SqliteQuery (Mac)
Description:
SqliteQuery is a management tool for SQLite databases.
You can edit and maintain existing databases or create new ones using this tool.
SqliteQuery comes with the compiled SQLite database library builtin.

It can also execute single or batch SQL statements. The result of SELECT statements is conveniently displayed in a tableview.

The SqliteQuery user-interface is separated in four parts.
1. setting the database path (defining a not existing path will create a new database - you will actualy be asked before creating it
2. input of SQL statements
3. showing result of SELECT statements in a tableview
4. showing a log output

Requirements:
SQLite database library has been compiled on a Mac OS X 10.3.9 system.
So in general Mac OS X 10.3 and Mac OS X 10.4 (I work on Tiger) is supported.
Mac OS X 10.2 should work too, but this is untested.

With version 0.6.1 of SqliteQuery Mac OSX 10.3.9 is required at minimum.

Licence:
SqliteQuery is freeware.

Sysdiag (Amiga)
 
Description:
Sysdiag is primarily a RAM testing tool. However, it can also show available expansions of your Amiga.

Sysdiag can shows information about you memory and hardware of your Amiga.
For memory testing it uses algorithms like:
- custum address test
- own address test
- walking ones test
- moving inv (8bit) test
- moving inv (32 bit) test
- modulo x (8 bit) test
- modulo x (32 bit) test
- bit fading test

Start Amiga without OS and execute from Amiga Shell to test as much memory as possible.

Some of the tests are executed twice (memory cache enabled and disabled).
The bit fading test can take much longer. It tests if the memory is refreshed and if the bits are stable.

Requirements:
It has been tested on AmigaOS 3.9 but should work as well on AmigaOS 2.0 and above, maybe on OS 1.3 systems, but this is untested.

Licence:
This peace of software is released under GPL.

Download:
I have made a archive with all source files including makefiles.
There is a compiled version for 68020 Amigas in this archive, too.
