Yesterday I received a real treasure: a complete TWIN system including a full set of documentation and lots of floppy disks! I am really excited about this machine, especially since it came with the TWICE interface box and cables. I now finally have a complete system to work on. The system has been stored in an attic for 30 years; not only does it deserve a thorough cleaning but the capacitors in the power supplies probably need careful handling or replacing.
It will take many hours just to make an inventory and catelogue the hardware and documentation, and to create images of the diskettes. A quick glance revealed that it has at least the original disks for SDOS 2.0 and SDOS 4.0. You can expect scans of the documentation and disk images for download on this website soon.
