Now, now, let's not pout and go into a snit just because you didn't get the free help we've all come to expect from this fine net. Why, after all, the question I'm about to repost never received any replies so far either but do you see me complaining about it? No, 'cause I'm here in Denver and you're in another country... >If anyone can suggest a comprehensive test for these chips out of the amiga >a may try that on the old ones before throwing them out. If one still works, >I could then keep it as a spare. I have a remotely similar problem with the 8520s on a used A-500 motherboard I bought. A brief (this time) recap of the story - I got the board in the mail, tested it, no go (nothing at all on the screen, 10 short blinks and one long blink then repeat on the power light of a keyboard connected to it). I swapped out most of the chips and they all worked - then I swapped the 8520s and got it to boot and operate normally. I then installed the A501 clone from my main machine, and it returned to it's previous behavior and stayed that way when I removed the A501 which is still working fine in my main machine. Obviously (?), both 8520s are now bad and need replacement. But is this symptomatic of a deeper problem on the board? At $15 a pop I don't want to feed what could be a CIA-eater... (so to speak) If you missed my earlier ramblings I plan to eventually build a multiplatform portable out of this - A-Max, PowerPC and Minix (or maybe Unix) as well as AmigaDOS. IF I can find a 5"-7" color RGB analog monitor (preferably multiscan), that is! . <<<>>> -- .---------------------------------------------------------------------------. |Ben Scott, professional goof-off and consultant at The Raster Image, Denver| |Amiga UUCP node domain: bscott@vila.denver.co.us Else: bscott@nyx.cs.du.edu| |FIDO point address 1:104/421.2, or call the Arvada 68K BBS at (303)424-9831| |"Don't embarrass us..."
