Hi,
I recently purchsed an Apple IIgs - but it had the unsopported ROM0-Version. So
I wanted to upgrade - I got the ROM1-Roms from a friend and they work fine in my
GS with System 6.0.1 - now I wanted to copy the roms to an eprom - I guess i has
to be a 27C256 - I used one with 150ns - I burned the eproim verified it and put
it in the GS but it does not work. After showing the blue-screen with the
copyright and version note it refuses to boot from HD and FD (that is possible
with the original ROM1 from my friend in my board).
Can anyone help me?
