How does an NTSC type program look on a PAL Amiga? I'd like to be able to send a collection of PDware to a friend in Finland. Are there complications? Alan Whinery whinery@hale.ifa.hawaii.edu

The programs will not fill the whole screen but unless it's videoprgms that should be no problem. Jorgen

Who's going to be thr brave sole and post a hardware hack for the 500 or 2000 (both preferabally) that lets you have a physical switch for ntsc and pal?? C'mon!!Be brave! Do something useful for your countary! email *IS* prefered!!! but... hey.. cant expect the world! mail: jeremym@brahms.udel.edu

They just doesn't use the lower part of the screen since NTSC has
fewer screen lines than PAL.
No complications.

While this is basically true there are protection-schemes that will make it impossible to run software on both sides of the pond. These are usually as poorly written as the disk-protection schemes making the program impossible to run on a number of machines :-) Sorry to be a spoil-sport but as long as it's PD-stuff there is nothing to worry about.

Usually the only problem is that since we in Europe have more pixels on our screens (ex. 640*256 vs. 640*200) there is a big blank space on the bottom of the screen. If the program uses only CLI and doesn't start it's own window/screen, no problems usually occur. I speak for myself, but I never use programs which can't adopt to PAL and leave 20 % of the screen blank. My WorkBench size is now 736*284, which makes the NTSC problem even worse. Also you should notice that the aspect ratio of pictures will become wrong. >Alan Whinery >whinery@hale.ifa.hawaii.edu -- Henrik 'Leopold' Herranen Internet: h112706@lehtori.tut.fi Snail Mail: TTKK/Paarakennuksen neuvonta/PL527/33101 Tampere/Finland "I don't need no arms around me, I don't need no drugs to calm me" - PF 1979

Thats not strictly true ! I have a copy of Tetris that switches to ntsc, the screen stretches vertically and the top and bottom are off the screen. The machine has to be re-booted to restore it to normal. +-=-=-=-=-=-=-=-=-=-=-=-=-=-=+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-+ | British Telecom Fulcrum | name : Simon John Raybould {^.^} | | Fordrough Lane | path : sie@fulcrum.bt.co.uk \~/ | | Birmingham +-----------+--------------------------| | B9 5LD | // | AMIGA B2000 | | ENGLAND | \X/AMIGA | Lattice C V5.05 | +-=-=-=-=-=-=-=-=-=-=-=-=-=-=+=-=-=-=-=-=+=-=-=-=-=-=-=-=-=-=-=-=-=-+

Here is a PAL/NTSC switch setup I developed for those machines with a BIG FAT
AGNUS...
How to install the NSTC / PAL switch into your Amiga 2000
===========================================================
This modificiation will work on a default NTSC or PAL A2000.
First off take the cover off your machine and remove the drive and
Power supply chassis ( disconnect the power supply and the disk
drive ribbon cable from the motherboard...make sure you remember
which end of the cable goes to which pins!!! ). Then remove the
whole unit from the machine and set it aside...
A. Now look for the FAT AGNUS chip on the motherboard, it should
say FAT LADY near the chip....now check the number on top of
the chip, You MUST have the new 1 Meg Agnus (Super Agnus part
#8372).
B. Move motherboard jumper J300 from the factory default position
of pins 1-2 to pins 2-3. This jumper is located under the power
supply.
C. Locate jumper PADS (no pins) labeled J102 and cut a trace
between the 2 pads. BE CAREFUL!! The pads are located right
next to the AGNUS on the left hand side ( if you are PAL
default no need to cut the trace..since PAL is already cut)
D. Mount a SPST switch in a convient place on the outside of the
Amiga, perhaps next to the power on LED.
E. Run 2 wires from the switch to the 2 pads of J102 (1 wire to
each pad).
That's it. With the switch closed (on position), you'll boot in
NTSC. With the switch in the open position (off), you'll boot in
PAL.
NOTE: Most monitors will only require a minor adjustment in vertical
sync and/or size to work in this manner. Composite monitors will
NOT work.
You must re-boot for the change to take effect, since the jumper
is only checked at power-up. If you have problems with Genlocks
that go in the video slot, run a SPDT switch to the J300 jumper
to allow you to switch timing between Power supply and Video
section sources.

My BBS is down. Sorry, I don't feel like editing.
You do not need to change the J300 jumper, it's just that if you don't, SI
will report 50hz video, PAL, but 60hz power supply. IF you have J300 changed,
it reports 50hz on both (true PAL), however you don't REALLY run at 50hz, you
just pretend...
There is also a bug in the OS which causes the opening screen to be NTSC
dimesnions on a PAL display, but this doesn't happen all that much. If you
leave your opening window open (it still is 640x200, not to be confused with
opening screen, 640x256) there is a program I wrote that will change it for
you. I would FTP it or whatever, but I don't know how!

I would also like the plans for the NTSC/PAL physical switch if someone is
BRAVE enough to post one on New Xanth, or sending me E-Mail.
