HP-28S Speed Up!

I've had a lot of visitors but few comments! Let me hear from you! Email me at:
The program below will speed up version 2BB of the HP-28S to twice itís normal operating
speed. Pressing the ON key at any time will return you to normal operating speed. Note: If you
do not key in the hex numbers in this program absolutely correct, then it may very well wipe out your HP-28Sís memory and give you a memory lost! Be careful.

Thatís it. Anytime the program FAST is executed, your 28S is running at 2X speed.
Now for the disclaimers: This is presented solely as an item of interest to HP-28S users. Although many people have used this for a long time, you do so at your own risk. I accept no responsibility for anything that happens.
