- Here is the program to speed up the 28s. Store it under the name SPEED.
- A few things to remember: power consumption varies with clock speed.
- Doubling the clock speed will certainly increase your battery drain. On
- the other hand, slowing the clock speed will reduce battery drain!
- Changing the clock speed will change the beeper freqencies, as well as
- the results of any time programs you may have (there's a program in
- Mier-Jaedjowskowicz (sorry if I slaughtered the spelling) book on hp28
- insights to show the time using the internal system clock).
-
- I've double checked the accuracy of this posting, but keep in mind that
- memory losses always strike when you least expect them, so write down
- those important programs first!
-
- To use the program, put a number between 0 and 15 on the stack and
- execute the program. 7 corresponds to normal speed, and 15 to 2x speed.
- Here it is:
-
- << 'SPEED' -> s n << PATH RCWS 64 STWS s R->B #Fh AND #1000000000000h
- * #C600302331DFFBCh OR { #E60D51FFF00F1h #C808461241131h } + HOME n
- RCL SWAP n PURGE n STO #DFFB7h SYSEVAL n STO STWS ->STR 3 OVER SIZE 2
- - SUB STR-> >> >>
-
- remember, you must save the program under the name SPEED.
-
- Also, THIS PROGRAM IS NOT FOR THE 48!! dont try to run it on one.
