Re: "International NTSC" Apple IIe motherboard?

[heuser.marcus@freenet.de]

Additional info:

An Intl.-NTSC-motherboard may be fitted with a crystal and an IOU-chip
from a 60-Hz (US) NTSC-board - turning this board into a "real"
NTSC-board with the differences pointed out by mdj.

In fact I did this to get a french video card to work with 60 Hz -
which it did, until it stopped working ;-)

However: Appropriate care should be applied when desoldering the
50-Hz-IOU-chip (its not socketed).

Is it worth it? IMHO: No.

If you have a 60-Hz-IOU chip and the right crystal you probably have a
working NTSC-board.

At the moment I use a 1984-US-motherboard which works best and gives me
what I want most (on my current NTSC-capable TV-set): The closest
approximation what a games developer (or gamer) saw on his screen under
the best circumstances in the beginning of the eighties.
Because I wanted to use this board in a German case I had to tinker
with the cables (keyboard and speaker) and to get German characters on
screen I use the German ROMs and a nice adapter, which is sold by
GSE-Reactive.com. Highly recommended.
