Hello at all,
I made a new cryptocoin a couple of months ago, called Amigacoin, to support Amiga platform (do you remember old Commodore computers?).
It's already used by many Amiga users and soon a PowerPC version of wallet will be available, at the moment there are only executables for Linux and Windows.
Anyway, it's another Litecoin clone and has follow specifications:
_ 2 minute block targets
_ 2 billion total coins
_ 100 to 1000 random coins per block
_ 1440 blocks to retarget difficulty
... and also it's pre-mined (but its difficulty is very very low) and distributed among Amiga fans.
For more info, look here:

Thanks!

PS. Any help is welcomed (for example, it needs a more professional site and a build for Mac OS).  

Playing with "old" computers? I don't think, especially now there are a lot of pointless coins.
Amigacoins are used by many users and developers, indeed, they're few compared to good times of Commdore era, but Amiga is still alive.
Anyway, MacOS wallet is available, obviously you need Snow Leopard (at least) and 64-bit Intel CPU.

Hello,
which miner are you using?

Yep, just few Amiga users (with old PCs, of course) are mining it at the moment. I'm trying to get in touch some pools and markets for spreading, obviously more people use it more better is. 

The only time I had a go on an amiga it was to play super space invaders. That was years ago and it was ancient technology then. I never dreamed someone would use an amiga to mine on. The difficulty must be really low because I bet a modern smart phone has more computing power than an amiga.

Theoretically it's possible, latest AmigaOS (4.x) supports Radeon HD series 6xxx/7xxx, the huge job is port to Amiga platform many libraries like Boost and DB Berkerley (there is only a very old version - v4.3 - I'm using v5.1), OpenCL and (most important) the wallet. Unfortunately it's based on litte-endian standard while Amiga uses big-endian (it has a PowerPC CPU), like Apple Mac G5. Someone wrote a Bitcoin wallet for old Apple Mac in early ages, but I'm not very sure that can be useful for us.
   

Please explain how this is legitimate (I'm not accusing you of anything, just being curious):

It's already used by many Amiga users

-Where? How?

and also it's pre-mined

-Yes, I know. You were bragging a bit about it on amigaworld.net:

I pre-mined a lot of Amigacoins (many thousands blocks, every block has 100-1000 coins)


According to my rough estimate, you have premined some 400k blocks... that would be approximately 200M Amigacoins.

Sorry, I mined less 10k blocks (not 400k) and if you can see the wallet, you'll read around 22k blocks mined until now.
I'm giving those coins to many Amiga users for free (like Auroracoin) and usually I don't ask them how they'll use.
Absolutely no bragging.
If you own and work on Amiga, you're welcome, ask me for some coins.  

Whoops... I was being silly (and tired). Sorry for that, 22k it is.

Yes, good idea!
