Jack,
Yes, two things that I'd be checking
1) Make sure all drives are assigned a different number
2) Make sure you have termination somewhere.

Depending on the OS there are commands to display the scsi devices
attached, as the OS sees them.

Re: New TestFDC Results Registry

[william degnan via cctalk]

Please, call me Bill :-)
I have a system with a Catweasel and a connection to the motherboard,  I am
unsure how I have it set up as it has been many years since I opened the
box.I have to see what I am doing in there.  It's a dual-boot system
that goes into either Win 2000 or DOS 6.22, but I forget how the catweasel
is hooked up and wither I use it with image disk or not.

At this point I see the scrolling bars of a synch issue.  I can drop using
STOP A to the OK prompt (even though I can't actually see it) and run the
boot command from the keyboard confirming that I can at least use the
keyboard now and initiate a reboot without serial terminal.  So my machine
is probably getting closer to what I wanted even if so far I don't have the
correct display / cable combo installed.  I have a lot of displays and
13W3/4 wire/VGA converter cables/etc to mess around with so sooner or later
I will get one.

Getting Sun Sparcstation 10 to recognize its graphics card

[william degnan via cctalk]

Working from this page to configure my sparcstation 10 after NVRAM
replacement:
http://www.obsolyte.com/sunFAQ/faq_nvram.html

...but curious is there an installation manual or whatever specific to the
video card in my system, a TurboXGX with STP3010GPA chip
http://vintagecomputer.net/sun/SparcStation-10/Sun_STP3010PGA_TURBOXGX.jpg

I have Solaris 4 installed.  I am guessing around trying different things.
With help I have the OS installed but so far I can't get the system to
recognize the video card and Sun keyboard.  With these installed it freezes
the system...so, I am using a serial terminal to interact with the system.
The video display I have is an SGI GDM-20D11

Eventually I'll poke through to the solution, this is my first Sun box, up
to this point they were "too new" but I'd like to learn how to perform a
system install.

If I find the answers I am looking for I'll post here.

I think given the IBM-esque printed markings all types of IBM core should
be ruled out first.  For example the IBM 1620.  But now you can see why I
am asking, what I have does not quite fit.

wired together.The ...'s represent "the continuation of wirewrap rows"

You can simply boot with thr commanf

@ DL2

PDPGUI is a great tool to build actual disks from a simh rl02 image.  This
way you can test first, get it working, then transfer via m7856 and m9312.

Yes but if it's on and when you power up the system no @ sign appears at
the terminal that says it's not autostarting the console.  At least knowing
what to expect (off or on) is what's important.

As I said, the 11/04 has specific wire jumper settings.  Such as W8.  These
must be correct for the CPU, the UNIBUS must be in a non DC LO AC LO, etc.
I went through all this with my 11/40 (not 04) and it was a great way to
learn about and diagnose the machine function.

Re: 11/04 Project

[william degnan via cctalk]

I am confused by the flow of this thread on my phone but.there are
important things to confirm
1) the console rom does not go in any of the 4 bootstrap slots, these
should be empty for now.  There is a special console rom slot. Please
confirm you have it installed.
2) 164020 should bring up the @ prompt or the 11/04 equiv.  Load thus unto
memory and run from there if you want to load manually
3) the 9312 jumpers (not talking about switches) must be set for an 11/04.
They differ for various machines.  Where did this 9312 come from?
4) confirm you don't have a DC LO AC LO failure.
5) the jumper switches more so pertain to the device bootstrap selection
not the console.  It's confusing because they refer to the console being
on/off in relation to the device to be bootstrapped, ignore all that.
6) possibly the only switch to worry about now is the power on auto jump to
console switch. If that's on when the machine powers up it should cause the
machine to  jump to the console and print a @ prompt to the termunal
assuming everything else is right.

Mark,

If this is an issue about reviving bad eproms?  I assume you have tried the
regular stuff.

What process are you using now to erase 2708/16's?  I have a simple eraser
unit and it seems to always work.  Some eproms go bad but I never have
issues with erasing them.  My point is that maybe you need a better prom
eraser unit.  I would avoid baking them until you have exhausted other
options.  Not sure what others think.  This topic has come up before here,
about putting them outside and all that.  The erasers are all over ebay,
and the hardware store is full of the correct types of lighting, why not
make a box that will do the job?I assume there is more to it that
simply erasing them.

Here's one more... if possible find a working 11/34 and perform a
diagnostic procedure or measurement there and take notes, then repeat on
your system.  That, and swapping known-working boards when available will
help pinpoint problems where they exist.

