1) Ok, here are the two things I was considering doing to change the mailing
list settings....
A) Reject posts to the list which contain any kind of HTML content. I think
this would be fairly unobtrusive - most people don't want HTML posts here
anyways. And - I would bet that most all SPAM contains some form of HTML, so
this might not get rid of all SPAM forever, but I think it would make the
very few that come here dwindle to even less. Comments?
B) I also like the 'self-policing' idea of making posts to the list from
non-subscribers get a subject tag of [OL] or something like that. This one I
am not sure how to do off the top of my head, but would think it pretty
straightforward. Comments?
2) WRT the archives at www.classiccmp.org THAT is a project I have fallen
far behind in. When I moved the list from the old ISP to the new ISP (me in
both cases, long story)... something broke in getting emails from the list
to the archive mechanism. I noticed this maybe a month ago, and when I
started digging into it I realized it was time for a change - the archives
there are not searchable and that just isn't acceptable. So - I have been
looking for software to HTML'ize the mailing list that allows searching as
well. I really need suggestions here as my initial searches came up less
than satisfactory. The archives are currently using hypermail. My criteria
is something that is FreeBSD and Sendmail friendly, and allows searching the
archives OR viewing them by thread. I don't mind if the emails need to get
stored in a database, but if they do, mysql must be the database used (picky
aren't I). The only package I found had statements all over it to the effect
that "this package will no longer be supported by the author". I did notice
the list archives for netsaint that are stored at sourceforge look REALLY
nice, and do allow searching, but didn't see a good way to follow threads. I
would greatly appreciate it if anyone can point me to mail list archives
that work well (for the user) and look nice (or to software for unix that
does the same). Please send these suggestions to me off-list at
jwest(a)classiccmp.org
3) This isn't really important - just random "what if" thinking out loud - I
was considering moving the mailing list and mail list archives off to a
separate machine that does nothing but classiccmp. This is being considered
for logistics reasons, not for horsepower/load reasons. I have all the
spare components (cpu, memory, drives, etc) but no spare rackmount chassis.
I can just order a rackmount chassis under my company which I'm perfectly
willing to do, but was wondering if anyone had a rackmount chassis just
laying around that they didn't need and would donate to the cause. The key
criteria - EIA units (space!). I would strongly prefer a 1U (1 EIA unit, or
1.75 inches) tall unit. We charge on rackspace by the inch, so I want the
machine to take as little space as possible so I can obviously sell the
rackspace to other paying customers. I would consider a 2U (2.5 inches) tall
unit (which I already have spare) as a fall-back plan, but definitely
nothing taller than that. Anyone have a spare laying around? If so, please
contact me OFF LIST at jwest(a)classiccmp.org

Does anyone know where there are some archives of Apple's A/UX OS and
some of its software (like AppleShare Server Pro, and Retrospect 2.0Ci).
I just acquired an Apple Workgroup Server 95 (which is actually 9 years
old, so its ALMOST on topic), and since it originally was designed to use
A/UX, I figured it would be a good system to play with it on.
I'm just not sure where to get a copy, so I figured I would start by
asking here, since I know A/UX has been brought up before (heck, maybe I
will get lucky, and one of you has the original software that came with
the WGS 95, and would be willing to send me a copy).

I set up a DEC GIGI yesterday, but I'm not sure I did it right. I
connected the RGB connectors to the monitor and connected the "MONO"
connector to the "Video In" port on the monitor.
When I turn everything on, the GIGI's "Local", "Basic" and "L1" lamps are
on and the screen paints from a solid light blue to a solid brick
red. Then the screen clears, leaving a block cursor flashing at the top
left corner of the screen and the "Online" lamp lit on the GIGI. But I get
no response on the keyboard.
Are there any GIGI owners out there with a tip as to what I'm doing
wrong? Does anyone have any scanned GIGI docs?
Thanks!

