Yeah, I had a long, hard think about this while the Caldor Fire was
looking like it was about to come knocking on my doorstep this fall
and I was trying to prep myself for a short-notice evacuation and
decide what I could and couldn't take (read: leave stowed in the trunk

So, some months ago, I was in an electronics surplus store and picked
up what was obviously an X terminal - tiny metal slab with a VGA
connector, serial & parallel, AT keyboard, and RJ45 "communication"
port. I got it bare, without the external PSU that would've gone with
it, and I've since been unable to determine just what the heck I'm
supposed to feed this thing. It's a standard barrel jack, but there's
no markings on the case or the PCB to give any clue as to what
voltage/amperage or polarity it expects, and Google has been no help
at all. Does anyone have any recollection of these things? Any idea
what they want for juice?

To throw an extra mysterious wrinkle into this, when I popped open the
case to get a look at the PCB, I found that, apart from the CPU, DART,
and ROM, the only non-glue ICs on the board were an 8K SRAM and a
W82C476 RAMDAC - but 8K isn't even remotely enough for a VGA screen,
not even a monochrome one at VGA resolution! Am I missing something on
how these things operated? Given this, my only guess would be some
kind of insane networked-framebuffer scheme where the host would blast
video data in on the fly, but there's no way this was even 100Mbps
Ethernet, and 10Mbps isn't nearly fast enough to transfer 150KB at

This one has always boggled me, because it's the one aspect of the

Agreed. While I'm much more favorably disposed towards C than you are,
the increasing homogeneity of almost all modern languages is
discouraging and, I think, detrimental to the field as a whole. Forth
and Smalltalk alike were eye-openers when I discovered them (and
Smalltalk in particular was a breath of fresh air, after I'd spent
years failing to ever really grok OOP with the likes of C++ and Java,)
because both presented genuinely *different* and beautifully
consistent ways to think about structuring and specifying a computer
program. These days, though, outside of deliberately jokey
ultra-esoteric languages, it's pretty much just a bunch of
domain-specific Java/Javascript knockoffs from horizon to horizon.

It's marketing - consistency there is a non-consideration, if not
actively striven against. The whole saga with CP/M on CBM was a
boondoggle - the CP/M cart existed because business customers wanted a
CP/M add-in to run their spreadsheets and their whatnot, but it didn't
end up being a good fit for reasons already stated (slow CPU, slow
disk, 40-column only.) The 128 improved on those points, but not
nearly enough to become competitive with the advancements CP/M
machines had made in that time, and in the process wasted precious
man-hours and drove up the cost and complexity of the unit - and all
the while CP/M had been losing ground to MS-DOS in the business market
for years! But marketing promised it, so it had to happen... :/

There's definitely truth to this. The main thing that makes a good
programmer isn't memorization of language features or syntax, it's
good mental organization and thinking habits; the ability and practice
of really *thinking through* the steps involved in solving a problem,
building a solid mental model of the relevant data structures and
algorithms, and then breaking those down into component steps until
one arrives at a suitable representation in native-language
operations. If someone has a good understanding of that, they can
apply it (with varying amounts of blood, sweat, and tears) in any
language; if they don't, there's no language in the world that can
impart it to them (no matter *what* the flavor-of-the-decade Savior Of
All Programming Forever is - "Try Swift! It's the new Pascal!")

*That said,* there are definitely some languages that are more
conducive to building these habits than others (and, within each
group, many that emphasize different aspects more or less strongly.) I
can't speak to COBOL as I've never had cause to get any experience
with it, but I would say that BASIC (as in, the old-school,
unstructured BASICs of the Bad Old Days) really does teach you a bunch
of habits that you end up needing to un-learn as soon as you start
working with better languages (not even *newer* languages - ALGOL and
Lisp both predate it.)

Line-#-and-GOTO programming imposes the same burden of bookkeeping and
space-management on the programmer as direct machine-code monitor
hacking and the most primitive assemblers, but without any rational
explanation as to why, so that any novice attempting to create a
program of any real complexity ends up being instilled with a
superstitious dread over the ludicrous non-question of where to put
things - do I space statements N numbers apart? What if I need to add
more than N-1 intervening statements later!? Should I place my
subroutines on even 1000s for easy reference? Will the line numbers
even go high enough!? - the lack of scoped/local variables or any
parameter-passing mechanism for GOSUB makes any non-trivial
modularization nearly impossible, and the READ/DATA structure is just
flat-out demented.

And all that mental exhaustion *before* the newbie even gets to the
*real* challenges of learning to program!

Now, Dijkstra was a self-important ponce given to wild all-or-nothing
proclamations and manifestos (manifestes? Manifesti?) and even if we
give him the benefit of the doubt and assume that his statements
quoted here were meant tongue-in-cheek they're still pretty
ridiculous. And God knows the Appointed Language Messiah in that great
holy war, Pascal, was its own special breed of Hell for novices and
experts alike (array size as type qualifier? Just kill me now...) And
it's definitely true that plenty of people can and did learn to
program in BASIC and still went on to learn better and do Good Things
down the line. But there absolutely are such things as bad programming
languages.


VAX/Smalltalk-80?

