I've spent the weekend getting my new acquisition, an Alpha Micro Eagle 300
with AMOS 2.3a and AlphaTCP on an AM-65 console, up and running. After a few
false starts, I now have the Ethernet configured, TELNED set up for remote
login, FTPD, and HTTPD.
Eventually I'll probably put it out there as a "fan server" running on real
hardware, put up some FAQs, etc.
However, I can't for the life of me find any VT100 or VT100-compatible TDVs
in DVR:, so I've been logging in as a dummy terminal with TELTYP. This is
pretty crufty. Anyone running an AM system with a VT100-compatible TDV I could
"borrow"? VERIFY TCP checks out, so I don't think I'm missing any files.

Rather than replace the anvil in my 20-year-old hand nibbler (which
I'm not sure that I can do anyway), I've decided to spring for a new
one.
Both Adel and Klein offer hand sheet-metal nibblers for about the
same price. Which one is better?

Yes I know. The shipping / voltage issue is a big problem for me.
However as a stopgap I have found a non-DEC monitor marked R G(Sync) B.
(If that's not sync on green I don't know what is)
So its cable time this weekend and see if we can't get some colour out
of the Rainbow.

It is hard for me to admit this, but I have a PDP-11/23 that I will
never get around to doing anything with. I need to find a new home for
it.
It's complete, was running, needs RL02 disk packs. Comes with two
VT100's and an LA36 Decwriter II. It is configured exactly as in this
picture (I don't think it's a plus though).
http://hampage.hu/pdp-11/kepek/1123PLUS.JPG
I have cash into this project. I'm wondering if there is any value to
this system. Have PDP's reached "collectable" status yet?
James -
Hi, I picked up a job lot and about half of this is DEC. I'm not a DEC
collector (shock!!) but I know many of you are.
I'm in Southampton, UK. I'm happy to post this stuff (UK only, sorry!)
if you cover costs, but would of course prefer collection. I don't have
any working DEC kit so this is all untested. If you get something that
works and you feel is worth money then make a donation to Cray-Cyber
(www.cray-cyber.org) or your favourite charity :-)
Hardware:
Approx 90 * TK50 "CompacTape" cartridges. These are all in cases, many
have VMS 5.5 or system backups. Some look new. There's also about 10 of
"CompacTape II" cartridges. I'd like to cover my costs and ask ?50 for
the whole lot (DHL delivery would be about ?13). I may split if there's
no interest in the lot.

From Key -----+ | | +----- To Key
Key 12V----------+ +-------- Key Gnd
Components :
------------
DA15S socket + hood (to fit Rainbow video connector)
DA15P plug + jackposts (for VR201 connection)
4 off 75 Ohm BNC sockets (for monitor connections). You could use other
connectors, like RCA phono, but BNC are standard.
RJ11 socket, chassis mounting (for LK201 keyboard). Chassis mounting
sockets of this type are very hard to find. I ended up making a bracket
to clamp a PCB-mounting one to the panel
Metal box of a suitable size to hold the above connectors (apart from
the
DA15S).
1m cable. At least 4 75 Ohm screened cores and 6 single wires. I used a
'unversal SCART cable' which has 6 75 ohm screened cores (I simply
ignored 2 of them), a 4 way screened cable (I used this for the 4
keyboard connections) and 4 other wires (2 in parallel for each of Power
12V and Power Gnd).
Possible monitor combinations :
-------------------------------
1) VR201 only
This is pretty useless, but you can connect a VR201 mono monitor using
the DEC lead to the DA15P on the box. Connect the LK201 keyboard to
either the VR201 or the RJ11 on the box.
2) Standard composite mono monitor
Connect monitor input to 'mono' BNC on the box. Connect LK201 to the
RJ11
on the box. This works just like a VR201, but you can use any monitor
3) VR201 and separate mono graphics monitor
Connect VR201 to DA15P. Connect LK201to either RJ11 on the box or to
VR201. Connect second (composite) monitor to the 'green' BNC. You can
use
the dual monitor driver for GSX and have text on the VR201 and graphics
on
the second monitor
4) Two composite mono monitors
Connect one to 'mono' BNC, other to 'green' BNC. Connect LK201 to RJ11
on
box. Using the dual monitor driver, you get text on the first monitor
and
graphics on the second monitor
5) RGB (sync-on-green) colour monitor (e.g. VR241)
Connect monitor inputs to BNCs as follows :
Red - Red
Green - Mono
Blue - Blue.
Connect LK201 to RJ11 on box. This gives the standard DEC color monitor
connections giving green text and colour graphics using the colour
monitor driver
6) RGB monitor and VR201
Connect VR201 to DA15P on box. Connect LK201 to RJ11 on box. Connect
color monitor as follows
Red - Red
Green - Green
Blue - Blue
This gives separate text and colour graphics displays when used with the
dual monitor driver
7) RGB monitor and composite mono monitor
Connect mono monitor input to 'mono' BNC. Connect LK201 to RJ11. Connect
colour monitor as follows
Red - Red
Green - Green
Blue - Blue
This gives separate text and colour graphics displays when used with the
dual monitor driver
Hi all,
saw the discussion about the rainbow, and decided to give my a try.
But, I don't get any color output ?
The color option is installed ;-)
BTW, the cable I'm using is the BC06. Manual says, that it should be
BC17. Anybody knows it is the problem ? What is the difference between
them ?

