Speed-SWitch v1.1 Mega STE 1992-02-11 -------------------------------------- Welcome to Speed-SWitch v1.1. The idea behing these programs is to provide an easy way of switching between different speeds on the Atari Mega STE computer. Together with your Mega STE you got the (in)famous Xcontrol control panel. With that you can switch between 8 and 16 MHz and also decide if the cache should be enabled or not. However, the control panel isn't always possible to access. For all of you that hates the control panel or can't access it because you aren't running GEM I've written four SMALL programs that lets you configure and examine your MSTE. The programs has a PRG-extension so that they can be run from an AUTO-folder if wanted. They are NOT intended to be run from GEM (they use Cconws to output text). Speed-SWitch v1.1 does NOT check if your computer really IS an Atari Mega STE. It hasn't been tested on other computers, but it will most probably crash if run on a ST or STE. WARNING: DO NOT RUN THESE PROGRAMS ON AN ATARI TT COMPUTER. THEY CAN'T DAMAGE YOUR TT, BUT MAY VERY WELL CAUSE A FATAL CRASH WITH ONLY ONE WAY OUT - RESET. Technical note: --------------- These programs manipulate and read an address in high memory (a port). I don't know if there is an 'official' way of setting the speed on a Mega STE, but I'm sure that this will work on all Mega STEs, now AND in the future. The programs make no assumptions about memory that they don't 'own', so they should all be possible to 'Fast Load' (by setting the fast-load bit). Copyright and disclaimer note: ------------------------------ These programs and their source-codes are copyrighted. You may NOT distribute Speed-SWitcher for profit in ANY way. When/if distributing Speed-SWitcher ALL 9 files MUST be included. You are NOT allowed to alter the sources, recompile them and then distribute the programs without written permission from me. However, you can configure the programs to suit your own needs without my permission if you DON'T spread them. I take no responsibility for any damages that these programs may cause on you or your equipment. It's all your fault if anything goes wrong! The code is VERY simple, and I can't believe that there are any bugs in it. However, I can't guarantee it to be totally bug-free. Shareware note: --------------- These programs are SHAREWARE. You are allowed to try the programs. If you find them useful and want to continue to use the programs I ask you to contact me at any of the below mentioned addresses. You could also call it 'PostcardWare' but with the difference that you also can call me or send me electronic post. When you contact me please include your name, addresses (including electronic addresses), phone number(s) and a small note telling me what you think of the programs and the sources. Demo note: ---------- To all you demo-programmers out there I just want to say one thing: Begin making your demos work on Mega STE computers and other computers that run faster than 8 MHz. If you MUST use full overscan or sync/hardware-scrolling then check how fast the computer runs and exit if it is faster than normal. If you can't check how fast the computer runs you are no demo-programmer, just another LAMER! Many thanks to HiSoft for their excellent Devpac 2! Also thanks to John Townsend for inspiration to the WHATAMI-program! Greetings to everyone I know!