I was back in Portland for a few hours and visited a friend who is a
secondary market dealer. He wanted to know what to do with a Sun 3/280 that I
had mentioned to the list earlier and an Alpha 2100 Server he had gotten in.
He also had found a couple of rare HP calculators that I had him searching
for.
Included are the Sun and Alpha, an Alpha 503e Personal Workstation, a
HP9100B, a HP46 Desktop, The DEC InfoServer 150 I mentioned earlier and a
sneak look at one of the "saved" piles
The Alpha Server 2100 I am sure is working but the drives have been pulled,
no sleds either. Came from the Government.
I think the Alpha 503e PW is complete but I only took a picture of it as an
after thought.
The DEC InfoServer 150 looks complete and operational. I have the equipment
to test there but not the time.
I posted the pictures here:
http://hometown.aol.com/innfogra/
The Alpha 503e he is planning on selling on eBay. He also wants top dollar
for the HP Calculators. However I have got him to take offers from the list
first.
He has the ability to ship heavy items. He also does a good job shipping
airport to airport on some heavy systems.
I prefer to be contacted at whoagiii(a)aol.com. Things are getting busy and
there are times I can't read the list for quite a while.

I've seeing some screen jitters on the screen of my Symbolics 3620. The
characters are sort of doubled up and horizontally offset, as if you had
two copies of the same text on a pair of overhead slides, lined them up one
over the other and then moved the top one about a half-character to the
right. Take the whole thing, make it kind of blurry and you have the
effect I see.
Is this a standard sort of monitor problem that is easily fixed by tweaking
some internal pot (I hope!) or is it likely some bigger problem? Does
anyone have any maintenance documentation on this beast or a spare monitor
they don't need?
Thanks!

I was really talking about the bedsheets - I think they'd be a cool part of

serial & parallel interfaces... ;-) so actual greenbar paper isn't ezactly

The only classic machine I can't get to print is my MicroVAX 3100/m38 - and
that's only because I can't get it to talk TCP/IP... :-( <sniff>

You have two small round connectors on the back of the drive. Those are
the power sequence in and out. You usually hooked all (or groups) of RA81
together with the power sequence cables, and the drives started in
sequence. About 10 seconds between each drive. The first drive have a
special plug in the in-socket.

Hi;
Question to you Tek gurus; is the 2230 a true digital scope meaning
that what you see is a digitized signal or is it an analog scope that
has a digital storage function that you turn ON whenever you need to
capture something ?.
Is the 2232 the same in that respect ? .
I remember using one of them years ago at work - I could see a nice
trace of 67 MHz (analog) but I could also use a digital storage function
to capture a 20 kHz event. Now I need one for myself; as for the
digital scopes I've found that the ones I'd accept are those with 2
Gs/sec to be able to see a series of not very repeatable periods at 80
MHz but they are a bit too expensive... .So I need a 100 MHz analog with
digital storage capability at lower freq.
Please respond to my E-mail adress: mdg(a)idirect.com

I'm looking to get rid of my StorageTek 2920 9track tape drive, if anyone
is interested. It *might* need a new head, but probably just needs a
better I/O card than what I had.
PERTEC interface, rack-mountable (actually needs to be racked for it to
sit up correctly), about 150lbs, 120VAC in. It worked for a few tapes I
tried - the problem might actually be in the tapes I was attempting to use
with it.
Would prefer local pickup, but could ship (assuming I can find somewhere
that'll take something this heavy) if paid enough to do it. I'm not
really looking for much money, just 'enuough' for a couple meals or so.
Best offer within 24hrs gets it (or a flip of the coin if I get multiple
offers).

Well, I can't find any buyers for my IBM 3480 units, so I'm starting to
disassemble one of them so I can re-gain some free space and probably sell
off the large chunks of steel. I was wondering - does anyone (Sridhar?)
have any technical docs for the 3480, like a service manual or something
that would tell me the pinouts of things like the display?