Jules,
My PERQ T2 does exactly the same thing. The dreaded
010.
Eventually if left for a while (10mins+) it goes to
013 which I think is drive time out.
Once I get chance I'm going to put a Logic analyser on
the
disk terminals to get a better idea what's happening.
I also tried a ST-506/412 drive with the same result.
Tony also mentioned that its possible to connect an
analyser
to the front of the CPU card to see where the CPU has
stepped to.
Cheers

For rust prevention, has anyone tried volatile corrosion inhibitors? A suitable-looking one is the "Small Enclosed-Area Corrosion Inhibitors and Corrosive-Gas Absorber" (http://www.mcmaster.com/, catalog page 2049, $13 for one good up to 11 cu.ft) or those at http://www.theinhibitor.com/ .
The one at McMaster-Carr says it is good for electrical enclosures, but I wonder if there are any harmful effects on plastics or IC's.

I'm in the process of preparing to move house and some stuff is just going
to have to go!
If I don't get serious expressions of interest* within a week they are
going.
(* A "hell no, that's too rare to throw away" might lead to a stay of
execution ... but
unless quickly followed-up won't do much good)
Items will have to be collected - they are currently part of the contents of
a 20' container
in a small industrial estate near the A127/A130 junction (not far from
Rayleigh).
It is just possible that I can be persuaded to make one trip up to Bletchley
if there is
interest there.
For the moment I have 3 classifications:
SUN stuff
Apple Mac stuff
Other
The SUN and "other" items that don't get interest here will find their way
into a skip.
The Mac stuff is to be considered one lot (take it all or nothing) and if no
interest here will go to eBay
(and then to a skip if no interest)
Haven't yet inventoried the SUNs - there are several 10s, 20s, a couple of
5s and
some Ultras - at least a 1, some 30s, possibly a 60, possibly a 10
loads of MBUS and SBUS modules including lots of ROSS processors also
some memory and SCSI drives.
(I'll be keeping a couple more SUNs)
In the "other" category are, at least, the following
personal DECstation 5000/25
DEC 3000 400
Silicon Grapics O2 (this has Irix 6.5 - but I don't have a known id
password ...
and it uses SGs own filesystem so I can't just put the disk on a SUN
and
hack it that way.
a few other weird and wonderful boxes and other minor items
(such as the board set for connecting two Novell servers together in a
SFT III setup)
An unusual PC - dual P90 with PCI and EISA slots (2 adaptec SCSI boards)
an A3 plotter - cannot remember whether it is HP or Roland
when I get round to finding it there'll also be a HP unix workstation
various home computers of the BBC & ST/Amiga eras (not yet sorted)
The Mac list is quite long
a SE, a IICi, Quadra 650
Powermacs - 6100/60 (x2) 8600/230, 8500/180, G3 (x2)
these have all worked, but testing last week only got fully positive
results from
the 8600 and one of the G3s
also some keyboards, monitors, books, and software
I'm still delving into my garage, loft, and spare bedroom ... more may yet
be found :-)
email me if you are seriously interested - reply to the list if you think
someone else
should be :-)

