Author Topic: Who will be first??? Working MiniMIG v1.1 (Read 4731 times)

PCBs are completed, I am sure components are arriving and soldering irons and/or ovens are heating up. Who will be the first to complete their very own MiniMIG. Unless I am mistaken, Dennis produced 4 MiniMIGs, kept one and gave the other three to friends of his. Who will own working MiniMIG number 5?

Hopefully my bare PCB of the v1.1 MiniMIG will be arriving soon, but I doubt I will be first to complete the project.

So speak up and let us know when yours is working and of any changes, or problems you come across in the process.

P.S. I am looking for someone that has SMT tools and expertise to install the SMT parts on my board so I can finish the rest of the project myself. If you have these skills, or know of anyone else that can help me, send me a PMail, or post the answer here for others that may also need the help.

I wonder if some people is working on improving it with:

-hardfile support
-more ram
-HD controller
-Real floppy controller
-using a 060EC. These cpus are cheap, work with 3.3v and since you can change the FPGA to work with it, you wouldn't need to convert the 060 bus into a 030 bus so it would be very fast
-AGA support?
-some chips to handle 5v signals so you can fit an A2000 cpu accelerator?

Egads guy, walk before you can run!

My own PCB (still only halfway etching it, damn this 24-hour day) has an A500-style slot on it, but it's 3.3v rather than 5v.

I have SMT rework tools here, dunno if I'd be of any help though heh, I'm in Sydney, Australia... Shipping your board here would cost an arm, a leg and a testicle

I am building one using a V1.1 pcb from Nusim.

I have 95% of the components but there are still a few that I am having trouble with.

I am using a cheap temp controlled iron with a .4mm bit and .3mm solder and a bloody big magnifying glass!

As soon as I finish I will post my component list with RS and Digikey part numbers that I can verify are good (In both the mechanical and electrical senses). :-)

How is your project going? did you get all components from digikey?

Colin_Camper · « **Reply #8 on:** September 26, 2007, 10:02:24 AM »

95% from Digikey
I think I got the wrong SD card.
The memory, FPGA and 68k are all slightly different.
I guess I'll have to suck it and see!

Nearly everything I got from RS was not really right. E.g. the VGA connector was just the shell, etc etc.

I have my components on a spreadsheet - when I check the components I put a P for physical fit and an E for electrical compatibility. Obviously no components will have an 'E' until I build the board up and test it.

Im about to order the memory, FPGA, PIC and the 68K from digikey tonight, rest of the components ill try to find here in Finland.
Good luck, and let me know when you have a working minimig :-D
Do you have a list of all components in the minimig and their values? did not find that on minimigs homepage?

countzero · « **Reply #10 on:** September 26, 2007, 12:55:24 PM »

is it possible to put the FPGA into something like a PLLC socket ? I'm not even sure such a formfactor exists, but it would make the minimig production 100 times easier.

Would be the same amount of work really. You'd have to build a board for the FPGA to sit on first, as they don't come that way normally.

where can i find a list of all needed components
maybe i can find 80% of the stuff local
how about the spartan how to put the info in it?

AJCopland · « **Reply #13 on:** September 26, 2007, 02:24:58 PM »

You don't need to "put the info" into the the FPGA, it gets setup from the SD/MMC card. The only part that I "think" needs programming is the PIC as this is what loads the data from the SD/MMC card.

Can anyone confirm that, I'm still waiting on the boards to arrive and to get paid this month... oh and Halo3 which might hold me up just a wee 'lil bit :-D

i ordered 1 board too...for 14,99 i can mess up a bit
