I have some old ones I want to keep.

Depends on what you want to run?
IF you have a mix of DOS or earlier Windows (16/32 bit Windows) you
want to install Windows 7 (x86) 32-bit and install MS VirtualPC 2007
SP1.
This version supports all OS's including MS-DOS.
IF you use Windows 7 (x64) 64-bit Windows, you can only install some
32-bit OS's or 64-bit OS's.
Windows 7 (x64) will generate an error and won't allow you to install
VPC 2007 SP1. You can only install the newest version of VPC (2010ish)
and XP-mode.
Another work-around is to use VMWare or other 3rd party virtual
machine.
