A Newton device with Newton OS 2.1 or greater, with 4 Megs of DRAM. (That means an upgraded MessagePad 2000, a MessagePad 2100, or eMate with the Newer Technology memory upgrade.)
About 2K free on the internal store.
There is a bug in the Newton OS that affects machines with 4 Megs of DRAM. This package installs a backdrop button which is a workaround to the problem.
Use the Newton Connection Utilities program that came with your Newton device to download the included package.
'61 Memory Fix is not needed if Avi's Backdrop is installed. The functionality of '61 Memory Fix is included in Avi's Backdrop.
First, credit where credit is due. Frank Wegener (wegener@travel-cs.com) of Travel Concept Solutions (http://www.travel-cs.com/), not me, is the person who came up with the NewtonScript code to fix the problem. Secondly, this is experimental! I don't guarantee that this will work on all -10061 problems. In fact, I don't guarantee that this will work on any -10061 problems at all. But it's worth a shot, and it should help.
THIS IS NOT A CURE FOR THE -10061 PROBLEM. Only Apple can provide that. This only alleviates the symptoms, and hopefully will keep your Newton from requiring a restart after a -10061 attack.
What happens is that, for some reason, on Newtons with 4 Megs of DRAM, the Newton OS occasionally loses track of a program. The program is still in flash memory, but it gets disconnected from the dynamic RAM. No one knows why, or how. Then, when the application is accessed, a -10061 error is generated. What '61 Memory Fix does is to try to reload and reset the connections to the packages in the flash memory.
To use it, you need to experience a -10061 error. When a -10061 error occurs, switch to your backdrop program and tap the status bar button labeled "'61". The fixing of memory can take up to ten seconds, depending on how many packages you have installed on your Newton. When the "'61" button returns to normal and the Newton makes a "ding" sound, the fix is done. Try whatever it was that you were doing again.
Some caveats: First, there are other reasons why a -10061 error might happen. The Fix only attempts to fix the infamous memory-mapping bug; it does not affect other reasons. Secondly, if your backdrop itself gets disconnected by the -10061 bug, you won't be able to access the Fix. You'll have to restart.
The Fix is harmless if accidentally selected.
