Minimig PCB run - interest thread

[McVenco]

I'll buy a completely fabricated one, no matter the form factor...

[TheMagicM]

so whats the status?   did we ever get a price each and a delivery date?

Little update here, Dennis is updating the PCB afterall to V1.1, we decided it was best if he did it since it'd take too long for me to recreate it in Eagle and don't have a gerber capable editor.

Patience is key here as he is very busy with real world commitments. Once I have the new PCB though, I'll send it to my guy in China and from that point it will be two weeks before the boards arrive with me to test.

I'll keep you guys posted.

Id be very interested in 1 assembled board, depending on final pricing, please.

[Vlabguy1]

I'll buy a few...assembled and in kit form.. :-)...
Im pretty handy @ soldering chips on boards..

Firewire ports??  hehe

I used Eagle at one time, very cool and easy to use program.

Please, can you put all the ports on one side of the board?
It would make it easier to stick in some ready made computer case.

Great news Joel,  I don't know how I missed your last message earlier.  

Can you reply with a brief summary of what changes are being made for the v1.1 Minimig PCB?  Also, can you answer the question which form factor is Dennis using for v1.1, is it still 12cm by 12cm?  Will your assembled boards have the ports Dennis used, or pin headers, or will we have a choice of either?  Do you have a price for the following:

1)  Bare PCBs
2)  Bare PCB w/kit of all parts needed to complete a Minimig
3)  Assembled Minimig boards with all parts installed

Thanks for taking this on and getting these boards manufactured.

I have summarised issues that may need attention:

i am very interested in an assembled board.
and i am sure some of my friends are too.

[CD32Freak]

I'm only interested in a bare PCB, so I can put it in a frame :-D

[yssing]

Now that is a cool idea

[hifibonsai]

I'd like one as well, fully populated.

I would like to have the cpu and other chips in sockets, so that they can be switched if they fail for some reason.

Is it possible to run kickstart 3.1 rom and OS3.9 on the minimig? Is it possible to change the CPU to a 030 or 040?

A quick count gives 43 ctrl + 32 adr + 32 data = 107 i/o pins.
So there's at least 27 new pins to connect. And the current setup only have 4 free. Thus a serious reorganisation with a southbridge solution or a enterpoint/uk PGA socketed solution would be needed.

So it proberbly can be done. But not as a plugin solution to the current setup.

As for kickstart/WB I think dennis have to tell

Btw, found another assembly house: http://www.creationtech.com/printed_board_assembly.shtml

I would imagine that Kickstart 3.1 would work, as long as you had the kickstart image. I doubt OS3.9 would work though, doesn't it need at least an 020? Plus AFAIK there's no hard drive support on Minimig yet.

Anyone know if there are plans to add hard disk support? I know there might not be enough pins for an IDE interface (my preferred option, with the low price of Compact Flash cards and adapters) but UAE hardfile support would be much appreciated  :-)

Another thought - if hard disk support was added, could the 68000 be replaced by a 68010? I understand that WHDLoad works better with 68010+.

UAE hardfile support is plain verilog hacking :-)
Though the MCU would need some additional code to support write operations.
As for replacing the cpu, it's mainly a question about weather the number available fpga i/o's are enough.
