I've had a couple of questions, here are some answers:
Q: How much did all this cost?
A: More than you'd like. Here's the cost breakdown:
I/O Board $30
SDRAM Board $30
Tynemouth USB Keyboard Adapter $65
Amiga 600 Case $35
Amiga 600 Keyboard $35
Zero4U USB Hub $15
Various bits and bobs: $50
Q: Does the MiSTer support an 030 or 040?
A: Not that I am aware of. I believe the max CPU type is currently an 020. However, the project operates as open source so anyone is free to contribute.
To the question of if the MiSTer supports 68030 or 68040...
It does a 68020/100mhz - it clocks faster than An A3000/30.
And it isn't like emulation - where it burns up on Sysinfo but real world applications choke on bottlenecks.
I have an A500 with Classic 520, another with the ACA 500 with the ACA 1220/30,
And an Amiga 600 also running a 68020/30.
What I've noticed is that things that are compatibility issues that happen on a real Amiga with a 68020 (for example, garbled audio in Bards Tale 1,) don't happen in WinUAE or UAE4ARM...
But the MiSTer FPGA is such an accurate recreation of the genuine architecture that if the real Amiga has issues, the MiSTer core has the exact same issues.
I discovered this because I played BT1 on a MiSTer... then I decided to switch to WinUAE (easier save states when later in the game, I didn't want to go back to the guild to save on very long levels...) The music was garbled on the MiSTer, but sounded fine on emulation of a 68020. So, I thought, "Well, MiSTer isn't THAT accurate!"
Then I got the accelerator, and loaded up BT1 there, and to my surprise, the audio glitches from the MiSTer were there on the genuine hardware.
And it is worth noting that I paid $400 for my recent A600 as a complete kit with a 68020, mmu, 16gb CF hard drive, and 15khz LCD. So this idea is actually pretty economical.
