The problem I'm having in my internal 1571 right now appears to be an intermittent electronics failure. I don't know the true cause and I'm trying to find out if its related to heat build up. Just a guess, but it might be thermal creep or something insidious like that. After power-up reading the error channel yeilds a trashed status message with garbage characters. "DIRECTORY" gives a trashed listing as well. Seems to happen mostly in C-128 mode so *might* be related to burst protocol (something I don't know much about.) So far I don't see any problems in C-64 mode. Does the 128D depend on the cartridge port to be open for proper air circulation? I wouldn't think so, but with my SuperCPU the port is plenty blocked. Anyway, the system fan is running fine so heat build-up be minimized. I never had this kind of problem with my external 1571. Last time I saw this kind of problem on a 1541 it was due to a failed voltage regulator. ===== Get a FREE 6Mb webmail box from go6502! - http://www.geocities.com/profdredd __________________________________________________ Do You Yahoo!?
