C128 problem

[spaceman]

Hi,
I was at someones house a couple of weeks ago and he pulled out his C128. We hooked it up but all it would show was something that looked similar to...   @@@@@@@@   filling the entire screen ( I don't see the same character on my Macbook keyboard but it looks something like the @). If you held down the "Commodore" key and turned it on it would boot into C64 mode and appeared to be working. Is there a ROM chip or something specific to the 128 side? Is there anyplace that still sells parts for these computers?
Thanks

Did you ever get this working?

Isn't that what it displays when the system is trying to boot into 80 column mode, but the monitor is set to 40 column mode?

No, we took it apart and reseated the IC's, but it made no difference.
