Minimig (A500) Motherboard PCB rev 1.0

Paul · 12 June 2006, 19:51

"Amiga guru hardware Dennis van Weeren revealed the PCB of Minimig. Minimig it is an A500 designed to fit on a 2 layer motherboard sized 120x120 millimeters equipped with FPGA circut which emulates Amiga chipset. It has no IDE controller, but MMC memory card slot that should be enough for all purposes on any A500, and it emulates perfectly a very large quiet-hard disk. Next step is to testing if FPGA fits and works on a real manufactured Minimig motherboard (actually Minimig lays on three separate little boards connected by cables).

Dennis stated various times that he want to leave the project open to those people who want to realize it by themselves, and that there will be no AGA version as he made all this job for pure fun.

That is indeed GREAT AND EXCELLENT news! way to go! I wish someone puts it on a pci card and we can use it on our pc's or whatever platform!

though I must say I am a bit dissapointed that Dennis shows no interest in ECS/AGA or releasing the mmc->floppy drive as a standalone product... but it's good that he will release the plans, someone could expand and make better minimigs (030/060/aga/pci/etc!)

DENNIS U ROCK!

It's called boredom, after you get a project like this working you soon loose interest.

Dennis said that he wanted to retain control of his work... I can only speculate, but I think this means it is going to remain closed source but you will be able to download the JDEC files for the FPGA.

DENNIS U ROCK!

I do not think the documentation exists, to recreate the ECS/AGA in an FPGA.

Unless you have a way to copy the transistors from a chip (all the chips that make up the AGA) into a gerb file.

I think people worry unnecessarily about AGA compat. I mean over 90% of games are OCS aren't they? And Minimig will be about games as it will be 68000 only.

IF MiniMig was a fast 030 or 040 emulation then maybe it would be worth worrying about AGA.

Yeah, I'd be happy with any mini Amiga system, no matter what it was

A600?

Methanoid · 16 June 2006, 16:03

Minimig will be 15cm square mobo.. thats small compared to an A600 even isnt it?

But MiniMig is something special. I'd REALLY love an ACCESS Amiga clone, but I missed out on the last one I saw on eBay

You should be aware that Mini-Mig is an Amiga chipset interpretation.

It will contain bugs. Compatibility will be high, of a similar level to WinUAE (one of the sources of information upon which Mini-Mig was based.) but it will not be 100%

A Mac Mini running WinUAE is small

Probably smaller form factor than 15cm x 15cm and it has other uses other than WinUAE.

How much did it get? I might have one...

musashi5150 · 19 June 2006, 09:51

An "untested" Access with floppy drive kit (no drive) went for just over £100. I decided that it wasn't worth the gamble for 'untested' hardware...

Anyone got a pic, I have never heard of this 'Access' clone of amiga... i feel like a newbie

Thats.... Just..... AWSOME!!!!!!

I WANT ONE!!!!! hmmmm maybe two!!!!!

[edit]

interesting how they solved the timming issues between the co-processors, and thus achieve 2.8 times faster than a stock A12... i thought it was just an inclusion of fast mem, but this is not so.

Interesting how it uses an original chipset. I imagine that that's one of the many good reasons there's so few of them out there.
