Feature? Surely that must read 'future'? 213.10.120.175 08:54, 2 August 2007 (UTC)[reply]

Edits

Amiga is re-implemented using an FPGA, not as a FPGA.
The linked Amiga Custom Chipset article nonexistant.
Source code were relased not specifications. But schematics,gerber etc.. were included.
PIC is a specific microcontroller, and a link to the generic term 'microcontroller' is good to hint on AVR. Not imply PIC is the only microcontroller available.
The hidden comment "This is NOT the TNT23 project" is only for those more deeply involved. Just confuses other persons. —Preceding unsigned comment added by Electron9 (talk • contribs) 13:51, August 28, 2007 (UTC)

Various claims..

The clock_dcm.v takes 4.433619 MHz from the PAL colour crystal and outputs 4.433619*(32/5) = 28.3751616 MHz to feed Agnus etc.. Any other frequences is an even division from there. Because only DCMs in the Xilinx FPGA may create fractional parts of another frequency.

The Freescale M68000 CPU most certainly don't run at 16 MHz. Because it get it's clock from the fpga (Pin101 CPU_CLK). Which produce this frequency with the clock_dcm() function. Thus 4.433619*(32/5)/4 = 7.0937904 MHz. Which is the standard frequency for an OCS A500 Amiga.

The synchronous bus may run at 4.433619*(32/5)/2 = 14.1875808 MHz, but I'm not sure. However there's not reason for it to run at anything but a even multiple below or equal to 28.3751616 MHz or thereof.

The MCU (PIC18) 20.000 MHz clock crystall is not involved with the FPGA or m68k-cpu, see connection diagram.

Minimig specification improvements might be better written as deltas. Ie what changed from version X to Y.

Please do check electrical diagrams and verilog sources before modifying anything related to this again.

Power intake is +5V DC, and current usage is approximately ~100 mA according to Dennis. (with basic setup)

External links modified (February 2018)

Hello fellow Wikipedians,

I have just modified one external link on Minimig. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Needs revision

Ooh boy, does this article need revision... It reads like a time capsule. Unfortunately I do mot have the time atm. Jalwikip (talk) 21:11, 17 April 2024 (UTC)[reply]

Lead Section

Has anyone else noticed that the website minimig.ca has an about section that is word for word the lead & original prototype section? I will put it as a reference through archive.org, but I think it may need further editing. (https://www.minimig.ca/index.php/about/) Thebest8382 (talk) 17:24, 22 June 2024 (UTC)[reply]

And nevermind, I have no clue how to add a reference without messing it up. I'll post the archived link here for any kind souls to paste in: https://web.archive.org/web/20240404230410/https://www.minimig.ca/index.php/about/ — Preceding unsigned comment added by Thebest8382 (talk • contribs) 17:46, 22 June 2024 (UTC)[reply]
