Currently the Autostar updater is a Windows-only application, although a Java application is planned that will run on Macs, PCs, and Unix workstations.
In order to run the current updater using a Macintosh you will need either Soft Windows from Insignia (now discontinued) or Virtual PC from Microsoft (formerly from Connectix).
I used the serial adapter that was included with my Ricoh digital camera.
This adapter converts from the DB-9 on the Autostar adapter to the standard Mac mini-8 serial port.
But the handsets are getting difficult to source these days, at least in the used market.
Jump to the Start of Today's Update (please wait for the page to finish loading). Shown in the photo on the right are the items that are included with the #505 Connector Cable Set from Meade.
Went on the Meade site and it has an image of a controller hooked up to the ETX with another cable going to the computer.
Errors lead to bricking which can only be repaired with great effort.However from what you have said it sonds as if the handset recognises the scope and if so then that prevents that idea.Only say this as it seems I can use a 497 on the ETX70, even though the ETX70 is not in the 497 handset. The place to go search is the now old Weasner site for imformation.The 506 connector cable set can then be used to update the controller, or connect to a computer if desired. From the replies above it sounds like the Goto function is only available with the #497 for ETX models ?? 2) The 494 Autostar *can* be updated with the 506 cable set. 3) The only scope that absolutely requires the 497 Autostar is the LXD55/75. If you don't do custom objects and tours and all that, it's no different than a 497. New or used, a 495/7 will cost near 0 *if* you can find one in good shape.All others are supposed to be interchangeable with 494s, 495s, and 497s. -drl OK, found out from Meade - regardless of firmware, the 494 will *not* operate anything other than DS and ETX 60/70/80 scopes.Once VPC was setup and the updater installed and running in Windows98, I turned on the ETX and followed the instructions in the supplied cable set manual.
