Here's a thought... How using the original design, with headers instead of the ports... Then having different boards to mount it to via screws and ribbons. The different boards would then have ATX and ITX layouts or whatever else. The mainboard would be the same, it's the board it's attached to that varies.

A4000D, A3640 OC-36.3MHz, custom tower, Mediator A4000D. Diamond Banshee 16M, Indivision AGA 4000, GVP HC+8.

Mac Mini 1.5GHz, that might run MorphOS someday, when the fools who own it come to the realization that 30 minutes just isn\'t enough time to play with it enough to decide whether or not you like it enough to cough up $200.

Baby steps folks. Nevermind the PCI and IDE and all that crap. If future expansion is in our minds, we should focus on Zorro-II and possible RAM/CPU expansions first. Zorro-II being the first priority, as there are many A2K expansions out there (like SCSI interfaces) that would be well within the realm of MiniMigs current specs.

Ok, let's get off the USB track of thinking here folks. For all intents and purposes MiniMig is an A500 clone. USB will not work worth a flip in this current code / CPU state, nor in the near future.

Yes, the eventual possibilities are endless, but until one of you geniuses out there figures out how to code the complete AGA chipset, FORGET USB! Besides, the only USB stack I know of for Amigas is a little hard to license right now.

From a development standpoint, it'd be far easier for expansion purposes to focus on creating an A2000 clone in ATX form. I personally think that's the direction we should be heading. Zorro II expansion, with a push towards ECS chipset compatibility, fitting in a nice ATX (not ITX) case.

Once we have Zorro II slots, there are numerous ways of applying ATAPI interfaces to the system already available from your friendly Amiga retailer.

Hang PCI for a while too. Let's simply focus on making this thing compatible with and comparable to the real thing before we go fumbling around with things that far outside of the scope of the project.

Dennis gave us A500 level, next step is A2000 level.

Meanwhile, with regard to the CURRENT design, I think the board could (and should) easily be formed to fit the ITX formfactors, just to give it something better than two sheets of Lexan for a case... And to appease all of the ITX fanatics that seem to be littering this site.

Personally, I love my big burly manly computer cases that take hand trucks to move around. But that's just me. I'd cram the thing into an old SGI Origin 2000 server if I could!  :lol:

Oh, add me to the list of the interested. Form factor doesn't matter. Original would suffice. I'm hoping by the time they're ready I'll be out of my financial woes.
