I have the chance to purchase an Apollo 68040 accelerator for my a1200, seller mentions there are no drivers or Floppy Disks with it...can anyone tell me whether this accelerator board is recognised by the system without drivers? Is it compatible with every a1200 mobo revision or picky?
I'd rather not purchase if it is to cause me hassle.
Cheers

You should be fine with the standard 040 Library, but if not one of us can hook you up with the latest.
-
Drivers shouldnt be necessary for the 1240, but the apollo cards are picky about mobo rev.
The 040 also gets hot.
But if you can get it at a good price, then go for it.

I have 2 A1200's.
A Desktop Dynamites pack and also Amiga Technologies A1200
I dont know what mobo revision is in either one? I won't be busting the warranty seal on the AT one as it's never been opened.

No drivers specifically, but you will at least need the standard 68040.library. Not all of my OS disksets seemed to include this.
You should also consder RemApollo, as at least one of my older Apollo 68040 boards doesn't remap various resources from Chip RAM which can seriously hamper performance.

Awch booo, I don't have a Floppy Drive so dont know how I'd make these disks :(

Apollos are nice boards, but Amiga technologies A1200 wount't work without timing fixes
http://www.ianstedman.co.uk/Amiga/amiga_hacks/A1200_Mobo_fix/a1200_mobo_fix.html
I've also 2 A1200 computers, rev 1d4 and 2b, both works with timing fixed made. Without them only 1d4 worked and only with 3.0 roms.
You should open your amigas and check revisions, also you might want to add bigger harddrive.
040/060 accelerators works without drivers, problem is FPU wich doesn,t work without correct libraries.
Apollos has also faster (unstandard) chip ram access wich means that many games and demos works much faster with 040/060 apollos than any other accelerators. That is nice feature because A1200 is old and thats why quite underpowered computer, so every frame more per second is important.

I don't mind opening my Desktop Dynamites a1200 but do not wish to open the AT a1200 to keep it's untouched originality.
What revision mobo a1200 do the Desktop Dynamites generally have?
-
It should work with the Commodore library, but I suggest using the one from the MuLib package (AmiNet).
My Escom 1D4 board came new with the fixes already done, so you might get lucky. If the card works with your motherboard, they're fast and reliable, and some can be upgraded to '060.

The AT a1200 unit I have, has a sale date of 1997 suppose it's worth a dabble, if it doesn't work out for me, what can I get in resale value from Apollo 040 with 32mb ram?
-
Amikit has a repar service wich can do timing fixes? It shouldn't cost much.
-
Do you have a link please?

You may consider upgrading from the original power supply. they are weak and the 040 may tax it. Your mileage may vary. Most people use the A500 power supply which is better.

I almost forget that :) there are 3A and 4,5A PSU for A500, get 4,5A PSU and you wount have any problems

Why? There is no warranty to worry about. Without some fixes, this is one of the least compatible A1200 models you could buy.

I only really wish to expand my a1200 DD with accelerators.
Upon reading it could be a 1D4 mobo, but wont know for certain until I look.
I have a Amitek Hawk 4/8mb ram card I could put in my pristine AT a1200 model.
I do have the heavy type A500 PSU, it weighs a ton, literally lol...

OK that is what I bid and won, but to get to me in the UK it will be doing near 5000 mile journey over the Atlantic, I'm taking a big risk...
Aren't they worth considerably more? £250-300?
-
I've excatly same card, it is good that it games with working sim. It could be a problem to find working one.
It requires fan all the time, to keep it cool.
RemApollo is something that you should try out, it is like blizkick but for apollo boards
-
It varies what they bring in, the ones with the mach131 are worth more, since they can be upgraded to 060.
You might just be lucky :D
-
I had one of these back in the day (1996-1999), it really felt fast but the fan was noisy and it barely fitted into the trapdoor expansion bay (and with the large 3.5" drive I had also shoehorned into the case, as well as the quirky SCSI controller card, the case had a bit of a bulge in the middle.

That's a nice card you've won yourself there. The speed will blow your socks off! It already comes with a 32MB stick of ram, and you also have the spare simm socket on the top of the card for an additional 32MB (would need a tower conversion though as the keyboard gets in the way of that).
I have one of these myself and regarding the trapdoor all I do is slot the trapdoor cover on, but I don't clip it. Nor do I have a "levitating" Amiga as that would bug the hell out of me....I like the original level of the Amiga, so no extra height feet on mine.
The cpu will get hot though, very hot...just make sure that that custom rig is blowing plenty of air past the cpu surface. Also bear in mind that with the top Amiga cover removed, it will cool much better than when the cover is on.
As regarding ram compatibility, I can't say I've had any any problems with my Apollo, and infact it seems to be happy with any simm I throw at it, providing it doesn't physically conflict with the card.
Enjoy your card when it comes. :)

Paul what mobo revision do you have? :D

Paul what mobo revision do you have? :D
Rev. 1A for my Apollo1240. I've never tried it in any other revision though.
I have an Apollo1260 running on a 1D3 as well (same card, different CPU).
