Minimig PCB run - interest thread

[BooBoo1200]

Very Cool :-)

@Xenepp

I'm still happy to be on the list for a bare board. Even if things don't always turn out as expected, thanks for all the work you've done so far.

@Xenepp,

The bad news, it looks like I'll not have the time to do a run of complete PCBs.

Sorry to hear that, I wanted to acquire a ready-made PCB for 'tinkering'.

Guess I will be having another look at building my own minimig board...

I'm not sure about how many will be made yet, I guess if you post here that your interested it'll give me an idea.

A little late to the party here, but sign me up for a rev1.1

Preferably with at least SMD done, even better with all soldering done .. but I'll take a bare board if that's what's going.

(form-factor not fussy, plugs vs headers not fussy, real life vs usb/firewire/ide/pci/blah/blah not fussy :crazy: .. )

I'm also interested in a Minimig but only in one with SMD parts allready soldered.

My personal wish list for a Minimig V2 would be:

- 68EC020 instead the 68SEC000 for better compatibility with the Amiga 1200 if AGA is implemented. ;-)
- IDE Port
- And a 65816 CPU. The CPU which should be used is selected with the FPGA core. Why an 65816? Because it would be a good CPU for a C64 FPGA core. This way the minimig would be a great device for C64 Fans too. And often Amiga Fans are C64 Fans too. ;-) Yes I know, the 6502 for the C64 coold be implemented in the FPGA too, but I think a CPU like the 65816 would even be better.

Why would you want an IDE port? I am almost certain we'll be able to emulate hard disk using the MMC card using existing MiniMig

Yes you are right, this would be enough, because the size of MMC is big enoug for needed hard disk size for Amiga. Couldn't this be done on Minimig V1 with an other PIC program?

But a 68EC020 switchable with 65816 for C64 Emulation would be very nice on Minimig V2.

I have read the MCU firmware. And I don't see any reason as to why not it should be possible to do adf-write and harddisc-read/write operations. Only program memory could hinder it as I see it.
I don't see any reason to have a 65816. Both that and 6502 can likely be done in HDL.
Also there simple is NO free i/o for another CPU with XC3S400 and not likely XC3S500E either.

Do you know if for the 65816 a free FPGA implementation is available which is fully compatible with it and reaches the same speed? For 6502, I know, there are som good free FPGA implementations available.

If a good 65816 FPGA implementation is available, than a real 65816 on Minimig might not necessary. So my whish list for Minimig V2 would be shrinked to 68EC020. ;-)

But I see an other problem, the program memory of the PIC. Because the PIC should than handle Amiga hard disk and disk image files read and write and also C64 disk image read and write the memory is likely be to small.

If the FPGA is upgraded from 400k to 500k gates there should be enough room for a 65816 or a 68ec020 core inside it. At the present time I do not think somebody has written any of those cores, but when it is mass produced I think somebody will write them since the source of software emulators for those (and many other) CPUs has already been made public.

@alexh

maybe you want to plug in a real hard disk from your old miggy, CDROM, DVD...

[alexh]

@crumb
Plug it into your PC, copy the files to the SD card (or the HDF on the SD card). Just like you would for WinUAE etc.

I wonder what's next to be suggested?

Bluetooth I/O and sensor bar input for a Wiimote to allow "lightgun emulation" on LCD panels? :-)

[AJCopland]

Nah you don't need sensor bar input... its just a couple of IR LEDs :-D

[freqmax]

How much ROM does CDTV / CD32 use ..?

Absolutely, Why use one computer when you can use two. Maybe you could work a Mac into the process too.

I know, what is it with these people who want to make a new Amiga that supports modern hardware standards?
