A Minimig question and a ramble
« on: March 12, 2010, 11:28:20 AM »
I've only been casually following Minimig over the last few years since it was 1st released, it seemed cool, but not really for me. Recently though with the recent changes it has started to appeal to me a lot more. Having said this though, I've only been reading bits here and there so I dont think Im completely up on exactly what has happened. It now has AGA, plus a faster clocked 68000 cpu, and more RAM (both chip and fast) is my understanding, but Im not exactly clear on the specifics. I even read a few (vague) posts that mentioned '060 (although it wasnt clear in the few posts I read if this was theoretical, or based on something that has been mentioned). Could someone please clarify the details of the recent changes please ?


ramble mode on:

Also, on a related topic, does anyone know how many minimigs are out there in the wild? The oldschool guy in me loves the idea of making games that can take advantage of any enhancements minimig has over standard customchip based classics, lots of chipram to play with and faster cpu than stock a500/a600/a1200 (base platform for most games). I've always wanted to see what an enhanced amiga could do for areas that it excels (ie,2d and not doom clones). An inclined person could develop new games with minimig in mind, but also maybe enhanced classics too (with maybe a few slight variations depending on used hardware(a faster cpu/less or more chipram/etc).... point being if there was enough new "classic amiga hardware" ppl out there to warrant games that target a higher spec than what was mostly targetted before I'd be a happy man :-)  A pipe dream, probably, I'd love to see what the amiga can actually do in regards to games when given more ram and faster cpu to play with, something that unfortanately we never got to see because of doom, etc. (ie. by the time games were made that needed higher spec amigas they were mostly doom clones). Especially with the minimig (Im under the impression even though its ocs/ecs/aga certain bottlenecks have been removed?) I'd imagine there's the potential for Neo Geo quality games (in terms of qfx/sounds) and maybe beyond. Would also be quite novel to sell amiga games on something akin to a cartridge :-) (minimig/sd card (or whatever data medium it uses)). It's just a fantasy, but it sounds fun to me  :-)

Oh, also, despite sayind Id like to see non doom games for enhanced ocs/ecs/aga amigas has anyone run doom on minimig ? I'd be interested to hear how well it runs  :-)

Thanks for listening  :-)
Near as I can tell this is where I write something under the guise of being innocuous, but really its a pot shot at another persons/peoples choice of Amiga based systems. Unfortunately only I cant see how transparent and petty it makes me look.

Your post doesn't make it evident if you realize that the changes you mention don't quite match up to the capabilities of the current commercially available version 1.1 minimig board. It is ECS/OCS only. It has 2 MB of ram of which 512 kilobytes is taken up by the ROM (leaving you with 1.5 megabyte freely assignable between chip and fast). The 68000 CPU can be overclocked to 20 MHz (at least on my board) and there are some other overclocking options available.

It is possible for someone with a steady hand to solder on more RAM, giving you a maximum total of 4 megabytes.

With a future minimig board with a more powerful FPGA chip the aforementioned things like AGA seem to be possible.

I have two minimigs one with the ARM microcontroller (replacing the old PIC one). It runs really well with most software that would run on an a500/a600.

@polardark

Minimig sold today typically have 4MB of RAM installed already, also the "high speed" mode currently is 7*7.14MHz - ie close to 50MHz, however the RAM speed and various other factors become bottlenecks.

But anyways, what fishy wants to know about is not the commercial MiniMig 1.1, but the FPGA Arcade/Replay.
