I have an old famicon game system that is PAL-compliant.
Other than a PAL/NTSC converter or PAL TV is there any way of
hooking this up. ?
I do have a kaleidoscopic collection of monitors as well as
several VCR tape decks and a JDH Videomate external VGA/TV
adapter which allows me to use my NEC multisync as an all-
purpose viewer. It has an H-Phase pot whose response on the
monitor is a shift to the side of the display and otherwise not
causing any picture distortion. I recall on my Atari there were
programs that shifted from 60mhz to 50mhz and allowed you to
play PAL formatted games, but in this case there is no computer
intervention with the JDH. It is a straight-thru switch.
I don't consider this OT since the PAL/NTSC is a problem for all
collectors who are internationally-connected in this media.

An A/V Mac might do the trick. My PowerMac 8500/180 is a A/V system and it
can handle either NTSC or PAL inputs and display them in a window on the
desktop.

If I remember correctly, the format difference between PAL and NTSC lies not
only in the difference in the vertical refresh rate but also in that the
NTSC format is based on 525 horizontal scans per frame, while PAL uses 625.
I'm not at all sure about whether PAL interlaces in the same way as NTSC
does it, and, in fact, I'm not sure that they do that at all.
Scan rate conversion is not at all a trivial process, to wit, boxes that did
that between the desired NTSC format and the somewhat unusual high-frequency
format used by the SGI stations on which high-res graphics were processed
when I was involved in that sort of thing, cost several tens of thousands of
taxpayer dollars.
If you can find convertor of some suitable form, perhaps one of the popular
video processor boxes that goes with the MAC or AMIGA for audio/video
processing, that's your best bet.

I have a BBC Model B, modified for US power. It spits out a 625-line
picture somewhere around (US) UHF TV channel 35 or so (haven't fired
it up in years,though).
Since the output is 625-lines (normal US TV is 525 lines) some of
the top and bottom of the screen is missing. Also since PAL
encodes color differently from NTSC, the picture is black and white...

Hi
Recently we had a computer that was setup for PAL ( B&W ).
We tried it on one of those Sony monitors that has a
select for everything. We never were able to get it
to work. Latter we tried an old black and white monitor
( well black and green ). We were able to adjust the
vertical and horizontal enough to get it to work.
I guess it really depends on what you expect. I think
the Sony may have been looking for the color burst
or maybe the audio to lock onto. The computer we had
only produced video B&W out.

Well, the B&W signal is (with an exeption of the
VerticalF/Lines ratio) the same for both - and since
the resulting horizontal frequency is (almost) the
same, most B&W monitors are able to display NTSC and
PAL (or better US and European B&W) with only minor
adjustment. A good buy here is an Apple /// screen.
Simple, ad still fairly available.

Apart from the obvious answer 'to a PAL monitor', I can't think of any
way of viewing the signal which doesn't involve a device that directly
displays PAL encoded signals (TV or monitor) or a device that conerts
PAL to something else that you can display (converter to NTSC or RGB
or...)
I am going to assume that the signal is the European PAL format (there
are other PAL standards, but I've not seen a computer that uses them).
The main differences between that video signal and the one used in the
States is :
Europe USA
# lines 625 525
Vertical Freq 50Hz 60Hz
Horiz Freq 15.625kHz 15.750kHz
Colour encoding PAL NTSC
(Subcarrier) 4.43MHz 3.58MHz
So to produce a genuine USA TV signal from a European one, it's not
just a matter of converting the colour encoding (which is a relatively
simple process -- there are plenty of RGB <-> TV colour encoding chips
about for all the common standards), but also a scan rate conversion
(a lot harder).
But you can probably get an RGB monitor in the States that can take
RGB signals at European rates (they are available in the UK -- in fact
most TVs over here will do that). So you'd then need a decoder from
PAL to RGB -- which is a fairly simple circuit, but probably not one
you want to design yourself...
I do have a kaleidoscopic collection of monitors

Well, those of us who collect mostly largre machines that either have

(minicomputers) don't have this problem too much :-)
