*REAL* Amiga Mini, avoid crap

Hello all,

After seeing that thread that talks about another crappy emulation-based AMIGA (and even the scammers of Cloanto involved), I think I have found somethig WAY more interesting... What about an Amiga computer re-implemented in FPGA for 45$?
This board seems to run no other than the incredible Minimig core, for that price, and it's as mini as possible:

http://www.atari-forum.com/viewtopic.php?f=116&t=32280
https://www.indiegogo.com/projects/f...oard-arduino#/

Note I am not affiliate with the board or devs behind it: but I believe it's what an "Amiga Mini" should be, using the only possible technology to make justice for the original system.

EDIT: There's also an FPGA hardware implementation of an X86 computer with VGA and OPL3 for this board. So it's HARD to resist

I am mainly interested in the old skool PC Core. I have a MiST and ZX-Uno but only the ZX-Uno has a PC Core, but mine only has 512Kb of RAM so the PC Core is very limited.

Being able to play SWOS perfectly with a pocket travel device on HDMI is also very interesting

I thought I read somewhere the AMIGA Core could be 68020 ? MiST has 68020 so it would be good if a WHDload setup could be run on the Flea.

I think it best to almost follow a RPi Zero guide which puts it in a NES cart, so that the ports are protected by extension leads. MicroSD ports are not the best for lots of plugging/unplugging.

It looks like sound out is through HDMI? Nice if you had option to route out via gpio pins to 3.5mm jack. Handy for using with DVI monitors.

The project creator said it would be possible to output sound via gpio for a 3.5mm jack.
Great for existing DVI monitor and PC speaker setups.

I have asked some questions regarding if you can use a USB hub ( As AMIGA really needs 3 ports/devices) and to clarify if they are USB and PS\2 compatible or you need PS\2 devices.

@jediknight - what is the damage with UK postage? 52 dollars ?

If it's that PWM hthing like on Raspberry pis, it's absolute garbage. It's best to have a dedicated DAC. Hopefully one can attach it to the system.

You can do a lot better than PWM with an FPGA - both the Minimig and MIST use a resistor/capacitor filter fed from a GPIO pin for audio, and most cores use a sigma/delta modulator rather than PWM to drive it. While a true DAC is certainly better, the results are perfectly fine for 8-bit audio.

Project creator has said his Minmig port has up to 2mb chip and 8mb fast, so it should make a nice WHDLoad setup which will cover most AMIGA games out there.
There might be a possibility of AGA fitting in the FPGA.

With postage and credit card fees you are looking at about 41 for the UK. There are potential custom fees, but not that high. Hell, in year or so we might be paying customs on all EU goods!

Hello Everyone!

I'm the creator of the "FleaFPGA Ohm" board mentioned in this thread.

Just wanted to introduce myself and mention a few recent tweaks added to the Minimig ECS core ported to my board:

Very recently, I found robinsonb5's github repo and decided to try adding another 16MB expanded ram and also the CPU cache to what was ported previously. Here's the sysinfo result. Sysinfo also now reports an extra 16MB of 32-bit RAM as well.

Also tried WHDLoad (18.3) for the first time ever on my Minimig (had been using .ADF and .HDF files previously) and that seems to work for the dozen-or-so game demos I've had the time to try. I do plan on putting the tweaked HDL sources up on my github page soon.

Well that's all for now. If anyone has questions about my Ohm project, feel free to ask. Thanks!

Regards,
Valentin Angelovski
