Apple IIgs booting/monitor problems

["Gabriel Androczky" <p0531d0n@freemail.hu>]

Hi!

I just got an Apple IIgs with two floppy drives (1x3,5" and 1x5,25"), a
keyboard, a mouse and a 12" RGB monitor.

I quickly ran into two problems:

1. The 12" Apple RGB Display does only display some running blue pattern. I
suppose this monitor is not meant to be used with the IIgs. Which one then?
What's the difference?
In the meantime, I hooked the IIgs to my TV with that RF modulator output,
but the colors are shifting and the text is only readable when colors are
dimmed on the TV set.

2. I downloaded a 6.0.1 OS disk image from Apple (first 2 of the 7-disk set)
and made them onto floppies (i've put some adhesive tape over the HD hole on
the floppies) with DiskCopy on my Power Mac.
When I boot the GS with that floppy in the drive, it says "UNABLE TO LOAD
PRODOS"....
What does that mean???

Please help!

Thanks,

Gabriel
