The microscope has a 'GPIB' interface for control and data transfer. If we could get an adaptor, we could transfer images and control it from the PC even with fancy new features like image transfer and special modes. There is already software written for this microscope (in Labview = Windows) so we could either get the adapter and a windows PC with labview, or adapter and rewrite e.g. in python based on the code we have in labview. There is already a (non-public) project for laser control in python which we might be able to use, @lorxor knows more.
in progress...
Replace the floppy drive in the microscope with an SD card emulator. We would need to make sure that the emulator is compatible with the interface and the 'old old' 720 kb standard. (Or just test one and send back if it does not work.)
Costs: about 20€
Difficulty: Easy
The laser controller for the visible red laser does not save settings anymore. Inside there is a memory chip with a built-in battery that needs to be replaced. Right now all the settings including basic configuration need to be entered manually when using the red laser which takes a lot of time.
Cost: 10€
Difficulty: Easy
The red laser connection cable is makeshift and needs to be set up manually every time and is fiddly. Would be cool to make a proper connector/cable.
Cost: 10-20€
Difficulty: Easy
If we want to use the red laser during 'normal' xHain hours (e.g. not locking everyone else out), we need an interlock at the door and possibly the window and a warning light over the door. We would need to install a switch and a warning light and run cables to the laser controller.
Cost: 100€
Difficulty: Medium
Basically reverse engineer the connections between the old PC and the microscope and add a new PC. Transfer what is useful (e.g. scanner driver) and add some means of analog-digital converter to get the signal. Write some software to actually display and control the microscope.
Cost: ???
Difficulty: Ultra-Hard
Starting point for software (python)
