RCA 1801 disappeared from face of Earth forever... You would be better off
to purchase at:

http://www.sunrise-ev.com/membershipcard.htm to use 1802. The 1802 was very
successful microprocessor that replaced 1801 because it required to have a
pair of chips to work together. I believe I saw 1801 was more than 30 years
ago.

Good luck!

My chief complaint is that it suffers from a readability problem.  Part of that 
is for the “updates” sections at the start of each page.  Let’s be serious, the 
pages haven’t been actively updated for years, so that’s no longer really 
valid.  There is new info out there, and a lot of links I’m sure are dead.

Though what’s really changed is my attitude towards emulation.  This might 
sound odd, but when I wrote the pages, I wasn’t that much in favor of 
emulation, and was more inclined to run on the real hardware.  It’s a heck of a 
lot more practical to leave SIMH running on a VM, than it is to have a real VAX 
or PDP-11 running 24x7.  Then again the main source of inspiration for the 
pages was the PDP-10, and I’ve never viewed running one of those at home as 
practical. :-)

Mind you, while I have a couple emulated VAXen running, I also have a real VAX, 
and a rather nice Alpha running 24x7.

It seems that your site could get some updating, indeed. Some links
are dead and some point to your old website, or something. And I think
it could be better to have one central "what's new" section.

Other than this, I can use it very comfortably in elinks - including
left and right clicking the links.

In other words, you would like to put some more stuff to your website.

I have had a look, and I think that perhaps you should try to select
some more recent tool, or tools to do this new job. Unless you would
like to keep using the previous tool, but wikipedia says it is
discontinued. Once you have a tool, the rest is just some time and
maybe perseverance. Out of the top of my head, before I drop:

 - Emacs + org-mode - myself, I would have looked at that first,
   mostly because I have already invested some time into learning
   Elisp, Emacs, and am able to use org in some basic way, so it could
   be perhaps just learning a bit on top of it - but if you do not
   know Emacs, this would be a very uphill project. It might require
   writing a snippet of Elisp or two.

   Some people have created nice pages with org-mode:
   http://orgmode.org/worg/org-web.html

   like this:
   http://srandby.org/

 - variation of above - more code snippets to help yourself, in some
   yet another language

I have never made a website in this way, so I have zero practical
knowledge about process. I suspect it is very easy as long as one
follows some path described in manual, and then gradually harder when
it comes to bending org-mode to one's specific wishes.

 - adopt some wiki and remake your new site in its image - I am sure
   there must be something not so complicated, not depending on stuff
   I myself consider untrusty (like PHP, which many people use
   happily, but I would rather not). Advantage: you could probably get
   going in a day or two, site should look ok in many different
   browsers and you do not have to start from designing website
   structure, just start putting content into pages and tag it.

Anyway, I would stay away from more complicated solutions, whatever
they are written in, unless I was ready to read the source code on as
needed basis (I am ready with Elisp/Emacs, so this would I choose, or
at least considered - I am not ready to learn PHP and keep it ready to
use, so I do not choose Wordpress, even if it can be used by people
with almost no tech knowledge, from what I have seen - and besides WP
has a baggage of its own security problems, so using it seems to me
a bit like plowing a minefield).

Yeah, emulation is even more practical for those of us, who have no

I have browsed it just few moments ago with lynx, emacs-w3 and my new
textual favourite, elinks (it multitabs!! and shows tables!! and I could
play with configuration a lot, so on 256-colors-enabled term it looks
a bit nicer to my eyes). In all them, and in some old graphical one,
the site looks decently.

As of "modernisation"... You know, just MHO and stuff but sometimes
when I see modern pages it seems like their creators have had been
abducted to some sect and brainwashed clean. I have 1600x1200 and I
like to have some other window besides browser (say, an editor, like
emacs). So I open such page, and the browser has about 3/5 of estate
and I am not going fullscreen, no way. And there is huge menu on the
left side, so I can choose. And there is some (expletive0) "top bar",
all white and empty, or maybe with page title (I already have one
(expletive0) title on a title bar of browser window), then there is
(expletive0) bottom bar, all empty. And for a text, there is area left
which is about five to ten (expletive0) lines high. There is no
(expletive0) way to make those (expletive0) elements go the (subseq
(expletive0) 0 4) away. The last resort is to turn styles off, which
quite often gives me almost the view that I would like to have, plus
(quite often) a parade of (expletive0) leftovers from the leftside
menu, which after switch takes more than 90% of (expletive0) web
page. I swear I do not make this up. The usable part of the modern
webpage is on average the (expletive0) ten percent, as measured by
scrollbar - and sometimes even less.

The only reason I keep using very old Opera 1x.x is because it:

A) does not multithread (so when I load heavily crapped page, it only
(subseq (expletive0) 0 4)s with one core of my cpu max, rather then
(expletive0) with me fulltime

B) is able to show very decently a page with styles turned off; this
also sometimes means lowering core usage by half (the usage which is
there even when (expletive0) browser is expected to sit on its
(expletive1) and do nothing).

