I run it on an old IBM Thinkpad with a Pentium II 400 MHz processor and 256 MB RAM. This is a laptop that is dedicated to running an Icom IC-PCR1000. I use the discriminator tap of the 1000 for UniTrunker, which runs on the same computer, in conjunction with the computer control software for the 1000. When the program opened in a small window I had bizarre "scrolling" display results. When I open the program to full screen size (which still does not completely cover my 1024 x 768 screen, that problem disappears. I have no issues with zipping around the screen cursors and can save text ID's without a problem, so the program does work fine on an older computer for me, anyway.
Greatly looking forward to the next version. Thanks, Rick.
