<p>Created a simple page on this software</p> <p><b>New page</b></p><div>VMU2PC is a collection of software allowing the transfer of data between the VMU and a PC. The package contains two programs, Serial2VM, written by Soeren Gust, which uses a serial port with a Atmel microcontroller to convert the logic from the 5v of a typical PC to the 3.3v logic of a VMU. Secondly, VMU2PC, written by John Maushammer, which uses the a parallel port and a custom cable to reduce the voltage for the VMU. Gust&#039;s software was used as a basis for Maushammer&#039;s approach. You can download it here.<br /> <br /> == Serial2VM ==<br /> This approach uses an Atmel AT90S8515 to convert the synchronous serial protocol from the VM into the normal asynchronous serial communication. Sadly the firmware required to create such a cable has yet to be found and likely lost to time.<br /> <br /> == VMU2PC ==<br /> This approach uses a custom made cable to transfer the data via a parallel port. You can read about how to create the cable [https://web.archive.org/web/20030210032641/http://www.maushammer.com/portprobe.html here.] The program however it relies on processor loops for timing, which might not be very useful on modern hardware.<br /> <br /> == Further Reading ==<br /> <br /> Maushammer&#039;s page on VMU2PC<br /> [https://web.archive.org/web/20030207031204/http://www.maushammer.com/vmu.html]<br /> <br /> Gust&#039;s main page on VMU<br /> [https://web.archive.org/web/20021207224951/http://soeren.infoserv.de/vm/Index.html]</div>
