  Cache Control

In most cases your Tiny Turbo XTra will operate flawlessly with
the cache memory on.  Some non-standard expanded memory
systems and some older speed-sensitive, floppy disk based copy
protection schemes will not work with cache memory.  Further-
more, some systems may not boot with cache on.  For these
reasons the Tiny Turbo XTra has a toggle switch to disable the
cache memory.

❐

  The Cache Switch

For booting in certain non-IBM PCs, a toggle switch cache
control is provided.  This switch is located in the upper position
of the rear panel.
