Chances are your computers were not just upgraded to 800K RAM; there is no such configuration for any Macintosh. The DISK DRIVES might now be 800K disk drives (allowing you to use double-sided disks) rather than 400K drives. What matters for your purposes is whether you have 512K of RAM or 1Mb. Or, of course, 128K, if your Macs are REALLY ancient. The way to determine this is to boot your computers with any startup disk, then, while in the desktop, choose About the Finder from the Apple menu. There should be a notation in the resulting window telling you how much memory your computer has. Vaccine is fully compatible with any System whose Control Panel desk accessory lets you choose between multiple Control Panel Devices (cdevs) such as "General," "Monitors," "Mouse," etc. The best way to determine whether your computers can run such a version of the System software is to try startup disks with various System/Finder combinations. See your dealer for assistance. Mark H. Anbinder
