Re: A little power circuit explanation please

2017-08-22 Thread Rob Doyle via cctalk
It's a little switching power supply.  It steps up the 9V input voltage 
to something a few volts greater than 12V to feed the 12V regulator.


If your 12V is correct, it is probably working.

Keep an eye out for a Night Owl 7" LCD Security monitor. It has dual
composite inputs and is a great companion for my //c and is also
exceedingly convenient for taking to meet ups. Much easy to lump around

You have good taste. According to the manuals, that's the lower resolution

Sony made an excellent, small colour monitor, the PVM-9044QM. It's quite light
and portable. The reason I like it so much is that it will take just
about any TV
rate video -- composite colour video (PAL, NTSC, NTSC-4.43, SECAM), S-video
(on any of those standards), so-called 'component video' (Y and 2 colour
difference signals), and RGB. At US or European scan rates. It can run off
the mains (100-240V) or 12V DC (or I believe internal batteries, but I don't
have them).

It's a Trinitron CRT (not surprisingly) and the unit is well made and not too
hard to work on. You can get the service manual on the web, but be sitting
down when you look at the schematics, it's not simple.

The only problem is finding one

Re: Wanted: small composite CRT monitor

I do have at least one Apple IIc monitor around here, the small
green-screen as originally sold with the machine. Not sure where you're
located, but if it's practical, I'd certainly consider taking a trade for
it.

As for generic older crt, I am very fond of my BMC green screen, ca. 1982
or so. It's built on a 12" b TV platform, you can see all of the
vestigial features of a television case. Pretty sure it's just a standard
b TV, rebadged and fitted with a fairly hi-res green crt and no tuner.
Takes a single comp. video into an RCA on the back panel which previously
held some controls or possibly the antenna base.

I've been meaning to add a speaker and small (LM386?) audio amp so it can
do sound as well. Should be easy, there's a speaker mount pattern already
in the case and it seems that one should be able to derive an acceptable
+5-12V rail from one of the low-voltages on the board.

My only gripe is that the thing lacks a pilot lamp, and lacking input, you
can't tell if the power is on. So I stuck an orange LED on the front panel
with the old zener / 1n4007 / 10K trick.

It is part of a switching power supply to boost the 9VDC input to 13.7V or 
greater so that the 78L12 can regulate it down to 12V.


L1 is dual purpose; it provides feedback to the boost switching regulator 
oscillator (the tap) and is the main inductor for the boost supply generator.

Late last year I picked up a Sony PVM-9041QM 9” ex-broadcast monitor for not 
much money at all, it sits nicely on top of an Apple ][ and looks excellent 
with a pair of Disk][s stacked next to it. There MUST be TV studios around your

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?


Searching for a Sequent

2017-08-22 Thread Ian Finder via cctalk
Reiterating my yearly wanted post for a Sequent Symmetry of any kind. This
is the first system I ever got root on- I'd love to find one some day.

If you have any leads, please let me know.

Thanks,

I wish Ken would put up the code for his 3mbit gateway on the BBB on github.
He didn't want to do it until it was reliable. The nice thing about that
solution is you don't need 3mbit transcievers. I found another box of a couple
dozen of them, but that's probably the last stash of them left in the world.

Maybe you can get one of the LCM 3mbit PCI-e cards from LCM?





HIRING! Diablo Model 31 Disk Drive repair for Xerox Alto

2017-08-22 Thread Nick Allen via cctalk
I am almost complete in fixing my Xerox Alto (been a 7 year journey, 
have the power supplies, CRT, and boards all working). I can get the 
Alto to run the microcode to boot, but my disk drive is not working so I 
can not boot (looking into Network boot with Carl, but this is not yet a 
possibility).   I am by no means an expert in these old disk drives, and 
desperately need an expert to help.  I am looking to hire someone who 
has extensive experience repairing RK05 style disk drives, and is 
confident they can not only repair, but can also verify and test the 
disks to ensure they are reading properly.  If you would like to be part 
of the story of getting this Xerox Alto up and running, please email if 
interested.