Brain rot kept me from remembering how I handled this... I
didn't... well, I have a hardware debugger called DryIce-51
or something like that. You pull your 8051, plug this in,
it has its own 8051, and IIRC it has an assembler built-in.
Handy for debugging interrupt routines, althought it's not
a true ICE, so you can't trace through machine states.
Then again, more brain rot... I had *some* kind of monitor,
because for the DS5000, I found it handier to use it than
to pull the chip and stick in the DryIce.
Found the SIMTEL 8051 stuff, at least what I downloaded.
Wasn't much. But I have a WIC-80 tape labeled to indicate
some more 8051 stuff is on it. The 486 with the Jumbo-250
seems to be dying...

Subject: Wright Punch up for auction
There's a Wright Punch up for auction at www.govliquidation.com.
The Wright Punch is a cool little manual hollerith card keypunch
machine. Someone ought to get it!
It slipped by me -- auction closes at 8 PM eastern time, that's
less than an hour from now. Sealed Bid sale, $35 min. The
downside is you have to pick it up in Norfolk, VA next week, and
take a big pile of other junk along with it. You'll need a
pickup.
If you're interested it's event 623, lot 46, item 37.

Did it come with the OS installed or did you do it?
You could just re-install to get DECwindows.
Without DECwindows you cannot do full-screen editing
on the monitor - it's just a dumb glass tty.
Your options appear to be:
1) flip S3 and hook up a VT to the printer port
and use it as an alternate console
2) log in over the network (telnet or SET HOST)
3) Install DECwindows
4) Use EDT in line mode or use TECO
(4) would be an education, but perhaps not ideal :-)
(3) is the way to go.
(2) you should do ... all VAXes have the right to be networked.

Yeh-- The 'XV' used the ST-419. Fifteen meg, *very* hard to get.
An RD-52 can be used in it's place, although you can only use
15mb of it.

Well, as I've not found anyone willing to come and get a 3480 tape drive
unit from me, I've taken one apart and am planning on selling the 'useful'
bits from it. I still have two drive units completely un-touched, so if
you're interested in them, drop me a line. I'm not looking to get much
money, just enough to cover what I paid for it.
So far, I have available:
2x 3480 Tape drives.. the actual 'drive' taken out of the unit.
1x 3480 drive unit power supply
1x 3480 drive 'air pump' motor + filter + air tubing..
a 1/3HP, 250VAC motor with an 'air pump' assembly on it, along with
the IBM air filter assembly and whatever teflon (?) clear tubing
that came out of the drive unit.
1x 3480 tape drive unit 'display' that has the main 'user-controls' for
the drive on it.
1x 3480 A22 tape controller 'logic boards unit'.... the set of logic
boards, backplane, and cable from the 3480's controller. Bunches
of custom IBM chips and weird-ass cables (don't know the real name,
look like a 16pin(?) DIP socket stuck on one of those plastic with
metal traces ribbon-cables.
2x 3480 B22 tape drive units, complete.
If I don't get any responses, I plan to (attempt) to get rid of the drives
on eBay, disassemble the power supplies for parts, try and sell the motors
to industrial suplus dealers, and save the displays for who-knows-what.
Try and contact me ASAP, if there's interest I can hold onto something for
a while if need-be.

If you don't mind translating a not too-terribly-long
program for another processor, then I believe MIKBUG
for the 6800 may do ok. My first embedded
systems project was a 6800, and I included MIKBUG in
the ROM so that I could precisely what you want to
do.
The 8051 being a more generous chip register-wise,
translating it shouldn't be difficult.
You can find at least one version here:
http://www.swtpc.com/mholley/MP_A/mikbug.txt
Looks like a fun weekend project.

