Amiga 600 2mb chip hard hack

[supremo]

Dear all:

I have just purchased an A600 with a 2mb chip hard hack. I know there are two types of hacks, one prevents the expansion port to be used and the other not.

There is an easy way to know which kind of hack it is?

At the moment, I don't have any card to test the expansion port. (I want to purchase an ACA630).

Another information that can be useful, is that it has a 68010 chip.

Any help will be very appreciated.
Thanks and regards.

Never seen or heard of this being done (successfully) before. Very interesting.
The ACA630 clips over the 68K chip, so it wouldn't be affected by the status of the trapdoor connector. Whether the 010 throws it off is another matter - my guess would be that it doesn't, since the 010 is pin compatible.

You'd probably seen to ask Jens Schoenfeld directly whether the clockport and other goodies on an A604 would work in such a machine.

Got any photos of the board? I'd love to see what it looks like.

Thank you for the answer. I didn't know that the ACA630 is a "clip over" expansion.

I will post pictures asap.

Regards.

Definitely, that is NOT good news for me, because I did not received yet the miggy. The seller said it is working fine, but...

Anyone ever seen a working hack?

I know that, even if it works, it can be a very unstable machine.

Ok, let's see what happens.

Again, thanks.
Regards.

That's a very good question.

supremo, both of the mods you described are easily done on a 500.

I am totally sure.

But the 2mb hack seems pretty common. This is one of the references: http://www.amibay.com/showthread.php?t=8500

Update:

I have received the 600. Although I have not tested it thorougly, it works perfectly, and detects correctly the 2mb chip ram. It has a 010 too.

Pictures soon.

Ok, attached are 3 pictures. I can take more on demand.

Cammy, I have just purchased an CF IDE adaptor and a 8GB CF card. I am planning to get an ACA630, but I have decided to wait for the 40mhz version. Regarding the 3.1 ROM, I am still not sure to buy one, which is the main true advantage? I am interested in one of those S-VIDEO adaptors. The only place to buy them is on that web page?

Thank you all for the comments.

Regards.

Just curious, but can you get some sysinfo specs on the HW setup?

I am curious too

My problem is the following:
The only diskettes I have now are: workbench 2.05, extras and fonts. I cannot even install the SO in the hard disk. I purchased this:

http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=220720794483&ssPageName=STRK:MEWNX:IT#ht_2472wt_952

but came with no install disk. Now I am asking the seller if he can sell me an install disk, but no answer. By the way, maybe someone here have one to sell/gift? My location is Germany, until 31st july.

I think the best option is to get an CF transfer kit.

Thanks.

ACA630 exists only in 25MHz with 32MB RAM. There were some few models that had 30MHz and 64MB RAM.
No 40MHz version is announced for future from Individual Computers AFAIK.

If you want to run WB3.1 then you should upgrade to Kickstart 3.1. Even if you wanna use the HD you should check that your Kickstarts ROMS are >= 37.300 or else you won't be able to boot.
Best Kickstart for A600 pre 3.1 (40.63) is 37.350.

Yes, probably you are right. I am based on

I am very sorry to say that the computer is very unstable. Very often, when I insert a diskette, the computer resets, and a green screen appears.

It is well known that the green screen indicates error was found in Chip ram.

I think the problem is that "second level" memory chip is too close to the disk drive and the slightest movement resets the computer.

Any advice?
Thanks. regards.

Ok, I added additional screws and the problem seems to be solved.