For an 11/34A can one test for DC LO / AC LO?  If so and you don't get the
correct reading that's a show stopper right there.  Remove all but the
essential cards, terminate the UNIBUS to the shortest poss. size and least
RAM.  I no longer have an 11/34A but there are a lot of similarities to the
11/40.  Many cards interchangable.

Writeup on Preventing Third-party SMTP Relay MULTINET

[william degnan via cctalk]

If anyone is interested, I documented a fairly easy way to prevent third
party SMTP relaying with MULTINET 4.1 on a VMS 5 MicroVAX.

http://vintagecomputer.net/browse_thread.cfm?id=708

I did cheat a little...I set up an email alias on my modern mail server to
forward messages to a single email address on the VAX.  This was necessary
because otherwise I'd have to have added the mail host ID of every mail
server permitted to send email to users on the VAX.  Also, I will have to
create an alias on the modern mail server for every VAX user who wanted to
get mail.

I agree ultimately that MULTINET email is too limited, but for my purposes
I am satisfied.  It's just for the learning experience.

Peter,
Thanks I think this is what I need, just disable smtp within MULTINET.  As
I said in my OP I prefer a VMS or MULTINET solution free of modern hardware
if possible, now that I know what is possible.I was curious to learn
what others did back in the day.

I have a script I run to clear the queue, but that's a pain and it lets
some relaying through.

Preventing VAX running VMS / Multinet from being used as SMTP relay

[william degnan via cctalk]

I have a microvax set up with VMS 5, running MULTINET (and decnet
locally).   The server has a FQDN and after a while being exposed to the
WWW someone out there started using the server as an SMTP relay.  I can
disable and clear the queue, but I'd like to block entirely this from
happening in the first place.  I'd like to learn more about how this
happens in VMS.

Anyone have had this same problem before?  I realize back when VMS 5 was
current it was not so much of an issue, but today it is.  I am working on a
solution.  I can envision a few ways including blocking the smtp relay port
from the firewall, but if possible I'd like to set up a VMS Multinet
solution as a learning exercise.

I am open to suggestions, and once I find the solution I'll post it.

I understand that this kind of thing is not cookie cutter, there are
different levels one could address something like this.  I have a comcast
business router, and one of the 5 IPs I have is NAT assigned to the
internal 10.1.10 port of the microvax.

This is the same machine I wrote about previously as with then, thanks for
your help.  I find the best way to learn is on the actual hardware warts
and all.

I checked and I have a Diconix 150 (not plus).  I took photos of it should
that be of use to you.   I took a picture of the switches as they are on my
unit, assuming this is the "normal operations" setting for a USA IBM
emulating printer, if that's what you're looking for.  There are 9 posts, 6
is up the rest are down.  Mine is a parallel printer (you can tell by the
port on the side not the dip switches)

http://vintagecomputer.net/kodak/diconix-150/

Also IF and this is a conditional IF, the 150 plus is only "plus" in some
other way other than switches here is the non-plus 150 switches' meanings:

ftp://csiph.com/incoming/jim/TSSPRT/acroread/tssfact/tfsprt/kodak/di150.pdf
(I posted a copy to my site as well)

The last three switches pertain to the country.  USA is all down.  6 up
means IBM emulation.

Thanks for the tip about the HP 51604A as a replacement cartridge.  Not
sure if it will work on the 150 non-plus but it's a clue.

Agreed, but just from what I had worked with it looks like it was from an
11/05 or possibly it was an expansion core memory box.  Either way, you
could use it for many things not just an 11/05.   The "stock" 11/05 NC
would have had a different box.  It would have to have been for an 11/05 S
model.

Almost PDP 11/05 on Ebay

[william degnan via cctalk]

This looks to me like the power supply and backplane of a PDP 11/05, looks
to be in nice shape.  Surprised no one grabbed this yet, esp someone with
an 11/05 that has issues with power supply.  Someone might have the missing
parts.

Re: Almost PDP 11/05 on Ebay

[william degnan via cctalk]

I agree with Josh upon closer inspection that the backplane may not be for
an 11/05 I'd have to look it up.  If so, you'd need a CPU backplane too.
The power supply is part of the BA11-KE, at least you'd have that.

PC-Letter "WUI" War over User Interface 1-1988

[william degnan via cctalk]

Here is an interesting article from early 1988 (probably written in min
1987) that compares and contrasts GUIs of the day.  Interesting that they
do not mention OS/2 by name, by this point it would have been available,
given I used it in Jan 1987 when I was working at IBM.  Also the XEROX
interface was not yet dead as the author makes it seem.  If anyone used
Page Maker on a 1987/88 Xerox machine and compared that with "Windows OS/2"
machine trying to run the Page Maker on a PS/2 80 you'd probably agree.

