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 ?
Thanks

I have 5 "NOS" PET 2001-N/3000/4000 series keyboards for sale.
I have 8032 64K memory expansion kits and related items too, unfortunately
no 8032 keyboards.

Hi Jochen and others
>You may try NetBSD.
I looked at *BSD but it seemed to only support the Ultra 1E and not the
Ultra 1. Tried Ubuntu Linux, that died while trying to partition the disks.
Now installing Aurora (a Redhat spinoff), that seems to be working nicely.

I'm surprised nobody commented on the SAM Coupe. First time I've even heard
of it, to me it's one of the more interesting machines in the haul, just
>from a "look how far they went with this when newer technology was
available" point of view.
The Acorn RISC PC also seems to be something a lot of work went into. Pity
it dead ended.

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
Ian

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".
Cheers,
Chuck

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.
