Where are all the Minimigs?

[freqmax]

Weather the minimig1 hardware is possible to challenge without software, I dault it.
The configuration (*.bit) files might be another story. But forcing that of the net.. Not likely to succeed. There's a lot of other software where the infrigment is clear. And it's still online.

Hey you've met me ;-)

I am wrong all the time and openly admit it, like all good  engineers. You learn from your mistakes and you go on. Makes you a better engineer.

they dont copy things 100%, register for register, bit for bit.

Nor did Dennis. Did you even read the minimig thread?

I think he did or it wouldnt be compatible? The underlying bus structure is different (he said he merged chip&slow) because of his CPU-RAM interface. It's these differences I talked about earlier in this thread.

They[AMD] sell (effectively) 100% software compatible chips

Ah, yes but to get compatible (and they are still not 100% compatible) they license technology from one another SSE, MMX etc..

Twenty five years in commercial electronics and IT.

As an engineer? Blackpool eh... not much there in terms of ASIC stuff... (I know I grew up around there) Hmmm, BAE systems?

Another question, where is the best place to get MMC cards that work the best with Minimeg?

@henry case

why u want to build it your own if u can buy them for cheap on ripoffbay?

I didn't realise you could buy PIC programmers so cheaply off eBay, thanks for the tip Amazing. If anyone living in the UK is looking for a cheap PIC programmer (that will work with the Minimig PIC chip I believe), check this out: http://tinyurl.com/yru47g

According to the Digi-Key catalog the LF version operates with a VCC range of 2.0 ~ 5.5V and the F version with a range of 4.2 ~ 5.5V :-)

CD32Freak, thanks for the info. So I'm guessing L = Low Voltage.

By the way, the RoHS Replacement of PIC18LF252-I/SP is the PIC18LF2520-I/SP and the RoHS Replacement of PIC18F252-I/SP is the PIC18F2520-I/SP ;-)

I got the part name off the American Digikey price list I found on this forum. Am I right in thinking the US doesn't have to follow RoHS guidelines (I thought it was a EU directive)?

I very busy and too lazy to find the right power supply for Minimeg in the USA. Someone want to do it for me and I will pay them a little extra for their trouble?

@Pyromania

Do you keep referring to the MiniMig as MiniMeg out of some kind of protest, or did you just read it wrong the first time, and never noticed that it is MiniMig?

You need a REGULATED 5 volts DC PSU (I Have a 1 Amps PSU).
100Ma is to light, the minimig withe a optical mouse draws aprox 100Ma.

But then WinUAE would be illegal too. And so would be AROS and MorphOS. AROS is Amiga Rom Kernel Reference Manual translated to C ;-)

Heh, yeah maybe ;-) But if you were the company considering manufacturing them would you take the word of anyone who wasnt a qualified techie lawyer? Me neither.

I would not take the word of anyone, especially not from the Internet, saying that manufacturing them would be illegal.

I rather would check it from online resource, i.e. www.finlex.fi in my case. If I suspected there could be some problems I would check if such case has been in the court already.

You dont have to be a lawyer to understand it. Understanding legal terms will help, though.

Like I said before, if no-one at Amiga Inc. cared about the classic then there would be no problem. However they have a track record of trying to milk their ownership of Amiga for everything they can.

I know they milked Amiga users with their Amiga DE scam but it was many years ago.

There was one for sale in germany
(ebay http://tinyurl.com/2q8vnr)

I sent the seller a question if he would ship to Norway when there was 0 bids, and one day to go. No answer.

The acution ended with no bids.

It breaks my heart...

There is no FPGA in that minimig, so thats why nobody is interested in it..

I see, makes sense. I don't understand any german

Only before I bid I'll make use of google translate to see if there are any snags...

Herewith, I offer an almost complete MiniMig as drawn up by Dennis van Weeren designed. Almost completely because of the Spartan 3 because availability is not yet on the board soldered. It's still missing a ELKO, but what will be included because he previously at the Spartan 3 soldering would disturb. And it might not be the 3.5 mm audio jack, which I still could not make out. I have reviewed all the solder joints and there were höherwertigere components used as Dennis van Weeren recommended. For example, as one of transceiver Linear Technologies instead of a budget version. I had the part but has not yet closed to the network, but carried out several tests, which ensure operational readiness. Even the PIC controller is programmed so that only the missing components to be soldered and the fun can begin. Since the last sold on eBay complete Minimigs for approximately 300 EUR weggingen I offer my due to the absence of Spartan 3 (price approximately 30 EUR) for a relatively low price. Have fun.



UPDATE: Today (19.11.07), I get the call that I am the Spartan 3 in 4-5 weeks delivery. Upon request, and against 30 EUR fee, I will deliver it. With Instant-purchase account for the surcharge.

UPDATE (23.11.07): Because some inquiries I say again that the PIC is already programmed. Esfehlt really only the Spartan 3, a ELKO (is), and the audio connection. Otherwise, the device is running.

Pyromania, I wanted to reply to this because I've seen you ask this question a couple of times without much of a response.

I guess as one of the early owners of a Minimig, the responsibility for finding the best supplier of MMCs might be down to you (trial and error and all that). However, that isn't being helpful. Take a look at this picture:
http://www.amiga.org/gallery/index.php?n=1211
Looks like Dennis used an Apacer MMC.
Google US product search:
http://www.google.com/products?hl=en&q=Apacer+MMC&um=1&ie=UTF-8
So prices are around $17.98 USD for a 1GB card.

Hope that helps.

Thanks very much for the info HenryCase, now if I can only track down that elusive power supply for the USA.

[Pyromania]

@Belial6

My mistake, I'll call it by it's proper name from now on (MiniMig). I have seen it on the internet both ways. Thanks for the free spell check.

Would any of these be suitable as a Minimig power supply?
