getting a 16mhz 68000 and doing the 14mhz hack will get you more performance.

i always wanted to get the 25mhz 68000 and try 28mhz with the agnes? clock

Yeah !!! That 16 mhz and especially the 25 mhz 68000 performances must be really impressive for and Amiga 500
trying to reach the great levels of the 80/90s Arcade machines ! :crazy:

I think, my first A500 has still got its '010 inside - in my memory it was like 0-3% faster, in synthetic benchmarks you could read 20%.

I gained quite a bit more by replacing the system clock with a 32 MHz crystal :lol: - my very first overclocking job, 11% faster. My Profex/Philips monitor whined quite a bit about the increased horizontal frequency - but even the blitter was faster. No that I think about it: it probably was the fastest Amiga blitter ever (outside C=).  :-D

The 68010 is a little more useful these days, not because of speed, but because of its VBR, which many WHDLoad installs take advantage of.

@[Everyone stating a clock crystal hack is better]

Any good How-To's/FAQ's/diagrams that provide good info on doing this and overcoming things such as not being able to use your floppy drive, etc?  I'm interested in this... Now that I've acquired a nice A1000, I may experiment with my A500 a bit... See what kind of performance I can squeeze out of this bloated-keyboard-with-a-floppy beast.

At $12.65 including shipping, the 68010 is next to free.  Considering that accelerator upgrades for the A500/A1000 go on eBay for the hundreds (US $), a pesimistic average of 3% gains in speed by a $12 CPU isn't really *that* bad.

Does anyone know how it behaves with DPIV?

Yes, exactly! I was wondering why I kept it in the A500 - that's it. With fast RAM and heavily loaded chip RAM that does make a difference!

[yock1960]

Boy! I started quite a discussion. Anyone interested in the other two chips once I get them? :-)

Seriously though, I just want my A500 to be all it can be...without breaking the bank.....which I kind of already did with the fast memory I bought.

I just enjoy tinkering and tweaking.

I'd love to figure out a way to get my old Mac Plus accelerator (Micromac Performer 16mhz '030) on this thing....but I'm I'm not quite ready to blow it and the Amiga up!

And some old emulation software - but system-friendly stuff can be fixed via "degrader" applications such as TUDE.

I always used Decigel in startup. Must have been on one of the first Fred Fish disks. I think it was even reset resident.

Upgrading an AMIGA A1000 with a Motorola MC68010L8 - 29-Mar-86

[InTheSand]

Ah, had never heard of that!

I only progressed beyond a stock 68000 when I got my A1200 in 1994, and by then was using TUDE for most things degrader-related.

It's here on Aminet, so I might grab it later and take a look!

Ah thanks, it says "update to the version on disk 18" there. Never used the update though.

MC68010 & 2MB FastMem @ 14,28 MHz



SysInfo Version 3.24

SysInfo 2,89 vs. A600 n. FastMem
SysInfo 2,20 vs. A2000 w. FastMem
SysInfo 1,xx vs. A1200 n. FastMem
(cant remember exactly, but its faster and A2500 ~ 0,8x)

It runs perfectly on my A1000!
With DeciGel patch (modified Kickstartdisk) everthing works 100%.

@piru:
... with a modified exec you´ll never get any problems with a 010!
I thought, that YOU know all about ....  :-D

DeciGel is actually only required for _very_ few programs. Basically mainly programs only written with the 68000 in mind and not compatible with any other following 680x0 CPU.
Ah memories, I had a Blizzard Turbo Memory Board myself back in the Nineties. It was always very obvious that there was only little speed advantage when disactivating the Fast-Ram. Note that there were even 14Mhz accelerators without any fast Ram at that time and some people were really expecting to double the speed only by swapping CPU and crystal.

Already tried Interceptor or Knights of the Sky? Nice speed-up there.

[Piru]

.. with a modified exec you´ll never get any problems with a 010!

Nonsense. You get troubles with 68010 with certain games. These games use supervisor mode directly, assuming 68000, and die horribly. There is absolutely nothing exec can do about it.

exec handles 68000-68030 without any patching, anyway.

68010 offers VBR, it makes possible to use WHDLOad quit key

[derringer3]

In the '90 i never heard about whdload, and i have tons of games, mostly in floppies, some which can be installed in hdd. I have never problem with 68010. If i have then is about the 3.0 kickstart. But when i switched back to 1.3 these problems are gone.