Hi Everyone,
Now that I have switched to my "newer" system with the
box that holds TEN 5 1/4" hard drives, I am thinking
of some house keeping on the files I maintain.
One very large mess is the set of classiccmp posts that I have
some interest in. I would like to group them, but have not
decided on sub-sets as yet. I am thinking of the following:
Classiccmp General
Classiccmp List (this post will go here)
Classiccmp Technical
Classiccmp Spam (including comments on spam)
Has anyone else set up their own sub-sets? I guess I could try
these out and see how they work, but I though I would ask for
suggestions?
Sincerely yours,
Jerome Fine

4118 is the same pinout as a 2716 except that pin 21 is the /WR line
instead of Vpp, and pin 19 is NC instead of A10. It's a genuine static
part, 1K x 8. A 6116 is similar, but 2K x 8, with A10 on pin 19. There
are also low-power CMOS versions of the 6116. Zilog made a "quasi-static
RAM" 4K x 8, called Z8132, but it's 28-pin. They also, confusingly, made
16-pin dynamic RAMs 8K x 1 and 16K x 1 called Z6115 and Z6116, similar to
the more common 4116 DRAM.

Wasn't there some mention of these things a few weeks ago? Was
somebody looking for one? I seem to have a couple. It's a flip-over
MCA/ISA adapter.
Speaking of PS/2s and 3270s, did Sridhar permanently toast himself?

No, no, I meant a ZX81 doesn't have one built in. Of course we use the
Z80A-SIO (and -PIO). Modems were also commercially produced in the
mid-eighties which allowed a simple mod so they could also be used as
serial ports.

It's been done any number of ways.

Not necessarily. A soldered connection is generally more reliable than a
socketed one. For that reason, many manufacturers solder most parts,
unless they contain firmware that might need changed, or are custom parts
subject to revision (PALs, ULAs, etc).

Well, I was hoping I would get lucky with this one, since it's
more like a scientific calculator than a computer. It's a
very long (for a calculator) dot matrix lcd. One single line,

The power sequencing jumper is a small round plug with four pins that are
placed in a contact near the black data cables. I can't quite picture the
RA81 now, but I think one of the connectors is to the left of the data
cables and one on to the right of them. They should be labeled "in" and
"out". The power sequencing forms a chain through the use of power
sequencing cables such that the first drive in the chain (the one with the
jumper instead of a cable on "in") starts first, then the next one and so
on.
The jumper is about 5cm long, 1cm in diamater I think, usually black with
a silvery threaded ring that holds it in position.

Perhaps I can make up by offering a pointer

This includes a description of the LK250 in Chapter 8.
The LK201 is described in some detail in

(see Appendix B for the LK201 and Appendix C for the Mouse)
which is available at the same location.
It is also described in the PC100 Technical Reference

The correct way to do someting like this in a cron entry is to check the
return code from the cd command, and only execute the rest of the command
if the cd succeeds, eg
(cd /usr/preserve && find . -mtime +7 -a -exec rm -f {} \;)

This one *is* easy: the holder must be spring-loaded. As the amount of

I am trying to get a KFQSA to work with 2.11BSD on a pdp-11. It always
fails with an error in the SA register during the transition between
STEP 3 and STEP 4 of the initialization sequence.
The SA register ends up with the value 101513. The error bit is set and
I think that the rest is an error code. I can't find a reference to
describe these error codes.
An RQDX3 and a CQD-223 in the same machine initialize fine. The KFQSA
initializes in an MVIII using NetBSD 1.5.
I have looked over the initialization code from NetBSD, Ultrix-32,
4.4BSD, Ultrix-11, and 2.11BSD. The values being sent, are all very
similar. One difference is that the VAXen OS use polling during the
init, and the pdp-11 code uses interrupts.
Any suggestions or comments about the MSCP 4 step init and how it works
on the KFQSA?
A pointer to error code reference would be great too.

There's a Wright Punch up for auction at www.govliquidation.com.
The Wright Punch is a cool little manual hollerith card keypunch

It slipped by me -- auction closes at 8 PM eastern time, that's
less than an hour from now. Sealed Bid sale, $35 min. The
downside is you have to pick it up in Norfolk, VA next week, and
take a big pile of other junk along with it. You'll need a
pickup.