2020-04-01 Thread John Ames via cctalk
Just in the middle of getting a fresh OpenVMS install set up on my
VAXStation (the original having been done years ago when I barely had
any idea what I was doing,) and looking through various repositories
for interesting software to put on there, and I got to thinking about
something I recalled reading about a few years back.

I know from the book "Smalltalk-80: Bits of History, Words of Advice"
- http://sdmeta.gforge.inria.fr/FreeBooks/BitsOfHistory/BitsOfHistory.pdf
- that, back when, there were two implementations of Smalltalk-80 for
VAXen - the first was Unix-based, done by an independent research
group, while the second ran under VMS and was actually developed
within DEC. This version - VAX/Smalltalk-80 - was headed up by Stoney
Ballard and Stephen Shirron; anybody know if there's a surviving copy
out there, if it was ever available outside DEC to begin with?

My rough guesstimate is that the boards in the backplane are memory

Ran into this at the electronics-surplus store just down the way from
my workplace and grabbed it on the cheap. I don't actually know what
it *is,* but the labels on the switches make it look a *hell* of a lot

claims of being "microprocessor-controlled," I looked at every board
inside the thing and couldn't spot anything that looked like a 16-bit
or even 8-bit CPU. Genuinely curious what this is, but I can't find
much on it online - the name pops up in a few archived documents, but
Bitsavers doesn't have anything for the company. Though the design is
attributed to Stanley Kubota and Edward Corby - looks like Mr. Kubota

All these years later, I'm still trying to wrap my head around what
the purpose of that in an OS/desktop environment/file-manager context
is. I guess that, say, you could have new file types implement their
own methods for things like printing, so the OS doesn't have to know
the details of the document structure or require a particular
application installed to be able to print it, but this seems like an
awfully limited use case to me - sure, it would be nice to have things
like audio and video codecs be universal and pluggable or things like
that, but I have a hard time seeing how it's all that revolutionary,
and I can easily see it being just as limiting as other non-OOP format
standards (after all, it's not going to magically add functionality
that the file format itself doesn't support, is it? And doesn't it
ultimately just come down to diking out a chunk of the application
code for the OS to use? What if two different programs both offer
their own handlers for the same file type?)

Have to concur with this. Even the "minimalist" (i.e. non-GNOME/KDE)
*nix "desktop environment" projects these days are getting so bloated
that I've given up bothering with them and set up an X environment one
component at a time. Currently running Window Maker with SpaceFM and
ROXTerm; getting it all properly set up and tweaked to my liking took
some doing, but the payoff was well worth it.

Now if I could only excise the GTK3 blight entirely, I'd really be set.

There's also the Afterstep/Window Maker crowd, open-source
reimplementations of the NEXTSTEP desktop environment, which predates
even Windows 3.x. Win95 was certainly very influential in the design
and refinement of many other desktop environments going forward, but
it's not the be-all and end-all of anything.

But this is kind of a questionable standard to begin with, because the
whole point in the Freenix world is choice. No distributions offer
those as default options during the install process, but all of them
(aside from CDE, which only just went open-source a couple years ago
and is still in the process of being cleaned up and forward-ported to
modern *nixen) are available in the repositories for most major
distributions, and all of them are still actively updated.

Kinda-sorta-not-really. BeOS (like just about everything post-1995)
takes cues from Win95, but its roots are in classic Mac OS and it
definitely hews closer to that in most respects, despite the absence
of a global menu bar.

Haiku says hi. Or would, if they could spare the time from trying to
awkwardly kludge Linux development models into a BeOS world.

This "aside from the things that don't match up with my argument, my
argument is flawless!" line of reasoning is novel.

I Am Not An Engineer(tm) but it seems to me that a taller cylinder
should be less prone to wobbling on its axis than a flat disk,
particularly if it's built at the scale of the drums I've seen at the
CHM where there's room enough to really bolt that sucker down. Bit
different than a 3.5" box with a stack of thin metal platters in it,
I'd think.

I don't know where you're located, but I'm in the US and have an NTSC
Laserdisc player. If someone can hook me up with a video capture card,
I'd be happy to copy the video for you.


Re: Wanted: small composite CRT monitor

I don't like LCDs much, particularly for low-resolution applications
where the fundamental badness of upscaling from a non-native
resolution is truly jarring.


Wanted: small composite CRT monitor

2017-08-22 Thread John Ames via cctalk
I picked up an Apple IIc this past weekend and I want to set it up
with a small monitor on my desk at work. Unfortunately, I seem to have
gotten rid of the small composite monitor that I know I had at one
point, so I don't have a good spare monitor that isn't a bit too large
for my workspace. I've been poking around looking at some options, but
I'm still waiting to find a decent one in my area, and if I'm going to
order online, I'd rather do it with people I can trust to actually
test the dang thing before selling it and pack it properly.

In short, I'm looking for a small NTSC CRT monitor or portable TV in
the 7-12" range. I'm not stuck on aesthetics, but it would be nice to
have something that would sit nicely atop the IIc. I wouldn't mind an
actual Apple monitor, but I don't want to pay APPLE MAC IPHONE STEVE
JOBS L@@K prices; otherwise, I'd be happy with any suitable composite
video monitor, color or monochrome. If you happen to be within
reasonable driving distance of Folsom, CA, I'd be glad to pick it up
and save the trouble of shipping. Anybody got one to spare?
