Minimig PCB run - interest thread

[AJCopland]

I'd be perfectly happy with the released board design, one unpopulated and one populated, no alterations required.

If you do go making alteration then I guess I'll have to see but I wouldn't object to IDE, a faster 68k or more ram :-D

Hi Xenepp,

I'd like one bare board and one assembled please.

Why dont they sell the PCB *WITH* components?

Because there is no "they"? The "they" you refer too is called Xenepp who will be buying and building them by hand :-D without charging for his time or skill judging by the prices he's asking.

I've PM'd him asking for one bare board and one assembled when he does another run of them. The bare board is so that with a friends help and the smt tutorials on sites like Make (etc) I can attempt building one myself.

Thats really cool that you've got some of the boards and I would still be interested in a blank board from you either in this or another batch should you do one Well done getting them done this far!

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

Actually one possible reason for real IDE would be to have CDTV emulation once ECS is working.

It'd also be good for later v2.x MiniMigs with a 32bit bus and AGA so that the CD32 can be properly emulated.

If it's as easy to do IDE as people have been saying then it makes sense to try it now as one of the low-hanging-fruit kind of tasks.

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? :-)

CDTV is OCS ;-) (Well half OCS, it has a FATTER Agnus)

The CDTV doesnt use IDE :-(

1) Put ISO images on SD card?
2) Solve other v2.x problems (RAM, CPU, FPGA) first?

I'd like to help out with some of those other problems, the SD-RAM one seemed like the biggest immediate win actually. I have no idea how to do the layout for it though.

My initial plan was to figure out what SD-RAM chip to use, someone linked to a 32Mbit (4MByte) 100/133Mhz. Then to figure out how to interface it to the FPGA, so theres some board layout to be done.

I figured that the SD-RAM would need another clock source since there are only 20MHz and 4Mhz clocks currently on the MiniMig. The example of interfacing to SD-RAM required at least 25Mhz as an input but I hadn't looked into it any further than that.

I was also hoping that Dennis or someone else would respond as to why the MiniMig would have trouble actually using SD-RAM as opposed to SRAM so there'd be a bit more information about what problems are going to be encountered.
