Title: MC68010L10 cpu question

WOuld it run at 10mhz or at the stock 7mhz that A500/2000/etc runs at ?

7Mhz unless you change the clock crystal on the A500MB to 10Mhz.

It's a military spec 010. :-)

btw, I saw that beast of a accelerator you're ebaying! Very awesome!

"This chip will give your machine a boost in power and extra CPU instructions over the standard 68000 part."

Yah, it's true.. you do get a few extra instructions but hardly anything compared to a 020/030 CPU.

Yah, a mighty 5-10% boost in power.. like that's anything compared to a real turbo board.

I personaly wouldn't pay more than just a few $ for a 68010, I'd rather save the $ for a real accelrator that can give me a HD controller, Memory expansion and more.

Also certain instructions (MOVE SR?) are privileged on the 68010, so badly written code for the 68000 will break on your new CPU.

I got this chip from Motorolla back around 1990, and put it in my Amiga as a drop-in replacement.  The benchmarking programs I ran reported something like a 3% boost in 3 or 4 of the tests, and no change in all the others.

And as mentioned in the above post, it increases incompatibility by some factor.

I remember my Hurricaine '020 board also gave a tepid perfomrance gain - and that was a 14Mhz '020!  The reason was, the system lacked any RAM that took advantage of the better CPU.

If I recall, all accelerator boards for the Amiga get thier speed increase using either a combination of faster chip/faster RAM, or faster chip/cache RAM.

So does this chip need to run at 10MHz for the boost, or will running it at 7.14MHz provide the boost?

I think that the "boost" most likely cannot be detected with naked eye. :-)

I'm not competent to change the clock to 10Mhz (14 maybe...)

So yes, you get the "Boost" at 7.14.  :)

Mostly I'm surprised that I called up Motorola one day and said "yes, I'd like to evaluate a 68010 please" and they sent me one!!

My MC68010L10 runs at 7MHz too on Amiga B2000CR Rev6.
How to change the clock crystal? :angry:

Don't do that - the crystal controls the timings for the entire motherboard.  your best bet is to get a proper accelerator.  However if you want to try, there's hacks out there that allow you to run a CPU at 14MHz (1/2 the speed of the crystal).  Off-hand I think these mess up floppy timings and a few other things.

Here you go, here's a thread on it:  http://www.amiga.org/forums/showthread.php?t=28259

TL;DR.  Just get yourself a proper accelerator.  :hammer:

Thanks for the info, accelerator is expensive :(

I you have hard drive in your A500/A2000 and no turbo card, then 68010 offers some extra compatibility to WHDload games.

So if you just play whdload games and maybe something like deluxe paint, then 68010 gives to you some extra.

I have heard that that there are some apps wich require 68020 but works with 68010?? I don't know is it true.

Amiga is not a cheap hobby.

Simply replacing your 68000 with a 68010 chip (about $5 bucks on ebay), which it sounds like you've already done, gives you about a 2-5% speed increase (which is hardly noticeable) and gives you access to the 'Quit' key in WHDLoad.

Beyond that add some true fast RAM, if you haven't already.  That's usually good for a 20-30% speed increase over a stock system.

Putting one in the CPU socket 8mb ram boards yields a bit of performance. I've got several 10s just to see, all new ones.

Interesting, thanks =)

There is only one thing in the 010 that is faster than the 000: it has a six byte (!) loop cache which means that the smallest possible loop on a 68k, a short instruction followed by a dbcc instruction, will be faster than on a 000. Everything else is identical speedwise. That one instruction became a privileged instruction is hardly relevant, it has always been a privileged instruction in all 68k since the 010 and that was never much of a problem.

The mini-loop is very rare in normal code, it was intended for speeding up hardware polling and perhaps a mem-copy. In my opinion spending 5$ for an 010 is 5$ wasted.

Actually, there is a bit more. The multiplication on the 68010 is almost twice as fast, and the division is also ~20% faster. Not that this makes a major difference in many practical applications, but there is more than the loop mode that improved.
