The 2010 discussion is interesting to me.
I have a SMC 2010B with a date code of 7736 in Ceramic with gold legs. Is
this a second source of the Western Digital or something different?
I also have a couple of similar chips by SMC, a Plastic/gold 2009H with a
date code of 7942D,
and a Plastic/gold 3007-A01 with a date code of 7852A. This one has a P.N. of
27-001 on it also and is a 28 pin dip.
The first two, the 2010 and 2009 are 40 pin dips.
All seem to be limited production run chips as I have not seen others of them.

Cool, typical of many non horizon NS* systems. A bit of this
and that.
Uhm what are you using for keyboard input if the VDM is output?

I did some looking and find nothing that says Lifeboat did 1.3
for NS*. The copy I have is 1.403 for NS*. They may have
done 1.3 but the timeframes for 1.3 and Lifeboat are off.
Sounds like you need more ram. Get another 16k for safety.
A cromemco ram16 or ram17 should be easy enough to find
or other 64k static.

Picked up an Intel brand Pentium 100, runs OS/2 nicely. Also found a DEC MicroVax II with 2 4-line serial controllers. No drives, but I have a few spares. Time to froray into VMS.
Last Sunday I went to see the Woz speak at the Mac Group of Detroit. Fascinating speaker, if anyone has the chance to see him I highly reccomend it. He talked in-depth about working at TI, designing Breakout with Steve Jobs for Atari, and designing his own computers at the Homebrew Computer Club. Most fascinating factoid: He was inspired to make his first TV-display terminal when he paid a visit to Captain Crunch and saw that he had a Teletype in his apartment, and was "Talking to some guys in Boston!" over Arpanet.
Hi,
I have only one diskette that came with a Heathkit H89 computer. It's
a soft-sectored 5 1/4" Dysan 107/1 flavour. I also have a couple
boxes of "newer" 5 1/4" diskettes that i used in the IBM pc world,
which are also soft-sectored, but are double sided, and single or
double density. I am wondering if i can reformat these (in CP/M for
example) and use them in the H89? It makes sense that i should be
able to do this, since they're obviously better quality (ie. can
store more info) than the older SSSD's, but I'm not sure if I can do
this. I would test it, however, at this time, i don't have format.com
for the H89.
Thanks Bob

Ah, you may need more memory for that. The Lifeboat NS* dist for 1.4
needs 4k more, they sorta grafted the NS* dos to the BIOS as disk
drivers so it's a bit fat. I bought the 1.4 copy way back when (it was
new release then).
Assuming its for a NS* Horizon it will be personalized for the default
NS*
IO addresses. HOWEVER... it was also distributed without IO
personalization. You will need NS* dos and one of the monitors or do
it from the front pannel. I know I did that using the first machine
(altair)
before I moved to a real NS* horizon. DOCs for that version are a must
or hope there is a readable example on disk.

Dont bet on this. Read part 15 carefully. depending on the service
and all it may not only be permitted it may be a case of the reciever
(or its owner) has to live or deal with it by adjusting their end of the

The standard distribution sized for memory as:
1.3 16k
1.4 16k
2.0 20k
2.2 20k
This was the expected memeory for the startup of a distribution disk
as it was "sysgened" for that size. It left enough space in all cases
to run sysgen(or movcpm) and leave an images in the available TPA.
The actual memory needed, using the standard SSSD 8" distibution of
2.0/2.2 was 2k for the CCP (when loaded), 3584 byts for the BDOS
and about 1k to 1500bytes for the BIOS. The 1.3 version was only
slightly smaller.

My latest bright idea, an 8x10 net (maybe 10x12) to hang from the garage
ceiling to hold all my big empty boxes, bags of filler, etc. (a good
portion of my garage has a 14' ceiling, so I have a lot of "room" even
above head height. I'm am not entirely sure what one end will be anchored
to, but I am so jazzed at the thought, that most likely I will run out
first thing in the morning and buy and put up the net (anything netlike
should be fine). Lets just say that right now my empty box and foam
collection takes up about one 8x10 rooms worth of my garage and house.

Regarding cargo nets attached to the garage ceiling.
I also thought of the same idea, but an interesting occurrence has made me
cautious. I have several articles attached to my garage ceiling, mainly
sail boat parts and one had a rope release hanging on it. The dangling rope
release wrapped around the front bar on the car-top carrier on my wife's
van, which pulled the article off the ceiling, my wife now has a cracked
windshield on the van. I have now shortened the release and taped all loose
ends together. It also made me worry about some item falling onto the car
if the attachment screws pulled out.
I now worry less because all of the stuff is now above my car!!

