Hej Allihopa... I just received a C128 (220v PAL) and when I powered it up it just displays garbage on screen. All it displays is some random graphics (not really characters, but rather strange patterns) with different text and background colors. And all this is flashing and changing. And it won't go to C64-mode when I hold down the C=-key while turning the power on. Anybody got any ideas as to what may be the problem? I got the following from Ray Carlsen's trouble shooting/repair-site (http://personalpages.tds.net/~rcarlsen/cbm/C128-IC.txt): U11 315012-01 (8721) PLA (Programable Logic Array) No bootup in any mode. In 40 columns: blank screen, white screen, light blue screen (no border), random checkerboard pattern or flashing "garbage" characters. U18 390059-01 CHARACTER ROM No characters. Startup has border, but "garbage" where characters belong, or entire area inside border just lines or blocks. Could that be the problem? With the flashing I would think that it is the U11 problem? What dou you think? Do you think it can be fixed? Any hint to how? If it is the PLA that's faulty, where can I find a new one? And how do I make sure it really is a bad PLA? // Mikael ----------------------------------------------------------- Mikael Holm email@example.com <FONT SIZE=1 FACE="Arial">_______________ Please note that this message may contain confidential information.
