On the project.

I have two iMac G5s: one single core with 2G RAM, the other dual core with
512M RAM.
What is the maximum RAM that each will be able to use under FreeBSD?
The project will be brltty on PPC64 and others that use a bootloader.
PPC64 will be the initial setup.
I have read through the config/configure file of the brltty source code.
The open firmware references in the FreeBSD PPC64 were also read.
Before I restart on the project, here is the basic information:
Brltty configure will need to be rewritten to include the open firmware
references.
I have never used the FreeBSD version of the device tree referenced to
as the "flattened device tree." The only use/ reference/ experience was
directly accessing open firmware from the forth prompt.
Currently, I have no braille devices here due to an extremely limited
income. I'm going to do a port build and not a package setup of both
computers. More RAM will need to be purchased. Because the
computers are at someone else's place and that I need to purchase
my own mobile dedicated network along with wireless dongles, this may
take some time.
I will inform you (pl) again when the next step or so is done.
