Jumper and Switch Setup
Before installing the Tiny Turbo XTra in your computer, make
sure that the jumpers and switches are set for your configura-
tion.
The factory configuration of the Tiny Turbo XTra is as follows:
No 80287 Math co-processor installed.
Timing and compatibility is set for IBM PCs and
most compatibles.
Installation in any slot except J8 in the IBM XT,
J8 is the closest slot to the 8088. It is not a normal slot,
IBM intended it to be used for connection to an expansion
chassis.
You can change the configuration by moving jumpers. Their
functions are given in the next sections.
To install a jumper, the black plastic sleeve must cover two
opposite pins with a pin in each hole of the sleeve. If it is hard to
get a grip on a jumper, try using a small screwdriver.
