It doesn't really use Amber. Minimig has it's own equivalent (also called Amber) but is unlikely to work exactly like the real Amber chip did.

In reality I dont think Yaqube's 60Hz mod really makes an NTSC minimig. It cannot because to do so you would have to  change the main MiniMig crystal (which is by default a PAL crystal). It's just a hack.

It is probably much worse. Yaqube's hacks, combined with MiniMig's original bugs combined with some of the traditional NTSC Amiga incompatibility :-(

Not true. There are no 3.3v 020 chips for example.

Thanks for the corrections, I'm not a tech. As far as the AGA Minimig, it wouldn't be built the same way, so it couldn't be called a MiniMIG. A system based around an FPGA with a software 020 or somekind of emulation using a faster CPU. The bottom line, from what I was told it's possible. Is it likely? well that's another story, certainly nor through any offical release.

The MiniMig costs almost nothing to make in volumes. All the R&D is done, you just find sources of the chips and a place in china to make em and churn em out. I don't think you realise what kind of markup there is on ready made MiniMig's. I think Acube probably made their money back (which is always a good thing).

While you could make an FPGA devkit with enough capacity for AGA + 020 (although no-one knows how much that would be for sure) for about the same price as todays retail MiniMig, you'd have to mark it up considerably to make viable profit.

I used to be disgusted with the markup on the MiniMig's, but once you actually look into all the costs which go with officially retailing an electronics product within Europe then you gain a lot of respect. It's not like they could just make them, flog em and split the profits down the pub. There is quite a bit of expensive red tape once you go legit.

You're right, it doesn't.  I've used it and I've run PAL software with no "clipping" of the screen like a real NTSC Amiga does.

No be perfectly honest, I tested a hell of a lot of software with Dennis' 50Hz core and then with Yaqube's 60Hz core and found no games that would work on one but not the other.

Unfortunately I only received my updated PIC from Amikit a few days before I had to return to work in Brazil and I haven't had a chance to test Dennis' latest core to see if any of the failed games will work.

I'm also looking forward to Yaqube's new core with ADF write support for more testing.

AlexH I was looking to produce a run of Minimgs the instant the BOM was released I got quotes of $85 first cost per board with a power supply, White box and A5 double sided instruction sheet in quantities of 100 units.
Rohs was like $10 more if I remember correctly.

The markups are justifiable...

Do you mean that to produce a Minimig is $100?

I now know first hand what it means developing and producing a new product for a market like the Amiga's.

It depends how many they made and where. Probably a little less.

The design of the MiniMig 1.1 and the chips it uses unfortunately makes the design overly expensive.

With a small re-work the BOM would come down even more.

Thank you everybody for your answers.

I see two different Minimig software compatibility lists :

http://www.loriano.pwp.blueyonder.co.uk/what_works.htm

Wouldn't it be a good idea to merge them ?

Easy, get a Classic computer for our little pieces of art,
and get a new board that means improvement to use new
software and new capabilities.


As I said, reliability is the key for me, so that a Minimig suits me better than anything else I know as long as the software works on it.

Quote
But as you can know UAE does fairly good on PC's, just
figure what could be emulated if you add some custom
oldskool chips on a new Amiga computer. (Emulation would
be way easier, way efficient for only a bunch of $ more)
That's what i mean.

Actual Amiga manufacturers that are able to design a
"minimig" that is not an "improvement" by itself but
an old computer in a new shape, could add the
imprescindible hardware used on that minimig to our
new mainboards to add some "oldskool emulation mode",
with a really effective result.
But noone decided to do that.


Yes, and adding real custom chips to emulation could solve my animation problem that I mentioned in my previous post.

Quote
As a resume, i would not buy a minimig, i would buy an
Efika or a Sam440ep instead a minimig, and keep at the same
time my old A1200 till the moment some of these platforms
reach the point of having an efficient backards emulation
using software or maybe using some part of hardware
either in future models.


I still haven't found the time to learn what the Efika and Sam440ep are.

Quote
the result of every improvement effort Phase5 or other
great companies also was "New oudtated hardware".

