I recently upgraded my 28S to a 48SX, and I have a couple of initial questions
about how compatible my 28S is with the 48SX:
--
Does the FAST program (listed below) that set the clock speed on the 28S work
for the 48SX?
<<
RCLF
4 STWS
#Fh #FFF00h BAG
STOF
>>
Of course, I'd use the recently posted POKE program for the 48SX, rather than
BAG, but is #FFF00h the correct offset to poke the #Fh, or am I stuck in slow
mode? The 28S is quite a bit faster than the 48SX when the clock speed has
been increased like this.
--
Is it possible to somehow transfer my stuff on the 28S to the 48SX via the
infrared IO port? Perhaps I could send my programs on the 28S to the infrared
port like I was printing to the printer, and read and translate the data on
the 48SX end back into normal program format?

>Does the FAST program that set the clock speed on the 28S work >for the 48SX? No, the 48SX is already running at the "fast" speed and the speed cannot be changed. >Of course, I'd use the recently posted POKE program for the 48SX, rather than >BAG, but is #FFF00h the correct offset to poke the #Fh, or am I stuck in slow >mode? The memory map for the 48 is considerably different, the control registers now start at #00100h. There is no longer a speed control register. >The 28S is quite a bit faster than the 48SX when the clock speed has >been increased like this. The 28 may be slightly faster doing display operations when the 28 is in fast mode but other operations should be about the same. >Is it possible to somehow transfer my stuff on the 28S to the 48SX via the >infrared IO port?

I posted a program to do just that a few months ago. You will need a cable to download the program since it is binary and cannot be typed in. Preston

Not true; I have a couple of mathematical programs (simple prime number generator and a PI digit calculation program) that have nothing to do with the screen, and both run *considerably* faster (nearly twice as fast, I'd say) on the 28S. Also, when I run the FAST program on the 28S, simple commands like "edit" come up a lot faster; I wouldn't the operations that "edit" does when when it's coming up very screen-bound. -- /* Matthew T.

I have never come across this 'speedup' before, and I would like to know its limitations. Thank you! Michael C. Grant

From article <69@iconsys>, by mday@iconsys (Matt Day): > Does the FAST program (listed below) that set the clock speed on the 28S work > for the 48SX? No. The 48's clock speed is hardwired at the max speed you could squeeze out of your 28 through FAST. > Is it possible to somehow transfer my stuff on the 28S to the 48SX via the > infrared IO port?

This is done by the INPRT program contained on the disk that comes with the serial interface kit. -- This does not reflect the | Johann Schweigl | DOS? opinions of my employer. | johnny@edvvie.at | Kind of complicated I am busy enough by talking | | bootstrap loader ... about my own ... | EDVG Vienna |
