I used VMSpc which is typically loaded on a laptop and installed it on a mini desktop. I did not want to encumber either the dash or the entrance walkway with a laptop installation, even a mini notebook, so I found a way to install a mini desk top PC. The Acer Aspire 1600 is a full feature desktop running windows XP. It measures approximately 7” x 7” x 1”. I purchased this unit and a Xenarc 705TSV 7” touch screen monitor to be a single software dedicated computer to run only Silverleaf VMSpc. This PC and monitor will run on 12VDC. There were some installation issues but all were overcome. So far VMSpc is operating normally.