Why? Our Viper accelerators could not compete with
PC's in performance due the loooooooooooow clock rate
of our A1200 and A4000 mainboards... 14mhz. And if
you were able and lucky enough and rich enough to
afford an A4000 with some 3D card like the
"awesome" "Cybervision 64 3D" you got a really
expensive sollution using an S3 Virge chip, while
PC's were using GPU's even ten times faster...
Even my Playstation was more efficient than that
and costed a fraction of what my Amiga costed.


Of course, but you are talking about the 90s : at that time the harm was already done by the press, which on the contrary and most of the time _wanted_ the Amiga hardware to be old and slow and the software to be programmed for those setups (just open any video game magazine of that time), and the technology factor you describe cannot be considered as the primary factor of the Amiga's destiny - it's just a normal consequence of public perception.  And the high prices were just a normal consequence of this low demand.

Quote
That's what happens when new hardware gets stuck
by using a platform designed with standards
from 15 years ago, Commodore got stuck with
that retrocompatibility, so third party manufacturers
were not able to improve the system by themselves.


Retrocompatibility was important, and wasn't a problem at all in the IBM-PC world, so I don't think it is a significant factor either.  Since general public press refused to know the existence of the Amiga 2000 then 3000 and 4000, because of complex psychological factors, the public has ignored them as well, and the Amiga was already condemned to commercial then development death at the time the 500 and 2000 were released.  Since graphic or processor cards were equally ignored by the press hence the public anyway, I suppose that Commodore concluded that improving the system and joining forces with third-party manufacturers would not help the sales.

As I remember it most A500 owners (myself included) were unwilling to upgrade because:

1. The majority of games were poorly coded and would only run on bog standard A500/A1000/A2000.


I agree, and I think I can demonstrate that it is the only consequence of bad journalism.

Quote
2. High end/expanded Amiga's still had very poor printer output compared to the PC.


To my knowledge the Mac had similar problems, but survived.

Quote
3. High end Amiga's cost an arm and a leg - but still lagged behind the PC in most (all?) business applications.

4.Expansions and peripherals also cost an arm and a leg. Since only ray tracing software and the like could take real advantage of the added harware it seemed like a lot of wasted money to the average user.


That is only a secondary factor, since price is the consequence of poor sales, which in turn are a consequence of public and press perception.  In the 80s, 386 PCs had a worse quality-price ratio than a 68030 A2000, if I remember well.

Quote
5. PC's were becoming much cheaper, powerful and better supported.


This is a corollary.

Thank you for your help !

No


Well, the idea of buying a Minimig is not very exctiting anymore then, as I need it to run at least some games perfectly.  I think I will rely on others' experience.

STOLEN SOFTWARE


Who has edited ?  If this "stolen" means "copied although copyrighted", it must be noted that discontinued software on perishable magnetic media has to be copied in order to be used, and in order to be preserved if it has cultural/artistic value.  Any copyright is wrong preventing this, unless the authors/artists themselves expressly want their work to disappear (even this may be discussed when it comes to a masterpiece).



@TheDaddy

Thank you for your advices.  If I buy a Minimig I won't miss your case.

An ongoing issue with Amiga, since its inception back in the 80s was an unclear upgrade path. On top of that upgrade options (expansion cards in particular) were very pricey and seemingly aimed at some "professional market" (whatever that was back in the day.

At the same time, PC platform was becoming less expensive and migration path was very clear: you got yourself an IBM AT, you added some memory, Windows 3.1, some well-supported software and you could use it for pretty much anything you wanted without sinking a lot of money into each individual upgrade option. You could easily figure out what type of RAM your motherboard needed. You could easily add a hard drive to a PC. For A500, you had to spend $1500 for that GVP paperweight with a hard drive inside. In those days, you could get a very nice IBM AT for $1500 *with a hard drive*. I do not remember the price for Amiga's XT/AT emulator cards, but I remember that they were not worth the money at the time. This is why I ended up with an IBM AT and Amiga collecting dust. A3000 and A4000 were, IMHO, vastly overpriced when they were released. Consider that Commodore was never considered to be an avantgarde (as Apple for example) and this is again a marketing/perception issue.