In an EETimes online article today, I read the following paragraph:
"Among its other features, Morrison said COSA allows more dynamic
changes in software than traditional methods, enables fast pre-
empting of threads and brings a new level of traceability to
processes. It is also easier to debug because it does not use the
structures of nested if-then-else statements known as spaghetti code
popular in conventional programming languages."
Nested "IF-THEN-ELSE" is now spaghetti code? I'd always understood
the term to mean code with lots of conditional GOTO statements (In
FORTRAN, sprinkle in a bunch of computed and assigned GOTOs and
you're talking real pasta).
When did the meaning change? Was it when the GOTO statement was
pretty much deprecated in just about every modern programming
language? I can recall when "structured programming" was popularly
held to mean "no GOTOs".

Hi Tony
I just looked up some of what one needs to know.
If one jumpers the SW to the OP, the 4 push switches
control the intgrator action.
IC stands for Initial Condition ( you can put a specific start voltage
on the caps ).
HD stand for hold ( useful for taking reading of several outputs at the
same point in the simulation )
OP This is the normal operation with the integrators working from model
stimulous.
RO it the same as above except that it does a IC after some time
length ( specified by the rotory switch ).
The SW pin could also be controlled by some opamp or external
signal. There are three voltage levels that control initial condition,
hold and operate.
The web page also says how to connect the multipliers to opamps.
There are a number of control courses, at various universities, that
show how to configure the Comdyna.
The value of the resistor shown as 1 is 50K and the .1 is 5K.
Knowing this, one can use external resistors to extend the
setting used. Of course, the two pots in the center could
be used. The coef pots are useful for offsets, stimulous and
initial conditions.

Hi
One should not that while the family codes are correct,
the rev levels for the UniPak are different than those for
the UniPak2. I wonder how it responds if the unit is not
up to the specified rev? I guess if one tried to select
one that wasn't supported, it would error out.
Does anyone have any schematics for the various
uP adapters. I'd really like to program 8751's and 8748's.

Hi
State machines have their place. A calculator is a good
example. It is too bad that not all software makes sense
as a state table, just as an all OOP solution can be
clumsy.
Some of the best software I've seen was written by a friend.
It was for a Reed-Solomon error correction. When he showed
the code to his manager, the manager said he sent the wrong
file. What the manager thought he saw was the specification
for the code. What he really saw was the actual code.
When code is written that well, anyone can maintain it.
I've seen bad spaghetti code done in most any language.
The worst was still in BASIC.

Hi
Yes I knew about the comp video. Fortunatly a kind list member has a
VT201 I can have.
Now the hunt is on for a VT241. That's the companion DEC 13" RGB colour
monitor.
Regards
Rod

Just about any CCTV monitor, basically.

I understand that there are standards for the width of an EIA rack,
as well as bolthole size and spacing on the rails, but is there any
sort of standard for *depth* of an EIA rack?
The one I have measures 28 3/4" front rail to rear rail, which I
suspect is deeper than usual.

It appears I need to take the bus to DEC101:
I have a MicroVax II in the BA23 case. I'd like it to have a SCSI
card. This machine takes qbus cards, I believe.
I recently acquired a CMD CDU-720 card, which appears to be a nice
(and nicely documented) card that supports all kinds of devices, and
speaks MSCP to the Vax. But, it is Unibus.
Am I out of luck here? I gather there are bus converters. Are they
rare? Are they reliable? Should I save this card for the day I
happen upon bigger iron?
Thanks!