In this case, that would do as well. I was just illustrating that you have
to be careful with unattended operations, and not do anything dangerous
unless you're sure you're in the right place (or other prerequisites have
been met).

I don't have either the service manual or my ZX81 handy, so I can't check,
but as far as I remember, just remove the 4118 and replace with a 6116.
There might be a wire link to change (if so, it's obvious) but I don't
remember having to do that. It is good practice to fit a socket, though.
A few ZX81's had a pair of 2114's instead of the normal 4118, which were
in short supply at one time, but the same principle applies (the PCB is the
same).

It's a plain PDT11/150, as a MINC it's useless as there are none of the
usual
lab IO items that made the larger QBUS ones useful. One exception is if
your systems talk via serial IO then it was a pretty useful box.
Now the PDT11/130 (same thing with TU58 instead of RX01 similar) could
be used the same way... I think not.

I've just been shown a load of HP 3000 and HP 1000 gear which
is about to be thrown out, located in Bristol (UK). This
list is approximately what's available:
HP 3000 Series II
7970 B Digital Tape Unit
7970 E Digital Tape Unit
Metier 50 Megabyte Data Storage Unit (disk)
HP 3000 Series III
97935 top loading disk drive
7970 E Digital Tape Unit
HP 1000 E-series computer "Artemis System"
12979 B I/O Extender
7906 Disk Drive
13037 Disk Controller
2648 A Graphics Terminal
2631 B Line Printer
unknown modem
2392 Terminal (qty 3)
Flexible disk drive for HP desktop calculator (qty 2)
Falco Terminal
91148 Floppy Disk Drive
Alignment packs for HP 7905/7906 disk drives
They want to clear out the storage space quite soon, and if
anybody wants any of it, we'll have to arrange something quite
quickly. Most of the computers are in 19-inch racks of about
5-foot (1.8metre) height, but some of them are double-width
racks. Basically, you'll need a van to move them!
Any takers?

I grabbed this yesterday at goodwill. It looks like an
HP-IB/floppy-IDE interface, but I can't find any references.
HP model appears to be:
09L Rev C
09153-66511
or
2815
or
0TF0C07
or
RSWKC3
The card has a bulkhead plate w/ HP-IB connector, address dial switch
0-9, and configuration dial switch 0-9.
PCB itself is about 10" by 3" with a 1.5" by 3" cutout. There is a
34-pin male and a 40-pin male header and dip switches:
TEST <--> NORM
B <--> C
30/40 <--> 10/20
BOTH <
10/30 <--> 20/40
NO FLOPPY <--> FLOPPY

Nope, It's an LSI-11/02 Qbus machine woith a small cage and rack
and RX01(maybe an 02). You need Qbus for the varions analog IO
and digitial IO cards.

The PDT11/150 has no user bus and the oly IO is serial. It is however
the same LSI-11 chip set but no provision for the EIS/FIS. Yes, I know
you can piggy back one of the microms to do that but the board only
has 4 40 pin sockets that are filled where the LSI-11/03 Qbus board has 5.

No, it doesn't even have a serial port (yuk yuk).
If you'd like to turn your favorite 486 into a ZX81 there are ZX81
emulators for Linux, but to my knowledge no one has even entertained the
idea of doing some flavor of Unix on ZX81 hardware.

After considering this, I think you've hit the nail on the head, Joe,
except that the only thing we don't change is the engine! The Z80, ROM and
ULA *have* to be present!
Our goals seem to be:
1 -- Build an interface for every device under the sun, including the
toilet seat.
2 -- Write software to perform every task ever performed by any computer
anywhere. The software should be 100% Z80 machine code and should push the
ZX81 as hard as possible.
3 -- Do all of the above for US $25 or less.
I hope everyone has as much fun with their old computers as I have with
mine!

