Apollo 1240 @ 25Mhz. It is untested, my risk. Am waiting for it to arrive.

If you look at the pics, is that what looks like residue anything to worry about?

Is it easy to add an extras simm slot and overclock to 40 or 50 Mhz without damaging it?

Will i see a huge improvement over my current M-tec 1230 @ 40Mhz with 8Mb ?

I will be installing this in my A1200 desktop.

Great that it is more than twice as fast besides that this is PCMCIA friendly and goes up to 32MB unmodified as opposed to my 030 Mtec with 8MB and PCMCIA unfriendly.

Now i hope this card works.

So is the second simm easy to install? My soldering skills are far from perfect.

I am using an A500 standard PSU with my A1200. Is that sufficient for the Apollo or will i have to use some sort of ATX PSU modded for the Amiga?

Well done, I hope it's all working fine for you. Can't tell what the residue is on yours, but my Blizzard 1260 has had a small amount of residue around the CPU pins since new (about 10 years) with no problems. Most probably leftover flux from the manufacturing process. Anyway, the differences are that the 68040 isn't actually 100% compatible with the 68030, as some functions have changed or have been removed - especially in the FPU. To compensate for this, there's a 68040.library which you need to have installed if you don't already have it, so most software will work fine once this is in place. It's just something to be aware of really, in case you find some software which crashes but worked before on the 68030.

As for overclocking: I wouldn't do it. The 68040 is already a pretty hot chip (the hottest of the 68k range) so clocking it any higher is only asking for trouble...

Thanks. Guess I won't be overclocking it then. My Amiga is mainly used for whdload but I do like the os to be nice and sleek and as good looking as possible and I also want to use os3.9 and unfortunately that is a bit of a challenge with the m-tec as it is PCMCIA unfriendly above 4mb.

I don't think it is safe to clock a 25mhz 040 up past 28 or so in a desktop case because of heat.

You may want to see if that card could be upgraded to 060 if you really want speed. I do know that the 060 operates on a lower voltage and generates around the same amount of heat as an 030.

Yes I thought about the 060 thing. But definitely not for now as I'm out of funds.

The card arrived today. Shoved it in the Amiga, switch on and it booted perfectly first time. It has 16Mb fast ram and it is REALLY FAST!! Love it

So far all my WhdLoad games work perfectly.  Me very very happy.

One thing, i noticed that the trap door cover does not seem to fit anymore. Is that normal?

Also, should i be worried about the battery ever leaking and ruining the board?

Ah i see what you mean about some games not working... I'll open another thread for that. But most work fine at least.
