MiniMig with AGA

[freqmax]

I assume the softcore 68000 is using 32-bit adress bus?

Microcontroller with ~30 GPIO pins that interface to the A1200 keyboard matrix and PS/2-Minimig/FPGAarcade in the other. Done!

Btw, anyone seen a non-BGA S-ATA to LVTTL/LVDS bridgechip or similar that can interface to an Xilinx Spartan FPGA ..?
S-ATA = 1500 Mbit/s ; USB2 = 480 Mbit/s

@alexh, What is the chip code for those?

(like XC3S400S for a certain other chip )

I know about RocketIO, I think one of the Xilinx FPGA even has 12 of them. For that super-raid , But the catch is BGA..

I suggest the discussion regarding A1200 keyboard, PS/2 etc.. continue here: "A1200 Keyboard to PS/2 or other interface..".

[freqmax]

spans, Your physical location "may" be useful ..

BGA connectivity can't be verified easily without X-ray machines. Pro-production involves setup-fees, transportation delays, risk of misscommunication etc..
Even if you can outsource the job, doesn't mean it's particular convenient.

Guess TG68 ain't cycle compatible then? might be something that has to be fixed.

[freqmax]

trip6, Speed is not the problem. Phase alignment and in particular syncing with other signals is.

I think Bill McEven has some production plans.. ;-))

[freqmax]

How much work/time is remaining on the softcore 68020 before it's workable?

Maybe 020 software doesn't really use that many 020 specific instructions?

Hope MMU / FPU softcores follows

[freqmax]

Maybe 1-2 boards could be made locally at higher cost to iron out any layout bugs ?

[freqmax]

@mikej, In what country?

[freqmax]

Prototypes Qty < 5
54 sounds like production..

[freqmax]

Think BIG, live LARGE!  

With Xmas coming up, a large batch produced at "bulk quantity" prices could be an attractive stocking stuffer if they could find a way around the Kickstart ROM issue and bundled it with a bunch of the "free" games (Cinemaware's stuff, etc).

My consideration is mainly that any PCB layout bugs, presuming components are OK. If there is any layout mismatch even simple things like footprints. Then correcting 54 boards by hand is no easy task....
Thats why I think no more than 5 should be produced initially to make sure gerbers, pcb manufacture process and components are up to the job. Also things like heat issues, interference, stability etc.. may also screw up things.

Real production starts in the quantity of 1000s of boards. That's the usual minimum quantity to buy directly from manufacturers.

The kickstart-ROM I guess will have to be "found" by users , the alternative is to make a clone that present the same API, fits the ROM size, is bit-bang compatible at certain addresses, and runs on 68000/68020.

[freqmax]

Actually a BSD licensed AmigaOS clone that can run natively on 68000 would be really useful for a project like this.

It should have the same binary API, fit the same ROM area as the original, and implement certain sections such that some bitbang tricks will still work.

There really is a need for both v1.3 compatible w 68000, and v3.x compatible w 68020.

At least Jens has his own A-Clone in, so his interest may be affected

The FpgaArcade board is not ready yet anyway. Like Minimig were at its release.
