6bits was the "byte" size for the PDP-8 (swap acc halves).
9bits was the byte size for the PDP-10, I believe IBM360 and CDC6600
12 bits was link-8, PDP-8 and PDP-12 (likely others).
9/18 the pdp7 (first home of unix).

Thanks for this first info. The scanner does not bear the Plustek name or
logo, but their web site lists a "Scan Plus Color 3000" (possibly color variant
of mine), for which they still have a driver. The bottom of my scanner has a
label on it with two checkboxen, "ScanPlus Gray 300" next to the checked and
"ScanPlus Color 3000" next to the unchecked one, so obviously the used at
least the same housing.
Unfortunately, they only describe setup procedures for parallel port
scanners (which have a second connector for the printer cable) and USB scanners, so
I'm still lost as to which kind of interface I need to connect mine.
I had already found and downloaded the files from the Italian site.
Sincerely yours

Most of the software in use in the UNIX world is free. Of course
there ARE commercial packages, but...with very few exceptions, for
every commercial package there's at least one free one that does the
job as well or better. It's possible that I'm preaching to the choir
here, but one of the common misconceptions that really bugs me is the
notion that "unix == expensive", when in reality it's just the
opposite. (The same goes for "pc vs. real computers" in the "I use a
PC because I can't afford a Sun or an Alpha" case...)

FPGA and CPLD stuff are some of the exceptions that I mentioned in
my paragraph above. For that stuff we're pretty much stuck with
Windows due to the shortsightedness of the vendors. There's nothing
we can do about that at this point, as far as I can tell. :-( I curb
that problem by using Windows (under an emulator of course) ONLY for
the stuff that I can't run under a real OS.

I agree 100%. Needless to say, we're trashing this compiler after
this project. :-) The fancy GUI is nice, but frankly I can be more
productive with xemacs and make.

Not necessarily...I've used at least four FREE 8051 C compilers under
UNIX, nearly ten years ago! $2000 *is* high, when most of the 8051
compilers I've used cost $0.

So just what is it that classifies the C64 as a "toy" computer ? When
it was released, it was far more capable than the existant Apples,
Ataris & Radio Shacks (& a damn sight cheaper too).
Indeed, out of all the machines then in production, which one still in
use now is still capable of (more or less) doing what modern machines
can ?

Hi All again.
I have to say the Vax I got last week has been heaps of fun, picked up a
couple of bits for it today, like about 20 backup tapes (unfortunatly not
TK50 tapes) And a Nice VT420 Terminal.
Anyway decided to let VMS wait for a little before I try and learn this
odd but interesting system, (I am going to be joind decus so I can get new
VMS media as the machine didn't come with any) so I have had a look at the
other avalible OSes that are avalible for the VAX.
A quick question was ULTRIX ever avalible for the uVAX 3100/80?
The two "free" operating systems that seem to be avalible for the 3100/80
are NetBSD and OpenBSD (there seems to be a version of linux but it seems
to be quite imature.)
I now have had a play with both (and If anyone ever needs a hand setting
up either of these just give me a yell.)
The NetBSD install was realy easy, I booted the vax via the network, and
then did a [ctrl] + [z] and then using ftp pulled the .tgz files to the
vax and installed the os from the local hard drive. The only issue was
that the NetBSD install was sparse to say the least, and after compiling a
couple of things (which was quite slow, but no where as slow as my first
linux pc ;) I decided to give OpenBSD a go.
OpenBSD is great, still it doesn't have all that I want, but has a lot
more than NetBSD. The install is a little hairy in places, and it took me
a while to configure the FreeBSD i386 box I am using for a boot server
(the OpenBSD net boot process is a little differnt that NetBSD) but the
install went painlessly.
To sum up, and sorry if this is a little off topic. If anyone is looking
for something other than VMS to run on their Vaxes, I would reccomend
OpenBSD over NetBSD.
I Hope I havent bored you too much....

Atari's TOS wasn't based on MS-DOS either, and it used the exact
same filesystem.
To answer your rhetorical question, actually, I hadn't noticed.
I did notice that it was significantly different from ODS-2. :)
Perhaps I need to be more clear here -- this guy really thought
that somewhere underneath the Mac GUI, there was a copy of MS-DOS
on every Macintosh. He had nothing to offer as proof, except that
no computer could possibly function without it. (I'm really
serious here...)

This set includes the circuit boards reproduced (actually produced-retro)
>from the original plans, and the front panel with lettering, and the red
lens. I purchased these directly from the man who produces them and he has
assembled a number of Mark-8's in the past and is very knowledgeable on their
assembly. He includes an excellent CD with reprints of the original Radio
Electronics articles and his own very helpful notes. Here are a couple of
pictures:
http://www.classiccomputing.com/mark8.html
Here is more info:
The First Hobbyist Computer!
The remarkable Mark-8 computer was described in the July 1974 issue of Radio
Electronics. A landmark in computer history, it was the first hobbyist
computer. At this point in time, most engineers didn't, or couldn't believe
that a real computer could be constructed with the new fangle Intel chips.
But Jon Titus proved them wrong with the affordable Mark-8 computer. The
Mark-8 is a .5 Mhz 8008 based computer that preceded the Altair 8800 by about
6 months. The 8008 was Intel's first 8 bit processor and was developed along
with the world's first processor, the 4004. Only plans and pcb boards were
available from the creator, Jon Titus, everything else had to be provided by
the builder.
More on the CD from the creator:
Also included is a CD that I put together containing a copy of the original
Radio Electronics article and supplemental 47 page construction article; a 50
page manual I created detailing my experience and hints debugging this
computer (with many photos and full scans of completed boards); aboueers
informed before Byte came out, its a treasure chest of historical information
about the Mark-8 and other early computers, the January 1975 issue is
especially interesting, this is when the Altair was introduced)
I paid $180 for this set and I have come to realize that I do not have the
talent needed to do the precise soldering, testing, etc. and there is the
task of locating the remaining parts for the computer. This is over my head I
believe, so I want to pass these on to someone else. $150 plus shipping, an
excellent deal. Don't miss your chance to build this classic kit.
Best,

That is sitting in the back of the van sitting in my driveway :-)
In the morning I will see what it's status is (Dave believes it works,
but doesn't know 100%... worst case, I will probably canabalize my LJ 2

Sorry, had to rub it in (isn't often I have toys others want)
