I've got a Minimig with 4 meg and the arm controller in a loriano case (or however you spell it)
I'm now in the process of selling all my Amiga classic gear (sold my Amiga CD32 last weekend and have 2 x Amiga 1200's to sell) as the Minimig is replacing them all.
For the Amiga 1200 and CD32 AGA stuff I'm going to be using WINUAE.
Frontier on the Minimig runs just as fast as an Amiga 1200 with a 030 running at 50mhz, I know this as I have compared the two side by side!
You'll love the minimig... classic platform on modern hardware!
