP-8 FAQ and read the treatise
on why a DECMATE is not a PDP-8, (almost does count!).

Well just got back from my two weeks in Houston and had a few great
finds and a little bad luck. The good news is I found a number of good
finds, here's a short list as some of the items are not 10 years old
yet.
1. Royal TA model F1 computer, ext. floppy drive, and user's manual all
for $6
2. Amiga 1040
3. Percom ext. floppy drive unit
4. 15 - Mac keyboards, no cables but they were free for the taking.
5. Team concepts printer
6. NEC MultiSpin 6X cdrom reader
7. Socrates mousesystem with tablet and mouse
8. Epson Equity LT-286e laptop not working but was also free.
9. Scan-It by digital media labs for the Mac, $8 bucks at flea market
10. Sega 3D adapter
11. Many manuals and books
12. HP 98720A
13. Amiga 1000
14. Suncom animation station computergraphics sensor pad
15. Atrai printer adapter for the 800
The list is much longer but the other items do not meet the 10 year
rule.
The bad news is I found a System/36 model 5362 (complete) for $50 at a
thrift in Houston and I paid the folks for it and asked if I could pick
it up the next day as I would need a truck to carry it. They said ok
and when I came back to pick it up someone had trashed the machine by
taking out 5 cards and breaking them up on the floor next to the unit.
I asked the store manager to adjusted the price I had paid for it but
they said I had purchased it "AS IS" and said it was not trashed when I
purchased it the day before. They did agree to lower the price on a Mac
145B powerbook that I found sitting on the shelf there as a way to
settle my problem. I have never had anything like this happen before.

I'm hoping that someone knows something about some of this stuff and/or
can use some of it. Not free but really reasonable IF you can come to
Roanoke, VA and load it up.
HP 3000 Series III mainframe [a couple of racks worth, but some vandal
hauled ALL the cards to a recycler prior to my finding it]
HP 3000 system 30 cute little R2D2 sized mainframe [no cards]
HP Tape Drives 7970 several variations
HP disk drives, big and heavy 7920's & 25's
HP keyboards & terminals 2640,2645, maybe some 2649's
non HP stuff:
CDC PA5N1 harddrives--also heavy!
Bunch of NCR minis running VRX or VRX/E, also got a couple of
controlers and a PS or two from the same series
pile of TRS-80 series III
Not cheap but lots of them:
HP 1000 E&F series minis
HP 21MX series minis
HP "A" series minis
This is a serious size pile--probably 2-3 tons of stuff in really good
condition. My storage runneth over. Craig

Wow, that *sucks*. Sounds like somebody needs some broken fingers.
Sorry to hear that, man.

Well, thanks to a clever guy on c.s.a2, I got the IIgs to network boot.
It involved going into the Control Panel, setting slot 2 to AppleTalk, and
setting the startup slot to AppleTalk. It magically found Steve, the Mac,
and was able to connect and boot ProDOS 8. BASIC.SYSTEM came up without a
hitch, and I was able to use the Mac as a fileshare without problem. Neat!
Thanks for all the help, folks!
It had some trouble booting GS/OS from the Mac, however. It showed the
"Welcome to the IIgs" box, and got about half-way through (at the bottom,
an AppleTalk share icon eventually showed up), but then abruptly bombed
out and dropped back to the AppleShare client. GS/OS then wouldn't come
up at all until I rebooted the machine. Corrupt copy or not enough memory?
Someone on c.s.a2 said it should at least boot with 1MB, even if it
couldn't run much.
Later today I'm going to build those GS/OS disks and see if starting it
up from the floppy drive makes any difference.
