Geohacker v1 is a utility that will allow you to change the serial number on your GEOS 1.2 or 1.3 OS boot disk.  In addition to that, it can also remove the copy protecetion from 14 other GEOS applications.

Full instructions are built into the program.

GEOS Flag Setter v1.0 by Joe Buckley (AKA Red Storm) is a utility that lets you set the flags that control whether an application will run on GEOS 128 or capable of 40, 80 colums or both.

GEOS Standardizer v1.5 - This program will allow you to standardize all your GEOS disks (presumably setting the unique serial number all the same) so they can be used with each other.

Thanks to Bruce Thomas for providing this utility.

Get It Write v1.0 by Joseph Thomas (September 1990) - This handy little GEOS 64 / 128 utility is a time & headache saver for users that put together geoPublish documents that may have several geoWrite files imbedded, because if any of those geoWrite files are missing or renamed, geoPublish will crash.  What this utility offers is the ability to open the geoPublish document from GetItWrite, which will then tell you the name of all the geoWrite files it will expects to find. You can also use GetItWrite to rename those geoWrite files internally in the geoPublish document in case you have newer versions or what not.  There is a geoWrite document in the archive with more details.  

Note - the files in this archive need to be converted to a GEOS format by running them through a GEOS program called "Convert".  I thought about doing that and re-uploading the archive, but I decided it's good for modern GEOS users to get practice doing the conversion, since most of the GEOS stuff you find around the net will need to be converted.  I'll do this conversion ahead of time in future uploads though.

TextView 128 by Holger G. Heimes is a text viewer for GEOS128 running in 80 column mode. You all know TextView for the 40 col. screen - this is the 80 col. counterpart. The screen shows 80x25 characters and all texts are shown in a non-proportional font. You can choose between an US and a german font and you can select files from up to four drives.