DEC's destruction began when DEC was palmerized into a ghost of it's
former self and sold into slavery to Microsoft. Then much damage to
this once great computer company, DEC, was done by Compaq (a wannabe
computer company that never made real computers, and destroyed an
acquisition, DEC, that did), and, now, this appears to be little more
than the nails being hammered into the coffin of what was once Digital
Equipment Corporation.

Hi there,
I've recently acquired a set of SGI dials and buttons. These are two units:
The dialbox has SGI P/N 9980992 and is manufactured by Danaher Controls with
Model # DLS80-1022. The buttonbox has SGI P/N 9980991 and is manufactured by
Advanced Input Devices with Model # CMN B018B.
I have not received any cabling with the units and also I have no power
supply. Using google, I could not find any useful information on how these
units are expected to be supplied with power. There are some references to
SGI boxes which provide for power supply on some serial ports, but these where
pretty unspecific and did not reference these exact models.
Does anyone reading this have a set of these and can help me with getting the
pinout and the expected voltages for the power supply for these units?
Thanks in advance,
Hans

Ok, I'll agree that it can and does, since I am
unfortunately forced to use it by corporate edict. :(
I will argue that it's not "easy" to turn off. "Easy"
would be a button that says "don't ever post a message
with HTML." There is no such option. It must be turned
off as a default, and then still on a per message basis
every time you don't want to respond to somebody who's
used HTML with another HTML message.
So I will agree completely with you if you will replace
"easy" with "cumbersome at best."

It's my opinion that Compaq will be pissed away by HP just as Compaq pissed
away DEC.
I never really did *love* Compaq, mainly because they are a PC company.
They make good PC's, but I hate PC's.
The real problem is that several thousand employees are going to get the
axe because of a power trip by an HP CEO.
I love to see someone who actually believes that the "new" HP will compete
with IBM.

Yes, it could. Shame the CPU was idle or doing just the block move.
I've seen Qbus systems (PDP-11) sustain levels like that but, the
CPU was useful.
PCs, and their busses didn't allow for concurrentcy of operations

Ultrix was not nearly as well developed as VMS for multiple CPU
and cluster configs. Available user performance on a 6k system
with decent disks was very high under VMS but under ultrix is
was a less appealing system. I'd used an identical pair while at
DEC with both ultrix and VMS and the ultrix system was a bit doggy
even at lighter user loads (no one liked it).
Comparing it to a 486... no contest with a pot load of users. the
i486 does not have the system robustness and IO capability.

While we're on the subject, I do think the [OL] idea is a good one,
but I just wanted to add my tuppence worth on the subject...
The address I post from isn't always the same as the one I read it from;
I tend to choose the address to post from (work or home) as appropriate
to the content of the message... If we go with the tagging off-list
posts, it would be nice if there was a way of registering additional
'posting addresses' as well as the subscription address.
Not essential, of course, but would be handy (would be more
essential if we got to the stage of actively blocking off-list posts.)
Incidentally, I'm all in favour of the blocking HTML, by the way...
Cheers,
Tim.

