Be very carefuly! It is easy to kill your HP! There is absolut no
warranty with this circuit and your HP48SX. It may kill your HP after
some time. I can only say that it now works fine for me for two
months.

0. Watch in you wallet. Is there enough money to buy a new HP48? No?
Stay away from this! Yes? Try it.

1. Build the circuit. There ist no PCB! I had build it in the
air. Looks terrible but is very small. A good Irish whiskey may
help you. :-)

2. Put the unused inputs from one 4011 to ground!
 
3. Test it with your ossi. You should see 60-65khz on the output. With
a magnet you can switch to 32khz.

4. Connect the circuit to the HP48SX. It should work :-)

5. Enjoy the new way of live.

6. Send me a mail about your success or die on a very cold and unhappy
place! (olaf@criseis.ruhr.de)

Without the magnet the HP is running around 4Mhz. With the magnet he
is running at normal speed. Use the magnet to download your
software. You can't download the software in turbomode.