Hello Douglas,
The Multics system that was shut down today at Halifax will likely
be available for purchase from Gov't of Canada "Crown Assets" soon.
I should mention that the configuration is, roughly speaking,
3 x Multics CPU. Also, modifications (by Alan Haggett) had it
running as Y2K compatible. ***SYSTEM WILL BE SOLD WITHOUT DISKS***
(due to security considerations). Disks are supposed to be available
through third party suppliers.
Serious inquiries to purchase this system as a workable system
(capable of booting from tape, etc.) will only be useful for
the next few days, as the current plan is to break up the unit
in about 2 weeks, i.e. about 13Nov2000.
The disposal of the system is being coordinated by Mr. Dave Renshaw.
Please contact him for further information as per:

Could someone give me the quick walk through on what it takes to create an
account in VMS 7.2? I used to know this, but it's been a long time.
The steps I remember are:
1. use authorize to add an identifier for the person.
2. use authorize to add the person.
3. create their directory.
4. use authorize to set their password and clear the disuser flag.
5. log in on squeeky clean new account.
The problem is, I have an account on my vaxstation, but either I never
managed to get it to work or I forgot thet password. The security
alerts that come up in audit server tell me my password is bad, even
when I'm typing in what I just used authorize mod jim/password=<whatever>
to set.
Thanks.
And I have to say ELM looks somehow more *right* on a vt220 amber monitor than it does in a window. :)

First of all I'd just like to say a big hello to all the group members. Yes,
I did make it through boot camp, & now I'm up in Groton for sub school.
Anyway, I was wondering if anybody had a working Apple Newton 2100 (or
upgraded 2000) with all of the stuff it came with (dock station, CD, stylus,
manuals, etc.) that they would be willing to let go for cheap. Can you help
me?
Also, if the Newton has the keyboard, I don't want it, but if it has a carry
case, I'll take it.

I have two PC PL/1 compilers and some other from

complete my stuff to begin.

I needed to work with Java from two months from now to
develop one financial application to my job. It offers
all what I need to develop this emulators but specially
to simulate a time-sharing system.
Teorically all the papers about Multics that have now
maybe sufficient to simulate something like the
pagination mechanism. and the virtual memory. The
specifications about the first Multics let me do
a virtual disk from 4 Millions of words of 36 bits.
There is an study about the modules that compounds
the kernel and the recommendations to reduce its size.
I have some source code in PL/1 of some Multics utilities
and a list of 314 commands like appears in
http://www.multicians.org/multics-commands.html ...
I only needs the messages of the commands to simulate them
but logically I should agree the source code :-) And, in
other way, the mechanism of console or terminal session
that Multics used. That's all for now. I prefers at this
instance to made an hipotetical machine that runs the
System before than a real General Electric 635/645. Even
I'm not interested by now in the security mechanism that
were developed later.
Well, that's all for now. Thanks for your kindly answer,
Douglas. Greetings from Spain.

Here's the DEBNT installation from VAX 8200/8300 Installation
Guide. I really remembered that I had the real docs for DEBNT but
I can't find them at the moment, anyway here goes:
4.8 DEBNT INSTALLATION
1. Remove processor cabinet front and rear doors
2. From the rear of the processor cabinet, release the BA32 box
track lock (Figure 2.14).
3. Slide the BA32 box out of the cabinet.
4. Remove the BA32 box top cover.
5. Insert the T1034 module in the VAXBI cardcage.
6. Rotate the BA32 box up and remove the bottom cover.
7. Install the transition header on the backplane if the slot
holding the T1034 module.
8. From the rear of the BA32 box, open the appropriate cable restraint
and feed the transition end of the DEBNT cable into the box. Pull
enough of the cable into the box to feed the cable under and through
the rear brace and up to the backplane of the slot that holds the
T1034 module.
9. Connect the DEBNT cable to zone E (left) of the transition header on
the backplane of the slot that holds the T1034 module.
10. Connect the 12V power cable from the power supply distribution board
to the pigtail connector on the DEBNT cable.
11. Close the cable restraint at the rear of the BA32 box.
NOTE
Route the DEBNT cables separately from the power cables insider the
processor cabinet.
12. Replace the BA32 box bottom cover.
13. Rotate the BA32 box down.
14. Connect the DEBNT cables to the distribution panel.
15. Replace the BA32 box top cover.
16. Power up the system. The DEBNT self-test runs upon power up.
Check that the yellow LED on the T1034 module lights.
If the yellow LED does not light, refer to the DEBNT Ethernet
Tape Controller Technical Manual.
17. Refer to the DEBNT Ethernet Tape Controller Technical Manual for
the complete acceptance procedure.
18. Slide the BA32 box into the processor cabinet.
19. Replace the processor cabinet front and rear doors.

