Speedcache Plus
Larry,
Speedcache+ is made by Future Systems Solutions (219) 824-4963 in Bluffton,
Indiana (they also wrote Norton NCACHE and Windows Smartdrv).
It can be purchased for 79.95 (plus shipping) from JDR Microdevices at
1-800-538-5005.
I have been using it for 4+ weeks and it seems to work fine. If you need
to cache a CD ROM it works really well assumming you can give it some memory
to work with.