Tim Walls at home in Croydon - Reply to tim(a)snowgoons.fsnet.co.uk
It is very contemplative to sit in the basement, room filled with
big iron and lots of blower and disk noise, and watch the system
creep ahead compiling stuff. I remember those old days back in, say,
1994 when I sat there on a i486/33 watching GCC compile (and those
*endless* runs of all the fix-include stuff.) What surprizes me is
that the feeling on a 1989 vintage 6-processor million-dollar VAX
isn't very different! I expected it to be faster with that.
So I looked at statistics. Nothing paged out (0.5 GB of RAM),
but looks like the system is heavily I/O bound and I/O
is quite slow. I even distributed disk load over 3 RA90, though all on
the same controller, but at least that's a KDM70, directly on the XMI
bus. Still, disk access seems just a bit on the slow side. Why?
All terminal I/O went through the Ethernet, which I thought was a
DEBNT but is reported to me as a DEBNA. Anyway, that's just the
few lines of text that are being logged as make creeps forward with
its job.
Looked at cpustat (we're on Ultrix 4.5 BTW), where you can see the
load on the CPUs. Sorry, no "screenshot" here, but in short it lists
6 CPU's and the load on each. 5 of them tend to be 97% idle and CPU#1
is 75% idle. CPU #1 gets bombarded with all interrupt requests while
the others get none of that. Unfortunately I couldn't figure out how
one can see process to CPU allocation. I suppose that each process
runs in a single thread on one CPU every time it is active. Since the
making and the cc-ing is a sequential thing writing temporary files
to disk, I suppose that the 5 idle processors have nothing to do
while CPU#1 takes all the burden of the compiling task plus all
other system interrupts (essentiall all I/O.) So, that's kind of
not optimal.
I suppose, once I have my first GCC built I should use the -pipe
option to avoid temporary files with the hope that the two ends
of each pipe would then be allocated to two different CPUs. That
should then speed up the process a lot, basically could stream cpp
on CPU#1 to cc1 on CPU#2 to as on CPU#3 right through. I hope. That
is, if UNIX domain sockets (i.e. pipes) are implemented so as to not
require any hardware IO. I *hope* this is simply done by CPU#1
entering kernel with an mbuf and CPU#2 entering kernel shortly
thereafter reading that mbuf, so only memory should be involved.
It's interesting. At some time soon, may be early this summer,
I'll give a VAX party where one of the highlights will be a
race between my i486/33 and the 6460 in compiling something,
there we can see if it's really just my perception that the
6460 is kind of slow for the price, even measured by past
standards.
Another thing that made me wonder is that writing to the TU81+
on KLESI-B showed its signs of I/O bottlenecks. When I just
did
# tar cvb 20 -f /dev/nrmt0h /usr5/gcc-2.7.2
the tape would write block by block in staccato and would not
stream. The TU81 is still nice even in block mode, not that
endless back and forth of the TK50 or any other cassette media
that I have seen operating, it's a fast staccato tatatatatatata,
you gotta see this!
Only if I used my dd buffering trick with
# tar cvb 20 -f - /usr5/gcc-2.7.2 |dd ibs=2048000 of=/dev/nrmt0h obs=10240
would it stream over larger sections. But the slightest disk
read activity would cause a little pause to the tape transport.
First I thought I should be rearranging my cards on the VAXBI
busses, but then I remembered that the disks are on XMI directly.
So, a simple RA90 read through KDM70 on XML is just not fast
enough in order to keep the VAXBI - KLESIB - TU81+ streaming.
Are the RA90 disks so slow? Or may be it is Ultrix' bad way of
using the multipe CPUs again, i.e., they still handle all the
work through one single CPU#1 while the others are chatting idly?
Does NetBSD do a better job with SMP? Would it use one CPU for
the disk IO and another CPU for the KLESI-B IO with shared
memory buffers in the middle? May be not if I used just one
process to both read from disk and write to tape (like tar
only), but with the pipe, tar | dd it should do it and that
should allow me to use a smaller ibs for dd, AND have real
streaming write to the tape. Or is SMP on NetBSD/VAX still a
sub-optimal hack?
When I attended BSDcon 2002 in San Francisco few weeks ago,
it seemed like all the BSDs would go different ways about SMP.
I liked what Jason announced about NetBSD, like IO being
handled without memory data copies, and the kernel actually
shrinking in size. I would hope that all BSD/SMP efforts
nowadays seek to allow true load sharing between the CPUs
and not shedule IRQs to only one and not hog that one primary
I/O CPU with *all* processes that have any I/O to do. And
I sure hope that it will be natural for pipelined processes
to operate on different CPUs. Right?

-Gunther
