Propeller in the wild

The Chameleon uses a PIC24 MCU running at 40MHz as the master processor, and a multi-core Propeller chip as the media slave processor.

Re: Total hardware newbie

:D Welcome to the group. I think Vince would still stand by what he said a few years ago. "To show my dedication to you getting your replica 1 working: If you can not get it running I will look at it for you if you want to send it in. All I ask is that you cover return shipping charges. I reall...

Re: BASIC returns zero instead of a decimal place number

OK this must be the page you saw. http://simonowen.com/sam/apple1emu/ Notice, about line 12 of the page: Software For your convenience, the emulator is pre-loaded with the following software: * Tom Greene's port of Applesoft BASIC at address 6000 Enter 6000R at the monitor prompt to launch Applesoft...

Re: BASIC returns zero instead of a decimal place number

Sorry about all the posts but this peaked my interest, thanks George for the motivation. Here is a good link to doing math in micro controllers.

Be grateful for modern computers and software, floating point the hard way in software.

Re: BASIC returns zero instead of a decimal place number

Here is a great article about getting "Microsoft Basic" to work on the Apple II as "Applesoft Basic".

Re: BASIC returns zero instead of a decimal place number

Aha here it is. "Integer BASIC, written by Steve Wozniak, was the BASIC interpreter of the Apple I and original Apple II computers. The most frequently cited flaw of Integer BASIC was, as one might expect from the name, that its variables were all 16-bit integers and it was very difficult to wr...

Re: BASIC returns zero instead of a decimal place number

:oops: I went in the wrong direction. As a continuation of above you can use a fake scientific notation. I might be missing some commas in there 10 FOR X = 1 to 10 20 PRINT "1 / ",X," = ",100/X,"X10-2E" 30 NEXT X 40 END http://en.wikipedia.org/wiki/Floating_point

Re: BASIC returns zero instead of a decimal place number

I am not sure I do not have mine yet but this should be an integer basic and will only show whole numbers not any decimal points. To fake it you multiply your original number by 10 or 100 if you want 1 or 2 decimal places, do the math, then you have to divide by what you had multiplied by and subtra...

Re: CP/M?

This might be a version of CP/M that will help with getting it on the Altair 8800 micro. It is for the Epson PX-8 Geneva a portable that runs CP/M out of ROM. :mrgreen:

Up and working with Sharp 42" LCD TV

Great job Vince works great with both a 17" LCD monitor and my sharp TV either small picture in center or stretched to full screen. Page 8 and 17 are missing (QTY2) for 10k resistors. Will do testing with various computers.
