System Requirements:
--------------------------------
- IBM PC or compatible
- DOS 3.1 or later
- Standard RS232 serial port

Note:
--------
Software requires an IBM compatible PC booted to DOS with an RS232 serial port (it will not run reliably in a DOS window under any Windows version, or using USB adapters, etc.). This software was originally released for 386-class PC's and will likely require a slow (486 or older) PC with any internal and external CPU cache disabled in BIOS and/or with a software utility. For newer PCs running NT, XP, Vista, Windows 7 etc., as with most legacy radio software the PC will need be booted to DOS using a CD or floppy drive, etc.