I've got a VAX 6000-410 (complete with everything BUT disk controller and

cluster node) that I picked up a few months ago intending to ressurect
it and play with it occasionally, but a couple of things have stopped me
>from doing that:
1. Hot as hell in the garage in summer in Texas.
2. Cant find the plans to convert from 115V 3phase to 220/240V single
3. No available outlet for it when I *do* find the plans to convert
it. (adding another one turned out to be prohibitively expensive).
4. No time!!!!
Anyway, if anybody on this list within driving distance of Austin, TX would
like a free (well, something in exchange would be nice, smaller VAXen, ham
radio equipment, etc but if nothing lse, come get it and its yours) VAX 6000
system, let me know. You'll need at least a small pickup truck and at least
two people to load it into said truck; its fairly heavy. I'd help, but I'm
still under doctors orders to not lift anything major for another few weeks
(pulled ligaments in my wrists while rackmounting a Sun E450 @ work a couple
weeks ago).
Pictures of the VAX (along with serial #s, card inventory, etc) are up at
http://www.decvax.org/vax6000.
I'm not gonna junk the machine, but someone could be getting more use out
of it right now than I can... so until it finds a better home, its in
the garage.

Seeing the mention of the Shugart QD floppy drive brought to
mind an Altos 586T that I used to have that used this drive, along
with a Wangtek 60MB streaming tape drive. This was an 8086 based
server released around 1983 that ran XENIX and used a number of Z80's
to handle the I/O on both the serial ports and disk subsystem. I no
longer have the machine itself as it was horribly corroded by the
time I got it, though I do have a replacement Wangtek tape drive and
a copy of the XENIX floppy disks for it, as well as two 3M DC300XL/P
data cartridges that supposedly contain a full system backup. Short
of finding another 586T, is there any way of at least checking the
data integrity of these tapes?
thanks and take care

It was the rare and maybe only thing Zilog did right and that was
persuing
the embedded market back around 84-86 timeframe. That was the
breakpoint for PCs taking over and Z80 based systems and their like
starting to loose influence. that and the Z8 business kept them going.
The next big break was the Hitachi licensed 64180 (z180) giving the
embedded designer a MMU, sio, DMA on chip and it was a little
faster.
I see things like that as important to the evolution of the
microprocessor
market and the chips. The same forces would also keep the 6502 in
the running.

Actually the raw Z80 is not seen much in new designs but
it's later fellows are very much there. It's one of the most
commonly available of the old line CPUs.
If the 6800 were still available from Moto (68705 is) it would be
used still as is the 6502 decendants.
Like PDP-8, PDP11, VAX, Nova, 6502, 6800 and many others
a good design is hard to displace.
Oh and the CMOS 8085 also went to mars to push rocks
around very successfully (mars rover).

The TEAC 55F does that natually and the 55GFV jumpers to that mode
easily. The latter was used for DEC RX33, PC 1.2mb and a lot of other
uses so it's pretty easy to find. I have a pot load as it's about the
most versitle drive in the 96tpi class. The mitsubishis are a good
second
choice and also widely used in PCs.

The 55GFV for this use is jumperd so that its running as the 55F and 720k
mode. They are interchageable in this app with one note: the 55GFV
is far more common.

I've been running one that way for several years. The drive I burried
inside
as "A:" is one of those oddball IBM PS/2 no bezel types. By doing that
the externally accessable drives are uncommitted and makes space
available.

And as the plain ole Z80 as well. The embedded systems world is
crazy about it, using it all over the place. I know a guy (younger
fellow, just out of college, only learned what the college decided to
teach him, very naive) who works for a defense contractor...sent me
email the other day asking if I'd see the neat "NEW" processor called
the Z80. What a great embedded processor it is, he babbled. He was
quite pleased that someone finally came out with a really nice cpu that
had an instruction set that made sense for the embedded world to use.
He just hates the PIC and the 8051. (I don't know what his problem is,
I like 'em both a lot)
I explained that I was running a Z80-based general-purpose computer
fifteen years ago (an IMSAI with a CCS Z80 CPU board which I still
have) as my main machine, and that the Z80 processor was a
general-purpose machine that was very popular in the 70s and 80s...and
was definitely nothing "new".
Know what? HE DIDN'T BELIEVE ME!!
So, yes, folks...the Z80 seems to be gearing up for a second
life...this time as an embedded processor. There are many variations
as Allison stated above, but the standard 40-pin dip that we all
built SBCs out of years ago is at the head of the pack.
Scary. But kinda cool in a way.

