?It?s easy to wax nostalgic about old technology--to remember fondly
our first Apple IIe or marvel at the old mainframes that ran on
punched cards. But no one in their right mind would use those
outdated, underpowered dinosaurs to run a contemporary business, let
alone a modern weapons system, right?
Wrong!?

I don't have a REAL Commodore 64, so I unfortunately cannot mess with the physical hardware.
But!
I have a https://en.wikipedia.org/wiki/C64_Direct-to-TV and it seems that it is pretty hackable.
Should be interesting to mess with?unfortunately I have no idea where the soldering equipment is here so I can't do much with it. ;)

I've never seen an Epson QX-10 - I don't even know what it is.
Whatever it is, one way to approach it is to make a dummy load for the PSU
which resembles the normal load on it as far as possible. If the PSU continues
to malfunction when feeding only the dummy load, the problem is almost certain
to be in the PSU itself. Dummy loads for low voltages can often be made from
bulbs for use in cars, including dual filament bulbs which had to be replaced
because one filament failed.
Another useful thing to do is to look for bad connections in the PSU. If it is
constructed on a printed circuit board, while feeding the dummy load, try
examining the underside of the board in a darkened room while tapping the board
with something insulated. You might see or hear tiny sparks indicating the
location of a bad solder joint.
Be aware that the PSU probably contains high voltages and that these may
remain for a considerable period of time after power has been removed,
particularly if the unit is faulty.

Peter Coghlan.

Unfortunately, I cannot tell if it is still working, because I have lost the

I think this digital scanning of old film is entirely apropos
for computer preservationists. Many early computer animations
were recorded this way. It seems like many film-to-digital
conversions happened by way of steps that involved NTSC video.
That's a shame, and reminds us of the lesson of the value of

I totally agree with that, too. I remember when I was doing my thesis, I
printed it on the department's Qume daisywheel printer. They had the
service manual with complete schematics. It was very interesting, with
analogue servos for the carriage motor. A very nice piece of equipment.
Not to mention the 11/40 we used, or the big 80 MB Ampex disk drives.

Some processes are better today. I recently had some old (1940s to '70s)
8 mm family movies scanned digitally.
The service cleans the film and uses a wet-gate process to reduce scratches.
They scan each frame digitally at HD resolution (1920 x 1080) using
even LED illumination. They scan the entire film edge-to-edge. Many
old cameras exposed the entire width of the film while the projector
only showed the majority of the middle, so you see more image than
ever before. I asked for a digital movie file for editing, so I sent
them a hard drive. The results are astoundingly dramatically better
>from what you got from an old projector. No playback jitter
>from worn sprocket holes. Bright, even illumination.
It's far better than the film-to-VHS transfer I paid for in the early 90s.
(Private YouTube example links available on request.) All this for a
dime or two per foot. I'll be able to edit digitally and provide
family members with DVD or Bluray copies.
The same is true for restoration and duplication of old family
photographs. With a digital process, you can undo damage and
easily multiply copies.
As with the classic computer avocation, it can come with regrets, too.
I wish I would've rescued 1930s family films from a distant cousin
who passed away a decade ago. I had a VHS copy of some of his films,
but not the originals.

I've looked in all the usual places and can't find any manuals for the
D200 - does anyone have a scan?
I know there are manuals for the later D410 and D411 floating around -
but I would like to get some definitive details on the D200.
(Also - still looking for any help with the MV/2500...)

Then I would be one of those very few. I find hardware and system
software (operating systems, database managers etc) equally interesting.
Actually, my view is that they are to a great extent two different
incarnations of the same thing: The hardware is a physical machine that
executes programs, the operating system is a kind of virtual machine
which executes user programs. Then there is virtual machine software,
that is also very interesting.
I wrote a very simple operating system once in my career, now I am
playing with writing another one in my spare time. Some day I will most
likely also design and built my own processor, whether with discrete
logic or an FPGA I am not sure, perhaps both.
And then the physical experience of an actual old machine running is
something special, quite like driving an old car or riding on a steam
train.

You'd think by now I'd know better than to start a thread like this
while on digest mode. First, thank you to everyone who replied. I got
at least something out of every post so far and that's no small thing.
I must have misread something along the way as I thought the /23 had
separate I/D spaces. Good thing to have that correct now. I'd not mind
getting one to run it for it's own sake but to get it thinking it
could do something it couldn't would be much more annoying.
Thank you to the pointers to additional docs - the field guide as
especially nice to find as I'm still learning my way around the DEC
module names. The chassis information was quite helpful as well.
As for why, well...
I graduated HS in 1982 & took a short detour into the Army so I missed
a lot of the "glory days" of some of the things on this list. I
started with micros and as a student the closest I got allowed to the
Vax was a login prompt. The first (non DOS,OS/2,Windows) software
environment I really got to know well was Unix and then learning of
Lisp & LispM's. These days emulators are fun, capable and perfect for
most home users - I certainly would not have the room or power budget
for a CADR or PDP-10 or 11/780 in the basement! I respect those who
can but, alas, I'm not able to do that in my current rental
But I do have the room and enough of a toy budget to slowly put
together a classic PDP-11 system of the later /73, /83 or /93 type &
run the kind of software I'm familiar with on it. Might even try to
see if I can back port Franz lisp and to it from the 4.2 distribution
just to give myself a reason for it.
Ultimately I'd like to have a small collection of real classic
hardware - a Symbolics XL1200, a Vax (or Vaxstation) 4000 & a PDP-11.
I'll work on that last one for now and deal with emulation for the
rest :)
Thanks again to everyone,
William

Folks, I was an underbidder on the System/360 panel that recently went on
ebay.
This morning I received an obviously fake 'second chance' offer email.
The interesting part is that the sender had clearly done some research, as
ebay has not exposed your email address for many years, precisely to
prevent scams like this. Since my ebay ID is 'corestore_org' it's not too
hard to google and find an email address for me; they clearly did so, as
the email correctly associated my email address with my account name,
exactly as a genuine ebay email would.
I don't think anyone here would be taken in by such for an instant, but be
warned all the same; someone is being 'active' with scams tailored to our
interests. The email claimed to originate from 'ebay at ebay.joe211.info' and
sought a reply to 'jrengineer70 at gmail.com'.
EDIT a google reveals several other scam emails using this email address.
It never struck me before, but of course ebay doesn't even show underbidder
*account names* any more; they splash them with asterisks and display them
as x******x. Yet the scammer knew my full ebay ID, my correct email
address, AND the amount of my underbid. Someone *must* have cracked the
ebay database...