C) I turned a lot of CSS off by default, but I am not quite sure if
this really works (software, trust, does not compute) - and I put
fixed/monotype fonts wherever I can see them, because I love the idea
that space is same width as "i" and "W". So all the job done to max my
pleasure with downloadable fonts is lost, and (expletive0) good for me.

I have tried switching to Firefox, but somehow having eighty tabs does
not work very nicely there, for me at least. But I launch it when
there is something that poor Op cannot render properly. Overally, I
have few browsers opened as day goes by, one for Common Lisp docs,
another for casual reading, one for sci articles heavy with equations
and gfx (mostly up-to date rendering 'gine), few text browsers for
interesting stuff, books or longer reads etc. I have recently started
to experiment with Dillo - this is very nice piece of (expletive2),
recommended to everybody even if it not always shows things, kind of
like text browser with graphics (sometimes) and multitabs. Perhaps
will also try "old new" Mosaic - the old one got lost during
innumerable system upgrades.

As I could have observed, plenty of people out there think that
"modern" means "optimised for mobile", but what does it mean in
practise? The text, i.e. useful part of the page might take 10
kilobytes (optimist, me, always), there might be even useful pictures
on it, and then there goes a (expletive2)load of javascript. Megabyte
is a, kind of, norm. So, this (expletive2) eats my download/upload
quota, for which I pay (in theory, because I never was in such
position). And then it starts running and eats from my battery, which
can be loaded for peanuts, but who wants to recharge every few hours -
this is supposed to give me mobility, but not to/from wallsocket.

Which is how I came to brainwashing - the words being used are
redefined. Optimised no longer means what it used to mean. Now it just
means conformance to some group's standard. Optimised for pats in a
back, just not from enduser (some endusers dream of packing boot deep
into webdevel's (expletive1) and leaving it there, and the second boot
would go to their halfbrained tasteless boss'es (expletive1), only
deeper).

For me, "optimised for mobile" is something like HTML1.0, or maybe
even 3.0 (if this is when tables were defined). And "modern" is
unimportant, if a goal is

Given the way you phrased it, the correct replacement  for 'whatever' is M

Re: C64 to a good home

2017-10-22 Thread drlegendre . via cctalk 
Hey Kevin.

This is all good advice, but there is also another way to go - and it's a
bit more future-proof. For about the same cost as the Zoom floppy, you can
get a device called an SD2IEC or similar. It's very simple - it connects to
the IEC (disk drive) port on the C-64 and accepts a micro or mini SD card.
This way you only need copy your C-64 titles to SD card (any way you like)
and they will be accessible to the C-64. The device behaves like a 1541  /
1571 drive.

I say the SD2IEC is future proof, as it doesn't rely on original 15X1 disk
drives or 5-1/2" media, all of which could go away someday.

Now _personally_ I use a home-built XM1541 cable with opencbm (free/OSS) to
transfer my images to genuine 5-1.4" disk. I only do this as I'm too cheap
/ broke to buy something else like the SD2IEC. It is exceptionally stable
and reliable - once set up, it "just works". Though if you a) run Linux and
b) accept a kernel update you will need to c) recompile & re-install
opencbm as the module is built specific to the running kernel. This takes
only seconds, literally.

Have a look at mbsync/isync if you still haven't
done anything about it on those two years.  LOL
It does exactly what you wanted.

No, it turns out the answer is to set the preamp gain at spec.  It
appears to do nothing but create more problems if turned up higher than
that.

It was worth a try.

Cloning A Hard Disk Over The Network Using Ultrix

2017-10-22 Thread Rob Jarratt via cctalk 
I have a couple of hard disks I want to make dd copies of. I have Ultrix
running on my DECstation 5000/240 with the disk I want to clone attached to
it. The trouble is that I don't have enough disk space on the machine to
clone the disk and then grab the image using FTP. I have been trying to find
a way to pipe the dd output over the network to a SIMH Ultrix machine that
has plenty of disk space. I tried piping dd into rcp, but rcp doesn't seem
to take input from standard input. I have looked at cpio, but that too
appears not to accept input from standard input.

 

Unix is not my strong point. Are there any other ways I could pipe the dd
output across the network to a machine that has enough disk space?

 

Thanks

Re: RT11 Disk Partitioning and RQZX1 SCSI controller

Is there a potential problem here?

I have an 11/53 microPDP11 with a RQZX1 controller connected to a single
DEC DSP3043 drive (535MB) and a single RX33 floppy.

The autoconfigure setup in the RQZX1 puts the hard disk at DU0 and the
Floppy as DU1.  OK.  I boot RT11 from the disk, V5.7. Works fine.

I would like to use some of the extra space on the disk by setting up
RT11 disk partitions.

However, one of the partitions is DU1, but that is what the Floppy is
called.  How do I stay away from what seems like a conflict?

Doug

SET DU2: UNIT=0,PART=1
SET DU3: UNIT=0,PART=2
...

** reboot **

INIT DU2:
INIT DU3:
...


Thanks, it did work. I'll just stay away from DU1:.  I forgot about the 
reboot required for these changes to take effect.