the best choice is FD55GFV or the FD55E series. I happen to use the GFV.
Before going to 3.5' drives.
Also you need the drive personality board or turborom will not run in
other
than 40 track mode.
If you have trouble finding a suitable set of drives let me know.
I may add that I kept a 360k (DD48tpi) in the system as that is common
media (odd disk finds I'd like to read with uniform).
Also you can use 3.5" floppies (anyone that has jumper or switch for
DS0-3).
Use them with 720k media and it's nice. Another trick is to put a 3.5"
drive
internal and treat it like a hard disk. This is my current config and
that gives
me roughly 1.8mb of space (A:781k, B:360k, C: 781k). One of the CP/M
oddities is once you get drive size orver 500k space as a problem seems
to drop off quickly as an issue.

Ok which version of the SC/MP?
ISP8A500 (PMOS part)
isp8a600 (aka 8060 NMOS)
SC/MPII 807x
(the 8073 was the version with NIBBLE a Tiny BASIC in internal rom)
There were subtle to not so subtle differences. I have two of the three

As if I dont know this? I have an ISBC80/10 and a BLC80204 plus several
Hurikon Multibus boards. It's a task I've done before along with
designing
for multibus. Whats the point? You set up the board to a common config
and with that write a dumb monitor for those addresses. Added t that
code is some diagnostic stuff to blink leds or toggle lines that would
otherwise do nothing to show there is a cpu and some ram operational
if it doesnt talk to the console.

Then you dont have the software manual. My memory of the board was

I know as I loaned out the software manual for my 80/10 years ago and

They never changed it much save for a bug fix or two through the early
80s.
use the monitor for the SBCs either the 8080 or 8085. Intel had the same
basic one they used all over the place.

It does, its a compiler switch. Crummy code though.

It's your pain. I dream in 8080/85/z80 so its no big deal to write a 1k
monitor. It's likely easier now as I have a basic monitor on hand that
ive used for years and could be tweeked for that.
Of course any of the published monitors for 8080 like the LLL AMS80
(KILOBAUD) monitor will do as well. If you have Burskys book
The S100 bus handbook there is a copy of Vector Ones monitor in
there.
A monitor for a a ISBC80xx or BLC80xx is a rather basic thing and
should easily fit in a 2716 (I've done nice ones for 2708!).

I know I have their manuals and 5 or 10 of the NSC8050s (pull EA and

I've not yet found a board-resident monitor for the Intel iSBC 8024
board. I've got a number of these on hand and have used sadly inadequate
resources that worked (barely) for what I've been doing with them, but
would like to make it worthwhile writing a set of test scripts for my
notebook funcitoning as a terminal attached to the iSBC 8024.
Find the manual for that. The code they used it in it. Also they used
the same monitor
in a lot of products with mostly address changes.

Its damn confusing isn't it? Unfortunately the Montegar CD-ROM is a mess
when it comes to kits, some have kits some don't, very sad. Here are some
clues:
You can get a directory of the CD by mounting it and typing:
$ DIR DKAxxx:[000000]
(note that is six zeros)
You can leave off the zeros when you find a directory, ie :
$DIR DKAxxx:[TCPIP_VAX050]
If you find a directory full of savesets (they will be named "foo.A foo.B
foo.C etc") then you can install them with:
$ @SYS$UPDATE:VMSINSTAL foo [directory spec where the save sets are]
So for TCPIP it is
$ @SYS$UPDATE:VMSINSTAL TCPIP_VAX050 DKA400:[TCPIP_VAX050.KIT]
Note that KIT is a subdirectory of TCPIP_VAX050 and you need your CD-ROM's
target not mine :-)
If on the otherhand you find a file that ends with the PCSI extension, then
that is designed to be installed by the PCSI system. You do that using:
$ product install NAME /SRC=[directory]
Note if you don't know what its name should be (and believe me it can be
tough to guess some times) then just type:
$ product install /src=[directory]
And when it asks for a name type * there will be only one choice and it
will be chosen for you.
> Basicly I have navigation troubles.
Yes, there are those "logical" names versus the "real" name of the drives.
Some clues there are :
[000000] is the root directory
[foo] is a file FOO.DIR in the root directory
[foo.bar] is the file BAR.DIR in the FOO directory
Typing
$ SET DEFAULT [directory spec]
Is like doing a "CD to directory"
and typing
$ SET DEFAULT [-]
Is like typing "CD .."

It was part of the NSC SC/MP product line and as such oddball.
The 8154 with a 74374 otherwise worked fine with the 8748
and offered features that only 8255 and 6810 woud supply
in a single 40 pin package.

Eric Smith seems to have summed it up pretty well. I'll just add my
