Re: One off source for Minimig FPGA
« on: May 29, 2008, 12:55:29 PM »
I have all the parts except the FPGA myself.  It's about 80% done, laying in the drawer at work.

The SD card socket was indeed tricky to obtain.  I finally got one from another DIY electronics kit (ebay link).  This kit also contains a couple of other parts (pushbuttons, serial port, etc) which come in handy.

I'm interested in building more than just one Minimig, so if you come across any good offers, let me know.
Code 6502 asm or... DIE!!

Why build a minimig when you can buy one from AmigaKit & other places?

Is it cheaper, or is it just for fun?  :-?


It's definitely not cheaper, but it's very educational.  I wish every hardware component was available as a DIY package.

I looked closely at the SD card socket supplied with the kit, but in the photo is looks different from what Dennis used for Minimig.  The original part for the Minimig has the solder connections hidden somewhere in the middle of the socket, whereas the one from your link has the connections at the back.  Did it fit OK for you?


Actually - I haven't soldered it yet.  The connectors are at home, and the Minimig's at work.  Since I'm lacking the FPGA, it's all been "on hold" lately... so I haven't really thought much about it.

I'll take a look at it this weekend and double-check.

The last time I enquired about Xilinx XC3S400-4PQG208C FPGAs I was asking for the bulk price, which for 20-100 chips was £13.40 GBP each. I didn't ask for the price for single chips.


That's a really great price.  Maybe someone in the UK are willing to stock up?  I'd love to, but I'm in Norway and we have a +25% tax on imports worth more than £20.

If someone in the UK did, they could send the FPGA's abroad as "gifts" :)

Hey, I'll have two.  Maybe three.

..and, as it turns out, it didn't fit.  But it did provide me with the pushbuttons, power connector and joystick port.  And a helluva experimenter board to play with later.