Even today, as I am piecing together my Amiga collection, my head is "spinning" sometimes from all the upgrade options, their specs, differences and, above all, prices. PPC cards in particular were a disaster - in marketing, pricing and distribution.

Anyone blaming the Amiga users for Amiga's demise on the market is barking up a wrong tree. As with many other machines and technologies, wide acceptance, pricing and clear upgrade path can spell success or a disaster within a few years.

Amiga's current situation (lawsuit, no hardware) is just a continuation of the "market strategy" started back in the 80s: we are the best and you cannot do anything to us. As it played out, Amiga has slipped away because of that attitude and a much more inferior platform prospered (PC) because it was affordable, versatile and had much better software support (this also falls into "versatility" category).

PC platform also had an advantage of a broad hardware support from many vendors (not just IBM). This was very important for a teenager (or a home user in general) with a limited budget. Back in those days, IBM AT was priced 2-3 times the price of an equally well-equipped clone.

High-end Amigas were just as expensive as Macs and targeted a very limited niche at the time (video professionals and gamers).

There are many lessons in Amiga's demise and none of them seems to have been learned by Powers to Be who own the Amiga, in name, trademark or copyright.

Minimig seems to be a viable option, but it is still unclear to me what would I do with the board if I ordered it. It does not seem to be a complete machine. Maybe it is, but does not look like a complete machine.

On the hardware side, was upgrading an A2000 more unclear a path than upgrading a PC ?  To my knowledge, anybody able to upgrade a PC by himself was able to upgrade an A2000, and the others just untrusted the upgrade to their computer dealer.  On the software side, as A.org member Bloodline said in another thread, the drivers were sometimes weak or buggy.  But any hardware manufacturer knows that hardware is useless without an efficient driver : only poor sales can explain such a weakness.  So to my knowledge the "upgrade path" cannot be a first cause of the Amiga's demise.  

Quote

Price too cannot be considered independently of sales volume.  Anyway a 68030 A2000 had not a worse quality-price ratio than a 386 PC if I remember well, and at the same time the PC was aimed at "professional markets" even more than the Amiga.

To my knowledge, adding a hard drive to an A500 was easier than adding a hard drive to a portable/laptop PC of the same time.  A desktop PC of the 80s should be compared to an A2000, not an A500.

Quote

I agree with you, but the later the period the more important the sales factor.

Quote

Really ?

Quote

This is the problem.  As far as Commodore is concerned marketing was public perception.  And public perception was journalism.  Journalism should have been information : instead it was public perception, thus creating a spiral of commonplace.  Since commonplace was and still is "bigger is better" as well as "smaller must be eliminated", any computer manufacturer that dares to offer small computers with built-in keyboard but no screen is only a "console" manufacturer, in other words is not interesting and must be eliminated.  Every generic computer magazine I have read is a clear illustration of this process.  Apple survived mainly (only ?) because they had no such keyboard-computers along with their desktop computers.

Wasn't the infinite IBM-compatible PC hardware a source of head-spinning ?

Quote

PPC was the end of the Amiga, so its "marketing, pricing and distribution" cannot be anything of an early factor : it was a foreseeable consequence.

Quote
Anyone blaming the Amiga users for Amiga's demise on the market is barking up a wrong tree.


As far as technology is concerned, most people buy what they want or are told to buy, so even the best product may not survive if image and word of mouth are the only rule : information is the key of objectivity, so journalists were the key of the Amiga's destiny.

Quote

In the 80s there was hardware, and general public doesn't care about what is behind the product.

Amiga has slipped away because of that attitude and a much more inferior platform prospered (PC) because it was affordable, versatile and had much better software support (this also falls into "versatility" category).


In conclusion, again I think that these factors are mainly consequences of a primary factor.

I don't know anything about what are and do those "Powers to Be who own the Amiga" nowadays, so I can't express any view about it.
