Charon-VAX offers a freeware version now for OpenVMS users as well as Fedora Linux users. But, I am going to use SIMH. I'll just get a version of OpenVMS for hobby usage. The problem I have is more so with my wife than really space. I already have a lot of stuff in my house and adding yet another system will just make matters worse. The emulation route is more suited for me. so every app its own copy off disk every time. This sounds more like what I want to do. I am in the process of re-writing the iserver transputer host communication application to be a bit more open. Currently, all the drivers are linked into the application which makes adding new driver support a pain. I want to dynamically load the library like this: |c0t5l0|T|localhost|/dev/c0t5l0|transputer.so|||| So, when the application configures itself for c0t510, it will dynamically load the file transputer.so and use the device /dev/c0t510 as its resource (this is NOT a real example). Is this possible? The library will have the standard INMOS communication API present (OpenLink, CloseLink, etc) Thanks, Ram
