Quote: What most likely what has happened is that a bad bit has been loaded into the EEPROM on the HC11 and this is causing the HC11 not to find the memory location were the external update program is located. What you have to do is clear this memory location which requires one to open up the Autostar and jumper two pins on the HC11 to ground to force the HC11 into special Bootstrap Loader Mode and use a program that allows one to clear the memory. If you go to the yahoo group ROBOSCOPE, in the file section is "Autostarrevival.pdf" that explain step by step on what to do to bring your Autostar out of it's coma. - Dave

Quote:There are 7 flavors of Autostars (counting the Starfinder and 494) The 495 and the original 497 CANNOT be upgraded beyond ver. 4.3EG. Firmware ver. 5.0 and above are only usable for the Autostar 497EP (Audiostar). Attemping to use these firmware versions with the 495/497 will brick them.I'm not aware of any easy cure for a bricked Autostar. There may be a low level protocol to reset the main processor by fiddling with the pins, but it's not for the faint hearted.The Autostar II and III are dumb control boxes. The circuitry normally found in the 497/497EP is located in the mount, so the mount has to be upgraded. The LX200, LX400 and LS models use various methods to connect to a PC for the upgrade.
