I've got a Rockwell 65c02 CPU running quite well in my ][+ (64K with
language card), however, I can't seem to get ProDOS 2.0.3 running at
all. When I attempt to boot P8 2.0.3 from any device I get the splash
screen then the system locks up with a few garbage characters.
I thought perhaps the lockup was due to P8 2.0.3 requiring the //e
mousetext ROMs - further investigating reveals this not to be (A 65c02
CPU is the only requirement). I guess all I can conclude is that
there is a timing problem somewhere.
ProDOS v's 1.9 (and earlier) boot fine.
Any help with this problem would be appreciated.
In additon, I'm using a Videx 80-col card, Disk ][ controller, 16K
Language Card and a 128K RAM expansion card.