Basically I am unsure what planet the author was from, but you can decide
for yourself.  Talks a little about HP's GUI product, Sun/AT, Apple
Finder, etc.  Mentions NeXT is coming, Commodore is dead, ... opinionated.

I have played around with that problem.  If you have a converter to get
into a VGA port a newer high-end vga display will be able to adjust, but
not a cheap one.  Because I use my vice vga/digital display for mode stuff,
I use a huge SGI color display for all of my 3w3 outputting systems and I
just switch the cable around.  If you could imagine 5 or 6 systems
clustered around the one display.

I am sure someone here has a technical explanation, but in a nutshell the
3W3 world signal isn't the same as a standard vga and cheap vga displays
can't handle the refresh rate.  Someone will prob. refine my answer but
that's why you can't just stick an adapter on there.

Re: Details about IBM's early 'scientific' computers

Following top post of this reply...

There is a doc called 709-7090 General Information Manual D22-6508, which I
don't see in bitsavers (I don't have).  The operator's guide for 7090 Data
Processing System is A22-6535 is on bitsavers, but that's not going to help
you much.  The big hole in the bitsavers collection for the 709-7090 is
A22-6503, the 709-7090 Data Processing System Reference Manual.  It's kind
of like Gordon Bell's book with a combination of hardware and programming
to explain how the system works.  I think that's what you want.

Maybe someone has a copy of this?  If not I can scan mine.  My 7090 is out
for repairs anyway so I don't need it at the moment. Those repair guys
don't move as fast as they used to.

Most of the rest of the docs I have related to 709-7090 are Fortran related.

On the back pages of the 709/7090 Data Processing System Bulletins you'll
find a bibliography of all 709-7090 publications and their titles.

ModComp II on Ebay

[william degnan via cctalk]

Ebay item 272914490265

This is a ModComp IIC I think.  It's all broken up in parts and half
assembled.

I don't think new it was barely $18,000 though, but some day, maybe the
seller will give up and put up a realistic price.  Who knows what's in it
exactly but generally it looks like a communications model with a 7 or 9
track tape unit.  The point of ModComp was to build custom systems but if
the info on this system does not exist on BitSavers, let me know and I will
scan some docs.  I have info on the part numbers from the photos.

The ModComp docs talk about IBM system emulation vs. DEC, so think along
those lines more so, this is *not* a DataGeneral / DEC me-too despite
looking a little like a PDP 8i

At that point, for the time it takes the drive to be ready from a load
should be about 15 seconds.For you the Fault light comes on instead.
If I turn on my drives but leave the computer (11/40) off, the fault light
comes on immediately.  If I then turn on the computer the fault light will
turn off, although I may have to press load first and if so it will turn
off after a few seconds.It's independent of the LOAD/READY lights

based on this informal comparison I'd venture you have a drive issue.  I am
not 100% sure what your termination situation is.  I have two drives, one
terminated but it's with a DEC terminator on the bottom port of drive 1.
The cable comes from the computer into drive 0.  I have a cable going from
drive 0 port 1 to drive 1 port 1.

RK06 Data Cartridges / Alignment Cart Available (and other stuff)

[william degnan via cctalk]

My last email was unclear...I have a few RK06 Data Cartridges and an
Alignment Cart Available. Contact me privately if you have an RK06 drive
and you're looking for carts.  They look like RL02's maybe a hair thinner.
 I paid a small amt, and I am looking to be reimbursed for the cost.

I have no RK06 drive.  RK06 cartridges are NOT compatible with RK07's
according to the manual.  If you're in the Landenberg, PA area stop by,

At some point I will publish a list of other DEC items I have in clean
organized storage.

I don't think there is one.  The PDP 8i is the closest thing but there are
I think 26 switches at the bottom the 8i, I think only 18 at the bottom of
the straight 8.  They thus can't be the same exactly but it may be that the
straight 8 is the same as the 8i, if you use only switches that appear on
both systems (no step counter on the straight 8).  Dave G will know.

I think OS/8 is pretty good for a one user system, if that's what you're
using it for.  You already kind of know it and one can run a lot of
languages on it.  I'd agree about the 11/70, but only if you're running the
kinds of applications found on the disk images that are out there.
Otherwise over time you can make your own tapes/RL02/RK05.etc disk pack
sets (or whatever) to emulate in.

I have a Next Thing CHIP with as many SimH builds and images as I could
find and test to set up, DEC included, so I can switch around at will.  I
have my a serial terminal for I/O.  Certainly never get bored with that
kind of setup.

