4731.0. "Is 'New14accel.lzh' worth it ?" by VIVIAN::D_VISTUER () Thu May 09 1991 21:05

    I have come to the conclusion that I have a need for more speed.
    Therfore, I originally intended to buy an SSL or CSA accel' card.
    However, I am no longer in a position to do this.
    
    I have discovered the 2 cheap accel' projects and have evaluated both.
    It seems that if I was to built one, there is really only one choice.
    The 'new14accel.lzh' project is it !.
    
    Hhmm..!, seems easy enough. But I have several burning questions before
    I embark on my quest...
    
    1. Has anyone tried it ?.
    
    2. Does it work ?.
    
    3. Any benchtest comparisons available aside from those supplied ?.
    
    4. Is it reliable/compatible with the rest of AMY ?.
    
    5. To squeeze a little more performance out of it, can a 16Mhz 68010
       be fitted (If such a beast exist) ?.
    
    6. Any problems with software ?.
    
    No doubt there are other questions, but I'm sure,they can wait !.
    Dependant on feedback, I will decide if it's worth my best shot.
    Finally, what was the problem with the 'Cheapacc.lzh' project ?.
    
    Thanks for any info.

4731.1	history repeating itself	SALEM::LEIMBERGER		`Fri May 10 1991 06:44`	16
	You posted on this on note 4585 awhile back. I had managed somehow to go off on a tangent with the CMI product. My experiance with the CMI has been good, but I don't think I would bother with the project if the results I get fom the PA is all it buys you. I don't expect that the hardware hack will give you any more performance than I am seeing today. Back a long,long time ago many people tried the 68010 chip in their amigas. There is a note on this topic also. I think the end result was that most went back to the 68000. The performance gain was not worth the aggravation that they had with software incompatabilities. I know of a person that put a 68010 in his amiga 1000 just recently,and found some games that won't run. I don't like the thought of a hack that will not allow you to run in the normal mode when needed. Their was a saying we used when I raced GO Karts as a kid. "SPEED COST MONEY" It seems to apply to computers as well. bill
4731.2		MQOFS::LEDOUX	E.T. Notes Home	`Fri May 10 1991 09:22`	13
	re: base note... I haven't had time to try the "new acc" yet, although I bought the chips and hardware required. I am planning to do so soon. And to answer one of your last question, the "original" accelerator (from Australia) would not work A2000 nor A1000. I don't know of any one that tried on A500. The problem is that the screen would go to blue or green or sometimes grey and stay there. The problem was I believe, that some chips could not stand the added speed (memory?, agnus?...) Vince.
4731.3	Pinouts: Are they the Same ?.	VIVIAN::D_VISTUER		`Fri May 10 1991 18:10`	11
	Thanks for the info. Concerning this project, it appears that the 68000p8 and the 68000p16 have different pinouts. Is this the case ?, or is it pin for pin compatable ?. I think it is ?. Regards. Dave V.
4731.4	incompetent programmers	TLE::RMEYERS	Randy Meyers	`Fri May 10 1991 18:37`	13
	Re: .1 >I know of a person that put a 68010 in his amiga 1000 just recently, and >found some games that won't run. I don't like the thought of a hack that >will not allow you to run in the normal mode when needed. Actually the hack isn't putting the 68010 in the Amiga but the game itself. Any piece of Amiga software that doesn't work with a 68010 (or 68020 or 68030 or 68040) is broken and fails to conform to the Amiga development rules that were published six years ago. It's sad the the game programmers are so poor at their craft that they causes people to avoid speeding up their machine.
4731.5	it depens...	MQOFS::LEDOUX	E.T. Notes Home	`Mon May 13 1991 09:21`	7
	re:.3 The 68000p8 and the 68000p16 have exactly the same pinout if they are in the same packaging, ie: the 68000 comes in dip and square (� la 68030) package. Vince.
4731.6	Federation of Non-Guru's	GIDDAY::MORAN	I'm not bad-I'm just drawn that way!	`Mon May 13 1991 19:51`	15
	re.4 I'm not starting a flame but I totally agree with .4 Any programmer who writes code should make sure that it is written for 68000 and he should not use timing loops so that the code will work on accelerated machines. If you want the code to run faster on a 68020,030 etc then release two version of your program, normal and turbo just like they do with Ray Tracing programs. Programmers have seem to learnt their lesson on the IBM so lets not give the amiga a bad name with respect to code that guru's etc etc. Shaun.
4731.7	So!, 'Net' wiring list is wrong ?.	VIVIAN::D_VISTUER		`Tue May 14 1991 13:22`	18
	Re .5 Thanks. I will be using a 68000p16 that has the same style packaging as the current 68000p8. So therefore I can take it that the 'net' wiring list is COMPLETLEY WRONG !!!. Anyway, I have brought the components, so I shall be giving it a go soon and will post my findings. Again, any info/advice regarding this project would be gratefully recieved. Thanks. Dave V.