You might try searching for tc1084/ tc1085.  The 1801 cpu chips' original
silkscreen names were not "1801"

Just before the Tutor RCA sold the COSMAC Microkit and it had the earlier
version of the 1801 chip set:

http://www.vintagecomputer.net/browse_thread.cfm?id=511

Another place to check is auto computers and embedded stuff ... Some if the
very earlist auto computers had 1802s for sure, maybe some had 1801s.  Dual
cpu chip 1801s were not prototypes, they were sold for a good year before
being replaced by the single cpu 1802.

DECmate disks

[william degnan via cctalk]

Anyone have spare OS/8 for DECmate disks, RX02?   (copies originals does
not matter).

I have a lot of RX01 disks, not sure if I have any RX02's, but I'd offer to
trade what I can or pay a fair price.  I may need a VT278 to the pedestal
drive cable.  I have a candidate cable that may work, but it's hacked up
(split) and may not from a DECmate, just found in in the DEC cable bin.
Not sure how rare the disks and/or cable are.  I also need a CPU card RAM
module if anyone has one.  The VT278 appears to work ok without the last
RAM pod/module in the back of the CPU card, but eventually I'll probably
want a full 32K.  It may be required for DECmate OS/8.

I realize It may be possible to make disks, working on that.  I know that
RX02 is a format difficult to reproduce without effort, so I assume the
shortest path is to find someone with a working DECmate, RX02 disks, and
willingness to make a copy using the native system.  I would be happy to
pay a fair price or trade stuff.   I don't have a RX02 drive controller
card other than the DECmate CPU card, otherwise I'd make the disks myself.
I may be able to make a disk using imagedisk, looking into that, but I have
read that this is not easy.  I have more to research on the subject.

Here are some photos of the DECmate I am working on.

Alternative approachhave an open house and invite friends of the hobby
to take an item after explaining why they want it, spread it around a
little, then after all that is done, let someone with no strings attached
take the rest, maybe pay you a token amount.  This way you're putting the
items that mean someone to you personally in the hands of persons you know
specialize in x/y/z.  Anyone who is tasked with taking everything will be
able to hold it forever any more than you, so they'll have to sell/give

I'd double check that.   I have found, at least in my experience, that the
beige are more plentiful than what you'd expect if they only made them for
a few months.  I bet they were made for the last year or more of the run.
I know there were more than one ROM variation within the beige as well.  If
could be the last ROM variation was produced for the last few months, but
not all beige models.  Check the ROM chip silkscreen date codes perhaps to
confirm this.

Re: Odd Ebay auction showed up today...

I noticed that he had not been selling as much lately, I guess he ran out
of the good stuff and needs to close out the business, or raise new funds.
His normal list of Altairs and such appear to have all been sold.

Re: Off Topic Any customs brokers on the list?

[william degnan via cctalk]

Paul,
I used my business incorporation (EIN) to get items through from Canada to
the USA by car, through customs  I contacted the FedEx Trade Network and
purchased a single transaction bond premium from them.  I declared the
computer items as "display exhibit props" avoiding computers so as not to
confuse vintage computers with working current production computers.  They
created a AWB / BL Number for me to use to get through customs, etc.  It's
kind of a pain so get all this in advance if you're trucking anything
through from Canada into the USA.   Easier to get the items into Canada I
seem to remember.

RX01 and RL01 on same UNIBUS system

[william degnan via cctalk]

Just curious,
Is there anyone out there with a combo RX01 and RL01 on the same UNIBUS
system, today?  Are there any known issues?

I found a large box of RX01 disks, lucky me.  Working to get the RX01 drive
running, experimenting.  My particular PDP 11 does not like it (11/40) but
I think the drive is faulty, at least so far.  Much work to do.

What I was thinking is to format some IBM 3740 disks somewhere else (a CP/M
computer with 8" drives) and then use your RL02 running XXDP to turn them
into RX02 disks (they have to be formatted before you can use them).  I
believe there is an XXDP utility that converts an IBM 3740 format disk into
an RX02 disk with the higher capacity. Then you can copy files onto the
RX02 disk from RT-11, etc.  Am I correct that one can do this?

All of this of course assumes that you already have an RL02, drive running,
but I seem to remember you do.Right?

Re: Disk imaging with IMD - question

[william degnan via cctalk]

NOTE - I was able to make a bootable 8" DOS 6.22 disk even though it
slammed the last three tracks, on my imaging computer.  The computer
thought it was writing to a 1.2M 5 1/4 disk.

BUT you're saying a quad density SS disk.  I never tried that and if you
say it does not work then I can't dispute that without trying it myself.
